Need help understanding the Wine AMD FSR hack
Avehicle7887 7 Dec, 2021
Has anyone tried FSR and has experience how it works? I could use some guidance

The story: I have a lower end PC attached to a 1440p monitor, the GPU can't handle the native resolution.

I can confirm the feature is enabled in my Wine setup (WINE_FULLSCREEN_FSR=1) however it only makes an effect if the game is running at 1280x720 (720p) and desktop is set to 2560x1440. Has no effect if I set the game at any other resolution.

Is this normal or am I missing something?

Might be specific game issue? maybe game is doing scaling by itself?

it should work for every resolution lower than your monitor native. Obviously the higher(closer to monitor native) the resolution the less performance is to be gained.

So I did some research and have tried setting the games at the resolutions as per this chart: https://www.androidauthority.com/wp-content/uploads/2021/06/AMD-FSR-quality-and-scaling-details.jpg


FSR now works on all the resolutions tested (I never tried these resolutions before so most likely that was an oopsie on my end). The last remaining issue now is that only 1280x720 scales to my entire screen. The other resolutions look like this:

Any leads?

EDIT: Turns out the borders were being caused by "WINE_FULLSCREEN_INTEGER_SCALING=1", it needs to be a "0" :)

Well this was fun

I'm in your exact situation, but I'm using Proton. How can I use FSR?

EDIT: I digged a bit more, seems that I must use Proton GE
