Okay - you don’t need to switch it on in the game’s settings, it’s just “switched on”. Set an environment variable for the FSR quality that you want, and it’ll appear as one of the ‘resolution options’ in game, and then when you select it, it’ll open at the resolution you select.

So, for me who wants Elden Ring at max settings on my 2560x1440 monitor, which doesn’t quite reach 60fps, and wanting ultra FSR, I’d choose GE8-7 as my ‘run Steam games using this tool’ option, and set my command-line properties to:

WINE_FULLSCREEN_FSR_MODE=ultra mangohud %command%

When the game starts, I’ll see 1970x1108 as one of the screen resolutions that’s offered. When I select it, MangoHud tells me that my fullscreen resolution is actually 2560x1440, and my frame rate is a good bit better than what I’d expect. (MangoHud isn’t essential here, but it’s handy for monitoring resolution and frame rate.)

‘balanced’ is the default, so I should see 1506x847 as an option for absolutely every game that I start with GloriousEggroll, regardless of any other environment variables, and that’ll run it with FSR for me. I don’t need it for most games, and it’s a bad choice for games with lots of text, but it’s always there.

That’s it.

Reference:

thanks for the quick reply! curse my quick fingers, didn’t type it out correctly… I turn on FSR in the game’s settings in Lutris, it’s a switch. then I launch the game, it defaults to 3840x2160. I go “nuh-huh” and switch it in-game to 1920x1080. it switches over and mango says I’m still in 4K, so that should do it?

still, I don’t perceive any difference, does the game have to support FSR in order to work? Elden Ring is way newer than my old games, most are from 8 years ago…?

No probs! And that sounds correct. Doesn’t have to be supported by the game to work, it should be supported by everything. (Trust you’re using the wine-glorious-eggroll-whateveritis option in Lutris, as well?) And yeah, you’re not going to see much difference on ‘old’ games (well, depending on what it is) - if you can already run it at your monitor’s refresh rate, it just has the effect of making everything a little blurrier, it can’t improve the FPS any.

thanks! just ran Rise of the Tomb Raider benchmark, desktop is 2160p, game is set to 1080p, DX11, runner is lutris-GE-Proton8-7-x86_64.

FSR on:

FSR off:

so it’s doing something but I guess I don’t know what to look for. thanks again!
