Wayland system scaling and game resolution

I recently started using Manjaro again and have been doing a lot of tinkering with Wayland to make it work properly with my Nvidia RTX 3080. My display settings are set to system scaling at 150% because everything being the right size is more important to me than blur generally. However in some games, specifically Counter Strike 2, the highest resolution option is 2560x1440 on my 4k monitor. I have seen people mention this is because of the fractional scaling, but I was wondering if there is a way to fix this?

It’s probably running in borderless window mode. Try running it with -fullscreen option.

Unfortunately didn’t help, changing the setting manually in game without the launch option also doesn’t help.

The only other thing I can suggest is try running it in gamescope. Install gamescope from the Manjaro repository and then the Steam launch command would be

gamescope -w 3840 -h 2160 -f -- %command%

For Nvidia make sure you have the nvidia-drm.modeset=1 kernel parameter set. More details at GitHub - ValveSoftware/gamescope: SteamOS session compositing window manager
