Title: FSR via Proton

Hello,

I use a Nvidia GTX 970 (driver 470.103.01 / Xubuntu 20.4). For Nier: Automata and Elite: Dangerous I have set the following launch option in Steam:
WINE_FULLSCREEN_FSR=1 %command%
Tested with the current Proton 7. I have a monitor with a native resolution of 1200p and the games are set to 800p. Unfortunately, I don't see any effect. Not even if I set
WINE_FULLSCREEN_FSR_STRENGTH=2
which is supposed to be the maximum. Am I doing anything obviously wrong? Have any of you ever tested this? With which graphics card and resolution? Maybe one of you can enlighten me and also name games where it worked for you.

What is also not entirely clear to me is to what extent this is really driver/GPU-independent. According to my understanding, it is based on compute shaders and they run on the GPU.

regards
Oliver

You'll need a custom version of Proton for this, probably the best and widely used being proton-ge-custom:
https://github.com/GloriousEggroll/proton-ge-custom
This is the latest release: https://github.com/GloriousEggroll/proton-ge-custom/releases/tag/7.2-GE-2

And here are the instruction (listed on the main page):
Download a release from the Releases page.
Create a ~/.steam/root/compatibilitytools.d directory if it does not exist.
Extract the release tarball into ~/.steam/root/compatibilitytools.d/.
tar -xf Proton-VERSION.tar.gz -C ~/.steam/root/compatibilitytools.d/
Restart Steam.
Enable proton-ge-custom.
Alternatively you could use ProtonUp-Qt to manage you Proton version:

Thank you very much! In Nier: Automata I see a difference with it. Especially with the text. But regardless of that: Can you see somewhere if the option is really active?

In any case, thanks again!

If you use Mangohud (Goverlay) you can enable show resolution on it. It should show your screen resolution there while your game is set to lower. This should indicated it is working, unless some other scaling is in place.

I see. Thank you for the hint. I have also taken comparison pictures and with these the effect is very clear to see. The funny thing is that the blurring of the upscale doesn't bother me for the game graphics. My brain just filters it out. It's the blurred in-game fonts that bothers me, and FSR works wonders here.
