We tested to see how well AMD’s FidelityFX Super Resolution really works
AMD FidelityFX Super Resolution — shortened down to “FSR” to not be such a mouthful — was finally unveiled at Computex 2021. It’s the long-awaited answer to NVIDIA’s own marvel, DLSS, which leverages artificial intelligence and neural networks to make PC games look and run better.
Now that AMD’s FSR has launched, we can put it to the test to see how well it works in the games it’s actually compatible with.
What is AMD FidelityFX Super Resolution?
I wrote a much more thorough FidelityFX Super Resolution vs. NVIDIA DLSS article explaining how each works. But at the end of the day, both technologies take a frame rendered at a lower-than-native resolution, upscale it, and sharpen it to look as close to the original as possible.
One of the biggest differences is compatible hardware. NVIDIA’s DLSS requires RTX GPUs — which are some of the best graphics cards — with dedicated Tensor cores. AMD’s FSR, which doesn’t need any specialized hardware, works on Radeon RX 6000, RX 5000, RX 500, RX Vega, and some RX 400 cards. It also works with NVIDIA hardware, going all the way back to GTX 10-series GPUs that don’t work with DLSS.
What games work with AMD FSR?

- Godfall
- The Riftbreaker
- Terminator: Resistance
- Kingshunt
- Evil Genius 2: World Domination
- 22 Racing Series
- Anno 1800
That list is expected to grow by at least 12 in the coming months, with huge titles like Far Cry 6, Resident Evil Village, and MYST gaining support. There are also a ton of development studios already on board, so we expect FSR to come to plenty more games in the future.
How much of a difference does AMD FSR make?
To see how much of a difference AMD’s FSR can make, I tested a few of the supported games using an AMD Radeon RX 6800 GPU, AMD Ryzen 7 5800X CPU, 32GB of DDR4-3200MHz RAM, and an MSI MAG B550 Tomahawk motherboard.
FSR has four different quality modes: Performance, Balanced, Quality, and Ultra Quality. To enable FSR, all you need to do is select one of these presets from the in-game menu. It’s that easy. Depending on the resolution you’re looking to play at, the game will be rendered at a lower resolution before being upscaled. That’s where the performance boost comes into play, since your hardware doesn’t have to actually render frames at, say, 4K. AMD’s GPUOpen website has a chart that shows exact numbers.

Using Ultra Quality, games look almost as good as with FSR turned off, but visual degradation gets worse as you move down toward Performance mode. It’s harder to see with still images, but motion blur is particularly bad in Performance mode. It’s still certainly playable, and anyone with low-end hardware is no doubt going to take the higher frame rates with the blur. You can see below the differences in image quality in Godfall.
Now let’s take a look at frame rates in graph form, with UHD (4K) in purple and QHD (1440p) in gold. As you can see in the graphs below, AMD’s FSR makes an enormous difference in performance.
It’s clear that FSR can make a huge performance difference in supported games. And unlike NVIDIA’s DLSS, FSR is available in far more GPUs thanks to it not requiring dedicated cores. FSR even works on some of NVIDIA’s GPUs that don’t support DLSS, which is huge.
My impression is that DLSS still does a better job in terms of delivering overall image quality with boosted FPS, and due to its maturity it’s available in many more games. Once DLSS and FSR start becoming available in the same games we will be able to have a much closer look at how they compare. The bottom line remains that AMD’s FSR is a huge boon to almost everyone with a semi-modern GPU, and we hope to see it in plenty more games soon.
Windows 11: Release date, price, and everything you need to know
Microsoft’s current version of Windows on the market is Windows 10, which would imply that one day a Windows 11 could launch, right? Microsoft is expected to ship a large update for Windows later this year, codenamed Sun Valley, that is said to bring with it a brand new user experience with a new Start menu, sounds, iconography, and much more.
