FSR 2.0 tested: AMD’s new upscaler closes the gap on DLSS
AMD’s FSR 2.0 upscaler is out now – in only one game, Deathloop, but still. This is a big moment for the heavily upgraded FSR (FidelityFX Super Resolution), as it’s basically attempting to fight Nvidia’s rival DLSS (Deep Learning Super Sampling) with some of its own tactics. There’s none of Nvidia’s machine learning enhancements, but whereas FSR 1.0 was a simple spatial upscaler – meaning data used for upscaling a frame could only come from within the frame itself – FSR 2.0 uses a temporal upscaling technique similar to that of DLSS. This allows it to draw data from previous frames as well, producing a sharper, higher-quality image.
The lack of machine learning also has the upside of keeping FSR 2.0, like FSR 1.0, compatible with any reasonably recent gaming GPU. Nvidia may make most of this generation’s best graphics cards, but you won't need something brand new and super powerful to let FSR 2.0 boost your frame rates. To find out how well it works, compared to both DLSS and FSR 1.0, I reinstalled Deathloop and gave all three upscalers a whirl.
Upscaling works by rendering games at a lower resolution than your monitor’s native res, then reconstructing each frame to make it look as close to native as possible - sometimes even better. This helps take the sting out of demanding resolutions like 4K, whereas it’s not so good for 1080p as the rendering resolution will be so low that even a good upscaler will struggle to make up the sharpness deficit.
I tested Deathloop’s upscalers on an RTX 3070 GPU, matched with an Intel Core i5-1600K and 16GB of RAM. Before we get into FPS gubbins, though, let’s take a look at how FSR 2.0 improves on 1.0’s general visual quality.
Just fyi, “Quality” is the highest possible setting for both FSR 2.0 and DLSS; with FSR 1.0, “Quality” is in fact the second-highest, with “Ultra Quality” being the best. “Balanced” is the second-highest for FSR 2.0 and DLSS, making it the equivalent of “Quality” on FSR 1.0. Not confusing at all.
That aside, FSR 2.0 is definitely an aesthetic upgrade on FSR 1.0. Fine details that would previously be blurred by the upscaling process are sharper, while straight lines – especially on distant objects – don’t exhibit as much jaggy aliasing as on 1.0. It’s worth noting that FSR 2.0 once again upscales whichever anti-aliasing setting the game enabled at the time; it doesn’t include its own AA, like DLSS does. In Deathloop's case, I used the Ultra preset for testing, so in any FSR or native shots you're looking at TAA.
An improvement on FSR 1.0 means that FSR 2.0 comes much closer to DLSS on fidelity… just not quite enough to surpass it. In fairness, the difference isn’t often as noticeable as when we zoom in this closely, but you can tell from distant details (like that oil drum and the thin metal grates on the generator) that Nvidia’s tech remains slightly superior. Even if you do need a GeForce RTX card specifically to use it.
In motion, I also noticed less shimmering on objects like staircases and vehicle tracks than I did on FSR 2.0, and that red smoke cloud speaks for itself. It’s weirdly pixelated with FSR 2.0, while DLSS maintains a more natural look.
Still, at least FSR 2.0 can join DLSS in the Better Than Native club. Compared to rendering straight to 4K, FSR 2.0 seems to enhance sharpness and even texture detail. In the comparison above, you can see how the leather and stitching on Colt’s glove, as well as the decaying brick wall, appear just that little bit sharper with FSR 2.0 on its Quality setting.
At 4K, Deathloop’s performance gains from upscaling are unusually modest. FSR 1.0’s Quality setting is the fastest of the bunch, though using the higher-quality FSR 2.0 or DLSS options only added around 10% more FPS than native 4K. On the positive side, AMD card owners will be relieved that the newer version of FSR doesn’t run significantly slower than DLSS, and there’s also some reassurance in knowing that you can select the Quality option and still get near-identical performance to the Balanced option. It’s even with FSR 1.0’s equivalent Ultra Quality setting too, so the visual upgrade doesn’t necessarily come with a performance cost.
So far, you could never call FSR 2.0 a DLSS killer, but it’s a decent enough step forward at 4K. At the more widely used 1440p, I’d say it’s even better, particularly when compared its predecessor.
Check out the whatever-the-hell-vehicle-this-is below; almost everything about it, from the aliasing around the door edges to the detailing on the tracks and even the matte texture of the bodywork, looks better with FSR 2.0. The only reason it looks a bit hazier is due to a passing gust of snowy air.
You can also see how the brick wall, which is closer to the camera, has much more defined edges.
FSR 2.0 still has a pixelly smoke problem at 1440p, and again DLSS’s Quality setting generally enhances Deathloop slightly more. To its credit, FSR 2.0 can actually look even sharper than Quality-level DLSS in certain places – check out the graffiti on the yellow truck – but it’s a harsher, more artificial kind of sharpness.
Ah well. FSR 2.0 still manages to look even better than native at 1440p – or at the very least, sharper. Again it performs its texture-polishing trick on Colt’s gloves, while farther details gain a touch of extra crispness. Then, of course, there’s the performance bonus…
Interestingly, ye olde FSR 1.0 is the worst-performing Deathloop upscaler at 1440p, despite speeding ahead at 4K. What’s more, FSR 2.0 takes its place, edging ahead of DLSS for both their Quality and Balanced settings.
Given how DLSS still looks a little nicer, I’d say that’s still the one to go with if you already own a GeForce RTX GPU. Which, no disrespect to AMD, shouldn’t be a very surprising outcome: RTX cards have machine learning hardware included for the very purpose of making DLSS the ideal upscaler.
However, that’s not to say FSR 2.0 is a failure. Even if it can't take advantage of dedicated hardware, it’s managed to close the quality gap on DLSS significantly, while keeping its platform agnostic quality and even beating the simpler, less intensive FSR 1.0 at 1440p performance. It’s a much-improved bit of resolution trickery, and whenever DLSS isn’t available, I for one won’t mind finding it in a game’s graphics settings instead. Once more than one game starts supporting it, anyway.
