FidelityFX Super Resolution 2.0 is AMD’s second try at providing a broad recreation upscaling know-how to compete with Nvidia’s DLSS. In this text we’ll be utilizing the sport Deathloop which helps DLSS, FSR 1.0 and FSR 2.0 to benchmark and examine a number of GPUs from present and former generations, together with the GTX 1070 Ti, GTX 1650 Super, RTX 2060, RTX 3080, and on the Radeon camp, the RX 570, Vega 64, RX 5700 XT, and RX 6800 XT.
Since the discharge of DLSS 2.0 over two years in the past, it is steadily develop into a key promoting level for Nvidia’s RTX GPUs, plenty of avid gamers have been shopping for GeForce GPUs particularly for this characteristic, and AMD has been engaged on one thing to counter that for his or her Radeon clients.
AMD’s first try, now referred to as FSR 1.0 was launched a couple of 12 months in the past and whereas we discovered that FSR 1.0 was efficient in some conditions, significantly at 4K utilizing the Ultra Quality mode, it in the end wasn’t nearly as good as DLSS total. The picture high quality at 1080p was unimpressive and the Performance mode regarded worse than DLSS.
FSR 2.0 is a major improve to the upscaling know-how, transferring from a spatial method to temporal. If you need to be taught extra about how FSR 2.0 works, we coated a number of data when it was first introduced so it is price revisiting that.
The shift to temporal scaling permits FSR 2.0 to mix present body data with information from earlier frames and movement vectors to reconstruct the ultimate picture, using much more information than is feasible with spatial scaling. By getting access to all this information, it is attainable for FSR 2.0 to provide “higher than native” outcomes, like Nvidia additionally claims for DLSS.
FSR 2.0 vs DLSS 2.0: How they work
Where FSR 2.0 and DLSS differ is in how they strategy the puzzle of reconstruction and selecting which bits of knowledge to make use of. DLSS takes a closed-source AI primarily based strategy, which requires particular directions unique to Nvidia’s Tensor core {hardware}.
FSR 2.0 would not use AI in any respect, as an alternative utilizing a hand-tuned algorithm that is open-source and helps a variety of {hardware}, identical to FSR 1.0 – tensor cores or different specialised AI processing blocks are usually not required. We had been in a position to get FSR 2.0 engaged on 5-year-old {hardware} with none problem, extra on that later.
The first alternative to guage FSR 2.0 got here with Deathloop, a recreation which additionally helps FSR 1.0 and DLSS, so we might do a pleasant comparability between at present’s foremost upscaling applied sciences from the 2 GPU distributors. Check out the video under for lots of element on how visible high quality differs between FSR 2.0 and DLSS in Deathloop.
Now I would not name this an FSR 2.0 “overview” simply because we’re a pattern of 1 recreation. We’ll want greater than that to make a definitive name on FSR 2.0 vs DLSS, however on the very least it is a good preview of what FSR 2.0 can do.
Deathloop can be a very good recreation to check with as a result of DLSS could be very efficient on this title. It’s among the finest examples of DLSS producing a “higher than native” picture, whereas FSR 1.0 seems to be lower than superb.
FSR 2.0 Settings
FSR 2.0, like DLSS, has three high quality modes out there in Deathloop: Quality, Balanced and Performance, which correspond to a 1.5x, 1.7x and a couple of.0x scale issue respectively, roughly in step with what Nvidia presents. This signifies that at 4K, utilizing FSR 2.0 Quality means we’re upscaling from 1440p to 4K, whereas utilizing the Performance mode provides us a 1080p to 4K upscale.
FSR 2.0 is a extensively supported temporal upscaling resolution, that means it could possibly work throughout a variety of {hardware} and that is precisely what we’ll be doing at present. We’ve examined GPUs from 4 generations of AMD and Nvidia releases to see how properly FSR 2.0 scales on totally different architectures.
For at present’s testing, we’re utilizing a Ryzen 9 5950X check system outfitted with 16GB of low latency DDR4-3200 reminiscence, working the newest publicly out there drivers for AMD and Nvidia. We’ll be evaluating FSR 2.0 to the subsequent greatest out there upscaling resolution for the GPU at hand, so for RTX 20 collection playing cards and newer we’ll be evaluating to DLSS, and every thing else to FSR 1.0.
To stop CPU bottlenecks, we have run Deathloop at the highest quality playable settings for every GPU, which incorporates ray tracing enabled on larger finish playing cards. Deathloop is a demanding recreation on GPU reminiscence, and a few of the playing cards we have examined have solely 4 GB or 6 GB of VRAM, which causes points on the best settings and principally bottlenecks the cardboard – that means we do not see the actual advantages of FSR 2.0 or different upscaling algorithms. For these GPUs, we have decreased the settings to an applicable degree that does not trigger a bottleneck.
Benchmarks
Radeon RX 570: FSR 1 vs. FSR 2 vs. Native
We’ll begin right here with the oldest and slowest card within the line-up, AMD’s trusty Radeon RX 570 4GB, which was launched manner again in 2017. This recreation struggles to run Deathloop at 1440p utilizing even Medium settings, however with upscaling we will get a efficiency uplift at a minimal price to visuals.
The RX 570 would not profit from FSR 2.0 to just about as vital of a level. We do get a efficiency uplift, however it’s only a 10 % acquire from the FSR 2.0 Quality mode, and 27 % from the Performance mode.
It’s nonetheless price utilizing, however not the moment 40%+ positive factors we noticed from the newest architectures. You may also see that FSR 1.0 is certainly sooner, which wasn’t the case with RDNA2 both. With the 6700 XT, sometimes FSR 2.0 Quality mode ran higher than FSR 1.0 Ultra Quality. But with the RX 570, it is the much less taxing FSR 1.0 that runs just a few frames higher. However, I’d nonetheless suggest utilizing FSR 2.0 right here because the visible high quality is considerably superior at 1440p.
At 1080p, FSR 2.0 was extra able to a efficiency uplift. The Quality mode was giving a 14% increase over native rendering, and the Performance mode (which we do not actually suggest at this decision) was 26 % sooner. This does assist the RX 570 obtain an much more playable body fee, however it’s clear the positive factors from this outdated, mainstream GPU are restricted.
GeForce GTX 1650 Super: FSR 1 vs. FSR 2 vs. Native
The GeForce GTX 1650 Super can be an entry-level GPU however it’s a good bit newer however would not help DLSS because it lacks tensor cores. Like the RX 570, the GTX 1650 Super would not profit massively at 1440p with both FSR 2.0 or 1.0 on this title, and evidently even Medium settings is a little bit of a stretch right here.
The FSR 2.0 Quality mode was solely 6 % sooner than native, and the Performance mode barely improved up on that. In comparability, FSR 1.0 was in a position to ship significantly better body charges, with the Quality mode there delivering larger FPS than FSR 2.0 Performance.
However the positive factors at 1080p had been extra acceptable. The FSR 2.0 Quality mode was 15 % sooner than native, much like what was seen on the RX 570, and the Performance mode elevated that determine to 29 %. Not earth shattering outcomes – and FSR 1.0 is certainly sooner on this entry-level GPU – however usable. I’ll have an interest to see how funds GPUs like this fare in different FSR 2.0 video games to see if it is extra of a recreation factor or extra of an FSR 2.0 algorithm factor, however actually it appears there simply aren’t that many GPU sources to go round to run one thing like FSR 2.0.
Radeon RX Vega 64: FSR 1 vs. FSR 2 vs. Native
Let’s return in time to take a look at FSR 2.0 working on the Radeon RX Vega 64, one other 5 12 months outdated product. Using Ultra settings at 1440p, FSR 2.0 did present a modest efficiency uplift, 25 % for the Quality mode in comparison with native rendering, which was sufficient to take the sport as much as a 60 FPS common.
Unlike with the entry-level playing cards we had been simply , we’re again right into a state of affairs the place the FSR 2.0 Quality mode performs higher than FSR 1.0 Ultra Quality, and for that purpose FSR 2.0 is certainly the popular possibility on account of its significantly better picture high quality.
At 1080p, I really noticed much less of a acquire than at 1440p for FSR 2.0 because it looks like pure shading is not essentially the primary limiting issue for efficiency on Vega 64. If shading efficiency is not the primary bottleneck, then decreasing the render decision might solely have restricted positive factors, which appears to be taking place right here. Other areas to efficiency, like reminiscence or geometry, may very well be holding us again from additional positive factors. But both manner we nonetheless do get a efficiency uplift.
GeForce GTX 1070 Ti: FSR 1 vs. FSR 2 vs. Native
On Nvidia’s Pascal structure we see an analogous state of affairs to Vega 64. Using Ultra settings at 1440p, the GTX 1070 Ti was in a position to obtain 20 % higher efficiency going from native rendering to FSR 2.0 Quality, and 41 % utilizing FSR 2.0 Performance. FSR 1.0 performs higher on this structure, particularly at decrease render resolutions, however I’d nonetheless desire to make use of FSR 2.0 on account of its larger picture high quality.
At 1080p, as soon as once more extra modest positive factors of 15 % for the Quality mode, much like Vega. It’ll be fascinating to see how this holds up in different titles, however FSR 1.0 wasn’t precisely miles higher for one thing like its Ultra Quality setting. So I’m nonetheless happy that FSR 2.0 is usable right here and a greater possibility than AMD’s older FSR model.
Radeon RX 5500 XT 8GB: FSR 1 vs. FSR 2 vs. Native
Let’s check out a first-generation RDNA product, the RX 5500 XT 8GB. At 1440p, FSR 2.0 Quality mode was in a position to ship 24 % higher efficiency than native rendering, a a lot bigger uplift than with the RX 570 regardless of each playing cards working at roughly the identical FPS natively underneath the circumstances we examined. 45% higher efficiency was additionally attainable utilizing the Performance mode, and total that is preferable to FSR 1.0.
At 1080p I additionally noticed respectable positive factors, 21 % for FSR 2.0 Quality mode and 37 % for FSR 2.0 Performance, once more delivering outcomes which are preferable to utilizing FSR 1.0. Yes the FSR 1.0 Performance setting provides you just a few additional FPS, however your eyes will not forgive you for utilizing such a low high quality setting.
Radeon RX 5700 XT: FSR 1 vs. FSR 2 vs. Native
Under the identical structure household, let’s now have a look at the a lot sooner RX 5700 XT. With the identical structure and similar reminiscence capability at hand, FSR 2.0 clearly does profit from extra GPU sources. At 1440p utilizing FSR 2.0 Quality mode, we noticed a 34 % efficiency uplift, larger than the 24% we noticed for the 5500 XT. A bigger uplift was additionally attainable for the Performance mode, 61 % right here in comparison with 45% for entry-level RDNA.
At 1080p we’re in a position to get a 27 % efficiency uplift in comparison with native rendering utilizing FSR 2.0 Quality mode, and a 44% uplift utilizing the Performance mode. With these extra mid-range merchandise it actually would not make sense to make use of FSR 1.0 because the Ultra Quality mode runs slower than FSR 2.0 for as soon as once more, worse picture high quality.
GeForce RTX 2060: FSR 2 vs. DLSS vs. Native
Now let’s check out Nvidia’s Tensor core outfitted Turing structure beginning with the RTX 2060. With this GPU, FSR 2.0 efficiency is much like what we see with the RTX 3060 Ti (under), in that DLSS is barely sooner than FSR 2.0 total, however not considerably so.
FSR 2.0 Quality mode was able to a reasonably unimpressive 18 % efficiency uplift, however DLSS Quality mode solely improved that to a 21 % acquire, so bit a lot of a muchness. The greatest outcomes for DLSS had been the Performance mode, which ended up 6% sooner than the equal FSR 2.0 setting.
Then at 1080p, related story. Only a 13 % efficiency uplift for FSR 2.0 Quality mode in comparison with native, with DLSS Quality mode delivering a 19 % uplift. At 1080p this does make DLSS the favorable possibility because it additionally tends to look higher, however neither possibility is delivering an enormous efficiency improve – although I’d actually take it if I used to be struggling to hit a playable body fee.
GeForce RTX 2080: FSR 2 vs. DLSS vs. Native
Some of essentially the most fascinating outcomes are these with the RTX 2080. At 4K, FSR 2.0 was able to a 26 % efficiency uplift utilizing the Quality mode in comparison with native, nonetheless the positive factors with DLSS had been a lot bigger at 40 % for the equal mode.
On this GPU, DLSS was 10 to 12 % sooner at 4K, which is a major margin and clearly makes DLSS the favorable possibility. Again we do not know the way FSR 2.0 works precisely, so we do not know which form of GPU sources it favors, however I believe the outcomes on the 2080 are a bit of disappointing, particularly when DLSS could be very efficient.
It’s an analogous state of affairs at 1440p. The efficiency uplift from FSR 2.0 Quality was 18 % in comparison with native rendering, however DLSS Quality was reaching a 26 % uplift. Not as giant of a distinction in favor of DLSS, however Nvidia’s method was nonetheless round 7 % sooner total, so once more for 2080 house owners it might make sense to make use of DLSS.
GeForce RTX 3060 Ti: FSR 2 vs. DLSS vs. Native
Radeon RX 6800 XT: FSR 1 vs. FSR 2 vs. Native
Let’s check out some fashionable high-end GPUs. At 4K with the RX 6800 XT, FSR 2.0 Quality mode was efficient, delivering a 28 % efficiency acquire over native rendering. Using the Performance mode elevated that to 61 % over native, and with most modes both matching or beating FSR 1.0 it is clear that on a high-end card like this taking part in a excessive decision try to be utilizing FSR 2.0.
Radeon RX 6700 XT: FSR 1 vs. FSR 2 vs. Native
GeForce RTX 3080: FSR 2 vs. DLSS vs. Native
Then for the RTX 3080 utilizing the identical settings at 4K, we see a bigger acquire of 38 % for FSR 2.0 Quality vs native, and 74 % for the Performance mode. However like with different Nvidia GPUs that we have benchmarked, DLSS is the sooner possibility, delivering 4 to six % larger body charges on the equal high quality settings to FSR 2.0. So my normal ideas on utilizing DLSS over FSR 2.0 on Nvidia’s newest GPUs holds true.
What We Learned
It’s clear that FSR 2.0 runs greatest on the newest GPU architectures like AMD’s RDNA and RDNA2 designs, in addition to Nvidia’s Ampere. These GPUs persistently delivered one of the best outcomes by way of a efficiency uplift in comparison with native rendering. We do not assume it is unreasonable to count on minimal positive factors of 30 to 40 % utilizing FSR 2.0 Quality mode on fashionable GPUs.
In all conditions it nonetheless made sense to make use of or not less than think about using FSR 2.0 as we did not see efficiency go backwards, and outcomes had been typically favorable in comparison with FSR 1.0, however there are some cases the place positive factors are smaller than anticipated.
However it is not simply the GPU structure that influences efficiency. Like we noticed a number of years in the past when testing DLSS, a key part can be the native rendering body fee: you will get larger positive factors in case your baseline FPS is decrease.
This is as a result of FSR 2.0 has a hard and fast rendering price, which takes up a bigger proportion of the entire body rendering time at larger body charges. But even when your baseline is 100 FPS or extra, FSR 2.0 can nonetheless present stable positive factors on newer architectures, offered you do not run into CPU bottlenecks.
It additionally appears to be the case that FSR 2.0 runs higher on GPUs which are merely sooner total, as we noticed when evaluating the RX 5700 XT and RX 5500 XT: similar structure, similar settings, but the positive factors from the 5700 XT had been higher regardless of the next baseline FPS. This can be what AMD recommended at launch: an extended FSR 2.0 processing time for much less highly effective GPUs.
It is smart that playing cards with extra sources might run the algorithm sooner, particularly because it would not make the most of devoted {hardware}. When the algorithm is run sooner, it makes use of up proportionally much less of the time it takes to render every body, which may give a efficiency acquire benefit.
This can be related for funds and older GPUs. Cards just like the RX 570 and GTX 1650 Super are merely taking longer to course of FSR 2.0, which ends up in extra restricted efficiency uplifts even in “excellent” circumstances for upscaling. Compounding this are the restrictions of older architectures, for instance if elements of FSR 2.0 makes use of FP16 processing like FSR 1.0, then the algorithm should fallback to FP32 processing on GPUs architectures like Polaris that do not natively help FP16, hurting efficiency. We do not but have the complete image on what architectural options are obligatory for max FSR 2.0 efficiency, however we would be stunned if FP16 wasn’t an element.
Having that stated, even 5 12 months outdated GPUs can run and profit from FSR 2.0, which you’ll be able to’t say for DLSS. We’ll actually take a ten to twenty % efficiency uplift from this temporal algorithm on these playing cards, and would use it over FSR 1.0 regardless of lesser efficiency positive factors.
Across the 4 GPUs we examined at present that additionally help DLSS, from each Turing and Ampere generations, FSR 2.0 efficiency will get near DLSS utilizing equal high quality settings. However, DLSS sometimes does run higher, as much as 12% sooner in one of the best case situation on the RTX 2080. So for Nvidia GPU house owners with Tensor outfitted playing cards, our advice can be to make use of DLSS, for the small efficiency benefit and likewise as a result of in some conditions it delivers higher picture high quality as properly.
Finally, it is price repeating that it is a pattern measurement of 1 recreation. We’ll must do extra in depth testing just a few months down the observe to see how FSR 2.0 works throughout a wider vary of titles. By then we must also have the FSR 2.0 supply code and hopefully specialists in that space can dive in and provides us a very good image of what is going on on. But for now, we will nonetheless be taught a bit concerning the optimum conditions for FSR 2.0 in Deathloop, so hopefully this testing has been useful.
