AMD’s FSR 3 know-how made a shock debut earlier this month in two video games: Forspoken and Immortals of Aveum, and we’re prepared to provide you an early look of the know-how. There’s so much to cowl on this article together with a dialogue about body pacing, picture high quality and latency.
FidelityFX Tremendous Decision 3 (FSR 3, for brief) is AMD’s reply to Nvidia’s DLSS 3, which launched body era help for RTX 40 collection graphics playing cards a couple of yr in the past. The overarching idea is that between every usually rendered body, body era can create an interpolated body to enhance the smoothness of the sport’s presentation.
FSR 3 introduces body era that is much like DLSS 3 in its performance and objectives, with AMD beginning to roll out their tackle the know-how now after saying it on November 2022.
The primary distinction between FSR 3 body era and DLSS 3 body era at a floor stage is compatibility. DLSS 3 is unique to Nvidia’s RTX 40 graphics playing cards, with Nvidia claiming that solely their Ada Lovelace structure has the optical circulate accelerator efficiency essential to drive body era.
FSR 3, then again, is offered for all graphics playing cards, with official help for AMD’s Radeon 5000 collection and Nvidia’s RTX 20 collection and above. AMD is successfully claiming that they’ve an optical circulate body interpolation system that’s performant sufficient to not require particular {hardware} accelerators, which actually disrupts the GPU options race – offered it really works properly.

With a couple of yr hole between the launch of the 2 applied sciences, at present there’s solely two video games with FSR 3 body era help, Forspoken and Immortals of Aveum. Enabling the characteristic is so simple as turning on FSR 3 upscaling after which toggling body era within the recreation’s settings.
A slide from AMD’s presentation on FSR 3 and Temporal Upscaling
In contrast to with DLSS, FSR 3 body era requires using FSR 3 upscaling, so you’re tied to FSR if you wish to entry AMD’s body gen tech and it can’t be enabled with native rendering or DLSS upscaling.
FSR 3 additionally introduces a brand new native AA mode that applies the temporal anti-aliasing and sharpening element of FSR with out upscaling for these on the lookout for higher picture high quality than what FSR often presents.
Whereas FSR 3’s recreation integration is so simple as a toggle, sadly it isn’t a know-how that “simply works.” And that is the place we have to begin speaking about FSR 3’s body pacing and configuration.
FSR 3 Body Pacing Points
FSR 3 works in another way relying on whether or not you’re utilizing variable refresh charge (VRR) know-how or not. It additionally works in another way relying on whether or not you’re gaming with VSync on or off. The precise configuration you’re utilizing drastically alters the ultimate FSR 3 output high quality and the best way it paces frames to your show. Let’s break all of it down.
Proper now, all VSync off configurations in Forspoken and Immortals of Aveum are essentially damaged with FSR 3. Frames aren’t being paced appropriately with VSync disabled, resulting in both a blurry or juddery presentation (or some mixture of each points).
Because of this in a VSync off state, FSR 3 gives zero profit. Whereas it does enhance the body charge quantity you may see in an FPS counter, the precise visible presentation is not any totally different from utilizing FSR 3 off, and in some instances may be worse.
For a greater illustration of picture high quality comparisons, try the HUB video under:
Within the video above is an instance of how VSync off with FSR 3 body era is pacing frames to the show. You may need to excuse the low high quality sluggish movement footage right here, we do not have a very nice 1000 FPS digital camera.
Each configurations are working at roughly 100 FPS with VSync off on a variable refresh charge show. Nevertheless we aren’t getting a real 100 FPS output with body era enabled; as a substitute, relative to natively rendered 100 FPS, body era seems to be outputting frames at a a lot decrease charge. We imagine with VSync off that FSR 3 will not be correctly pacing or displaying half of the frames to the purpose the place it makes little to no distinction in comparison with not utilizing body era and easily enjoying at a decrease body charge.
AMD tells us that VSync off in each launch titles is utilizing an older methodology for dealing with body era, older than the model described on their GPUOpen web site. We don’t know why an previous model of FSR 3 could be used to launch the know-how if a repair for VSync off is understood and carried out in newer code, however right here we’re.
FSR 3 body era additionally does not work correctly with any variable refresh charge configuration when gaming inside your monitor’s refresh charge vary. Usually when gaming with VRR enabled, your body charge and monitor’s refresh charge are synced to cut back judder and display screen tearing from any mismatch. FSR 3 breaks this performance.
Once we view sluggish movement footage we are able to affirm that is the case. With out body era, a 100 FPS output is constantly paced to the show. With body era enabled, the monitor’s refresh charge counter stays largely at its most (on this case 160Hz) with the occasional dip to a decrease refresh charge, so the 100 FPS output will not be synchronized with the refresh charge. This causes body pacing judder, and as some frames are being proven on display screen for longer than in a VRR state, it will possibly additionally result in elevated blur in some conditions.
Nevertheless, after we examine this to DLSS 3, we are able to see that Nvidia’s body era know-how is appropriately and precisely pacing frames and dealing simply tremendous with variable refresh charges, as you’d anticipate for a 100 FPS output on a 160Hz monitor. That is true for FSR 3 whether or not you might have an Nvidia or AMD GPU.
That is additionally true if you happen to use a body cap inside your monitor’s most refresh charge. Native rendering with a 120 FPS cap will change your VRR succesful monitor to run at 120Hz. With FSR 3 body era, capping to 120 FPS will nonetheless make your monitor run on the most refresh charge, on this case 160Hz, which is a mismatch that causes judder – regardless that the body time output graph seems smoother. The one time we noticed appropriate body pacing was when body era was in a position to max out the monitor’s refresh charge.
In follow this limits the good thing about FSR 3. The bigger the hole in output body charge and monitor refresh charge, the extra juddery and unsightly the FSR 3 expertise is. Whereas this does work higher than VSync off and the precise variety of delivered frames is larger than not utilizing body era, relying on how low the body charge is, FSR 3 can really really feel much less clean, which defeats the entire objective of the know-how.
These points are minimized at larger body charges and a better hole to your monitor’s max refresh charge. In our configuration, for instance, something above 130 FPS on my 160 Hz monitor felt fairly good and seemed clearer than not utilizing body era and subsequently enjoying at a decrease body charge. The best expertise happens when working on the max refresh charge, however just a bit below that also labored properly.
We discovered a small enchancment when disabling variable refresh charges and working at a set refresh with VSync on. My monitor’s refresh charge grew to become much less erratic, which helped tempo frames somewhat higher, however finally in case you are working FSR 3 under your monitor’s max refresh charge on this state, there may be nonetheless an opportunity of judder as we all know is the case for fastened refresh gaming. The identical applies as described earlier than, the place something above 130 FPS on my 160Hz monitor felt fairly good, however under that and particularly under 100 FPS the judder was very noticeable and never best.
With such a robust concentrate on VSync on gaming and maxing out your refresh charge, we imagine AMD hasn’t examined variable refresh charge configurations adequately sufficient, and hasn’t optimized the expertise for what we would say is the commonest and fascinating configuration that embody variable refresh charge.
In response, AMD tells us that FSR 3 was designed to be used with VSync on with the objective of maxing out your monitor’s refresh charge. Additionally they instructed us that they had body pacing working appropriately with variable refresh charges of their labs, one thing we have been unable to duplicate on both Nvidia or AMD GPUs. My expertise appears to align with different individuals testing FSR 3 body era.
With such a robust concentrate on VSync on gaming and maxing out your refresh charge, we imagine AMD hasn’t examined variable refresh charge configurations adequately sufficient, and hasn’t optimized the expertise for what we would say is the commonest and fascinating configuration that features variable refresh charge.
Just about each gaming monitor offered within the final 5-7 years helps it, so having to disable VRR or tune settings to max out your monitor’s refresh charge looks like an old style method in a world with widespread variable refresh, generally with very excessive max refreshes like 240Hz and even 540 Hz today.
FSR 3 Picture High quality vs DLSS 3
At this level it turns into apparent that FSR 3 does not run in addition to DLSS 3 in its present state because the latter does help variable refresh charges, VSync on, and VSync off. With DLSS 3 body era, you should utilize any configuration you want, activate the body era toggle and expertise correctly paced interpolated frames.
For a greater illustration of picture high quality comparisons, try the HUB video under:
With FSR 3 body era you need to guarantee your output body charge is excessive sufficient, most likely disable variable refresh charges, and ensure VSync is on. That is an excessive amount of fiddling round when the direct different and competitor know-how successfully “simply works.”
Now let’s discuss in regards to the precise high quality of FSR 3 body era when utilized in an excellent configuration: maxing out your monitor’s refresh charge. The standard of interpolated / generated frames might be the largest power of FSR 3 proper now and one side that AMD have largely gotten proper.
The most important win for FSR 3 body era is how FSR handles UI parts. DLSS 3 struggles with this, and whereas it has improved since launch, there are nonetheless titles that do not have excellent dealing with of UI parts, typically that includes garbled, distracting, terrible UI in movement. This was by far essentially the most noticeable concern from Nvidia’s body era. With FSR 3, we did not spot any UI points testing Forspoken or Immortals of Aveum. Each video games with FSR 3 body era deal with the UI flawlessly, no garbling, no distracting points, which eliminates the largest artifact seen from this know-how.
For a greater illustration of picture high quality comparisons, try the HUB video under:
Even in a title like Immortals of Aveum which typically has good UI rendering from each FSR 3 and DLSS 3, FSR 3 has the sting. Once we have a look at semi-transparent UI parts, for instance, FSR 3 higher handles interpolation behind the transparency in movement in comparison with DLSS 3. It’s because FSR 3 has a mode for recreation builders that absolutely decouples the UI loop from the body era loop. We suspect that is how most video games will deal with the UI with FSR 3, though AMD did point out there may be an possibility recreation builders can use to place the UI by means of the interpolation cross, one thing I hope will not be used if it creates important artifacting.
Like with DLSS 3, it is exhausting to identify any artifacts from the FSR 3 generated frames themselves when the ultimate output body charge is within the 100 to 120 FPS vary or larger – which generally corresponds to a local 60 FPS render charge or larger. Whereas the problems are evident when slowing down the footage and inspecting body by body, having these decrease high quality frames interspersed with larger high quality frames considerably reduces their visibility and the way noticeable these artifacts are. The upper the body charge, the shorter every of those frames is being proven.
And just about identically to DLSS 3, FSR 3 body era falls aside when used at a low native render charge, particularly when taking 30-40 FPS and turning it into 60-70 FPS. This isn’t a really helpful use case for body era, it simply does not work properly, artifacts in movement are fairly noticeable and this considerably reduces visible high quality. Having a comparatively excessive output body charge is essential to making sure all body era tech works properly.
Having a comparatively excessive output body charge is essential to making sure all body era tech works properly.
When extra carefully assessing the standard of FSR 3 generated frames, we might say their high quality will not be fairly pretty much as good as DLSS 3 generated frames, though in follow at a excessive sufficient body charge it is troublesome to inform the distinction.
For a greater illustration of picture high quality comparisons, try the HUB video under:
Typical ache factors for body era are any tremendous particulars, like wires or chains. When slowed down (as proven within the video) you may see that each second body has garbled chain element for each DLSS and FSR body era, though DLSS finally ends up much less garbled. Transparency results journey up body era, with FSR 3 once more wanting a bit blurrier in its generated frames for this magical white impact.
Quick advanced movement may cause interpolation points as properly. When altering your weapon in Aveum, each DLSS 3 and FSR 3 produce a whole lot of garbling as every body struggles to cope with the speedy modifications in movement. Nevertheless on shut inspection the extent of garbling is bigger on the FSR 3 aspect, although neither tech may very well be described as producing prime quality frames on this scenario.
In lots of different conditions you may see comparable output from DLSS 3 and FSR 3 body era, a minimum of based mostly on the present pattern of 1 that we’ve. For instance, easy movement like digital camera pans or translation typically works properly, with each applied sciences counting on movement vectors to ship the identical stage of element as in ‘actual’ frames. Extra advanced textures and parts like foliage can have points throughout easy movement, however we did not see a transparent winner for this between DLSS and FSR. We suspect like a whole lot of different implementations of DLSS and FSR, that these high quality battles will range from recreation to recreation.
Whereas artifacts may be exhausting to identify with a excessive sufficient body charge, it is fairly clear throughout each FSR 3 video games that generated frames aren’t equal to usually rendered frames in high quality. Utilizing both DLSS or FSR with out body era ensures the least quantity of artifacting, however with body era on, it is uncommon to get the “excellent” generated body. When enabling FSR 3 you may have to just accept that the ensuing picture high quality from every body is decreased to enhance the smoothness of the presentation, with a decrease high quality output in comparison with rendering the sport natively on the identical body charge.
However the largest concern with FSR 3 picture high quality will not be the generated frames themselves, it is the standard of FSR upscaling, which AMD tells us has solely obtained minor enhancements (if any) relative to FSR 2.2.
Because of this in a battle between FSR 3 and DLSS 3 body era, DLSS usually has noticeably superior picture high quality – and that is right down to DLSS having higher upscaled picture high quality, which is able to dictate the standard of the “actual” frames which can be proven and enter into the interpolation algorithm. So whereas the distinction in generated body high quality is not all that noticeable at a excessive body charge, the general distinction in picture high quality from upscaling actually is.
For a greater illustration of picture high quality comparisons, try the HUB video under:
Even at a 4K decision, which we used for all picture high quality comparisons within the movies, in each Forspoken and Immortals of Aveum, DLSS upscaling is superior to FSR upscaling and that impacts the visible presentation for body era. Specifically, DLSS has higher picture stability and fewer shimmering, in addition to often higher tremendous element reconstruction in movement.
Even when pitting DLSS High quality mode up in opposition to FSR Native AA upscaling, DLSS High quality was higher in each titles evaluated, it merely has higher picture stability in movement which is noticeable as each video games are heavy on foliage and particle results. Whereas we did not extensively take a look at this, we anticipate the hole to widen because it usually does when testing decrease render resolutions or decrease output resolutions.
This finally ends up because the defining distinction in picture high quality between the 2 strategies. As FSR 3 body era requires using FSR upscaling, you’re locked into utilizing that upscaling even when a better high quality know-how is offered. In a face to face battle with DLSS 3 body era utilizing DLSS upscaling, FSR 3 has decrease total picture high quality due to this regardless that we have been okay with the standard of FSR 3 generated frames. Till AMD can enhance the standard of their upscaling element, this hole between AMD and Nvidia tech will stay.
For a greater illustration of picture high quality comparisons, try the HUB video under:
The compelled use of FSR upscaling with FSR 3 body era additionally locks out probably superior combos. For instance, Nvidia RTX 30 collection homeowners would have a greater expertise utilizing DLSS upscaling with FSR body era, as they can not entry DLSS body era however can use DLSS upscaling.
We think about AMD does not wish to give Nvidia homeowners the very best expertise with FSR body era, therefore the explanation for locking it to FSR upscaling for characteristic parity throughout Radeon and GeForce GPUs. However this does find yourself hurting Radeon homeowners, too, as a result of a recreation like Forspoken appears higher with native TAA than utilizing FSR upscaling and even the FSR Native AA mode. Getting access to native rendering + body era, or DLSS + FSR body era, and even XeSS + FSR 3, could be best.
FSR 3 Latency and Efficiency
Lastly, let’s discuss latency and FPS output efficiency. On a Radeon RX 7900 XTX, FSR 3 is sort of efficient at growing the output FPS. When utilizing the Native AA mode within the scene we examined in Immortals of Aveum, we went from 43 FPS to 79 FPS, an 83% enhance.
On the identical time, latency decreased as a result of AMD’s built-in latency lowering tech that’s utilized when body era is enabled. So with FSR 3 on, we ended up seeing a 23ms drop to latency, noting that the muzzle flash we have been testing in Aveum is not prompt on mouse click on therefore the excessive total numbers.
Utilizing High quality upscaling as a substitute, we noticed body era enhance FPS from 71 to 122, a 72 p.c enhance. Latency on this configuration dropped by 8ms. Nevertheless the bottom latency mode right here was nonetheless rendering at a better native body charge, FSR with Efficiency mode upscaling delivered 91 FPS – decrease than FSR 3 High quality with body era – but it surely had round 10ms much less latency.
One attention-grabbing discovery is that for suitable Radeon GPUs, at present Anti-Lag+ does not impression latency to any important diploma with FSR 3 enabled. Whereas Anti-Lag+ does have a big effect for non body gen configurations, slicing FSR High quality mode latency by 33ms on the identical body charge, this does not apply to border era. AMD confirmed these findings, noting that proper now Anti-Lag+ is ineffective within the two FSR 3 launch titles and the driver-side characteristic and its corresponding profiles for these video games wants extra work to correctly detect FSR 3 body era output.
On a GeForce RTX 4090, there was no latency enchancment between body era on or off. When utilizing FSR 3 High quality we noticed round 105ms of latency at 84 FPS within the scene examined, and with body era that improved to 140 FPS with 108ms of latency. The RTX 4090 did not profit fairly as a lot from FSR 3 body era because the Radeon 7900 XTX did, although the margins between them when it comes to share uplift weren’t huge.
Numerous AMD’s advertising has targeted on FSR 3 offering each a better body charge and decrease latency than native rendering, that are the identical claims that Nvidia makes for DLSS 3 body era. Nevertheless, what we have seen is that almost all of this latency profit is from additionally making use of upscaling, not from the body era element itself which does not enhance latency to the identical diploma as working at a better native render charge. We subsequently find yourself with the identical scenario as DLSS body era, the place it does enhance the smoothness of the presentation, however does not really feel as responsive as true larger body charge gaming.
The true kicker for FSR 3 latency is that Nvidia’s present DLSS 3 implementation delivers notably decrease latency as a result of its full integration with Reflex. On a GeForce RTX 4090, Reflex gives a strong latency enchancment: when utilizing DLSS High quality upscaling and no body era, Reflex itself reduces latency from 106 to 87ms. It is a comparable profit we noticed from Anti-Lag+ on the Radeon aspect, the place we went from 122 to 89ms of latency below comparable situations.
However as Reflex works and is at all times enabled with DLSS 3 body era, in our testing we noticed an output body charge of 125 FPS for 90ms of latency utilizing High quality upscaling. FSR 3, with out Reflex, delivered 140 FPS for 108ms of latency. So whereas FSR body era was in a position to enhance the body charge by 67%, versus only a 42% enhance for DLSS body era, DLSS ended up with 18ms decrease latency.
That is the place the dearth of compatibility for FSR 3 with Anti-Lag+ hurts. The RTX 4090 utilizing Nvidia body era tech and Reflex delivered 125 FPS and 90ms of latency. The RX 7900 XTX utilizing AMD body era tech and Anti-Lag+ delivered 124 FPS with 107ms of latency. In a greatest vs. greatest comparability that provides Nvidia the latency edge, till AMD can get Anti-Lag+ working successfully. And provided that you should utilize Reflex on an Nvidia GPU alongside FSR 3, at present the bottom latency experiences with FSR 3 know-how might be on an Nvidia GPU the place that tech is built-in.
It isn’t all dangerous information although. These efficiency figures do counsel that the optical circulate cross in FSR 3 has much less overhead than the optical circulate cross in DLSS 3, that means that FSR 3 delivers a better FPS enhance from the identical base body charge. However till latency is equalized this does not lead to a greater expertise from FSR – and will not till upscaling picture high quality is improved both.
Backside Line
Total, we aren’t impressed with what we have seen from AMD’s FSR 3 to date. The characteristic appears rushed, incomplete, and never absolutely prepared for prime time. There are too many incompatibilities and configuration points, which stand out badly in comparison with Nvidia’s DLSS 3, itself a characteristic with points. The ensuing FSR 3 body era expertise is troublesome to suggest outdoors just a few area of interest use instances.
The identical form of caveats that we talked about with DLSS 3 additionally apply to FSR 3: to keep away from seen artifacts in generated frames, you may want a base body charge of a minimum of 60 FPS with a closing output round 100 to 120 FPS. And provided that body era doesn’t enhance latency, for that true excessive refresh charge expertise, you may desire a base body charge of 100 to 120 FPS (with a closing output above 200 FPS) for the responsiveness we usually affiliate with the very best gaming experiences.
Because of this we refer to border era as a characteristic that enhances the sport’s smoothness, quite than one thing that improves total efficiency – the advantages are solely visible in nature.
To be solely clear:
- Should you’re a gamer that does not have the GPU efficiency to hit 60+ base body charge targets, then body era – DLSS 3 or FSR 3 – is not going to ship an excellent expertise.
- Should you’re a gamer that’s solely enjoying at 60 FPS however needs to enhance that to a real excessive refresh charge expertise, body era is not correctly able to that.
- Should you’re a multiplayer gamer that particularly needs to extend body charges to entry decrease latencies and enhance responsiveness to make you extra aggressive, body era is ineffective for that.
FSR 3 is not any higher than DLSS 3 at any of these facets that, proper now, are elementary to border era. The place AMD stumbles is that they’ve taken a characteristic that already has considerably restricted usability and restricted it additional. Not solely do you now want to fret about base body charge, however you may even have to make sure you’ve arrange VSync appropriately and are pumping out sufficient frames to keep away from judder.
Because of this we refer to border era as a characteristic that enhances the sport’s smoothness, quite than one thing that improves total efficiency – the advantages are solely visible in nature.
You may need to be happy with sacrificing correct variable refresh charge performance – a characteristic we strongly suggest each gamer makes use of – to entry body era. There are conditions the place that commerce off alone will not be price it, as FSR 3 may be much less clean than not utilizing it, defeating the entire objective of a know-how designed to enhance smoothness.
That is to not say FSR 3 by no means works properly.
If in case you have a fairly excessive output body charge, and are working at or close to your monitor’s most refresh charge with VSync on, the FSR 3 body era expertise may be smoother and higher than not utilizing body era. However when we’ve DLSS 3 body era that – to make use of an Nvidia-ism “simply works” with options like VRR – going backwards on compatibility with FSR 3 actually stands out.
AMD has clearly put a whole lot of work into guaranteeing the body era a part of the know-how works properly, with quick and efficient interpolation. It has decrease overhead than DLSS 3 body era, it has zero points rendering UI that we have seen to date, the overall high quality of interpolated frames is appropriate, and it really works throughout all graphics playing cards – no particular {hardware} required. That is a win for FSR 3, and it is essentially the most spectacular side of what AMD has produced and does present a strong basis for enchancment.
However all that nice work that is been put into producing frames is let down by AMD’s inferior upscaling know-how, which you’re locked into utilizing with FSR 3 body era. The total picture high quality – factoring in generated frames and regular frames – is just higher from DLSS 3 and that is largely right down to Nvidia’s upscaler. With out substantial enchancment to FSR upscaling, particularly at decrease resolutions, DLSS 3 will proceed to supply a greater total bundle than FSR 3.
FSR 3 can be let down on the latency entrance with its incompatibility with Anti-Lag+ for the time being, that means that DLSS 3 on an Nvidia GPU delivers decrease latency on the identical output body charge than FSR 3 on an AMD GPU. The gulf widens for Radeon RX 6000 collection which may’t even use Anti-Lag+ in any respect, and homeowners of older Nvidia GPUs might be praying for Reflex in FSR 3 titles because the built-in latency lowering tech in FSR 3 is not overly efficient.
AMD says that a few of these points might be improved. They’re engaged on Anti-Lag+ compatibility, VSync off has been fastened in a more recent model of FSR 3, they usually’re conscious of VRR compatibility points. However a few of these ought to have been resolved earlier than launch, so that everybody that turns it on is handled to a fantastic expertise. As an alternative, evidently AMD rushed this out to make a September launch deadline, assuaging stress that was placed on themselves by saying FSR 3 far too early.
We will solely consider FSR 3 on what’s in entrance of us proper now, which is integration into two video games with loads of points. If you should utilize FSR 3 to max out your monitor, we predict the expertise might be fairly good for you and we would most likely suggest giving it a attempt. If that is not attainable, it is exhausting to justify utilizing proper now.
And that is actually the current state of FSR 3. It is not overly aggressive with DLSS 3, and it does not do a lot to shut the characteristic hole between AMD and Nvidia, even when we ignore the big distinction within the variety of supported titles. If AMD can allocate assets to enhance FSR 3, it ought to be attainable to get it to that stage we wish although. Remedy the body pacing and VRR compatibility points, get it working with Anti-Lag+ and – maybe essentially the most troublesome of all – enhance the standard of FSR upscaling and FSR 3 could be the gold commonplace for body era know-how given its low overhead and broad compatibility.
