It works just fine for me. What are the steps that you did?

I use nix so:

1. I installed OBS with all the plugins especially obs-vscapture
2. Run OBS and add Game Capture Source
3. Using lutris I enabled gamescope and changed the game resolution to something higher. I have a 1440p display so I tried 2560x1600 (16:10) to make sure I’m capturing it right.
4. Inside Lutris System Options game options tab I added OBS_VKCAPTURE and set it to 1.
5. When I run the game I can see gamescope is working as it’s projecting a 16:10 game onto my 16:9 screen.
6. Inside OBS I can see the game capture is working and when I select the Game Capture source it shows that it’s a bit too tall for my display.

Should be a similar thing for you, I would try something obvious like 16:10 first so you can get immediate visual feedback and then tweak your settings from there.

did you try this?

you need to capture the game not the gamescope instance.

You can use gamescope to set a higher or lower resolution and it’ll down or up scale it to your screen.

I presume you can use obs or something like that to record the raw footage before scaling.

Have you tried using nix-hardware repo? They have some device specific configs that apply.

If you are, have you tried doing it “raw” in the configs instead?

Also if you are using an AMD CPU, smokeless UMAF has more BIOS options, and you can try enabling/disabling modern standby as well as a LOT of other power options.

I love how casually you just dropped this 😂.

I’m working on something similar but it’s not ready for it’s FOSS release yet.

Feel free to message me if you wanna discuss ideas.

you should use #!/usr/bin/env sh for better compability.

you shouldn’t need the bash if you have a proper shebang
