I’m on Fedora 42, running GNOME 48 (Wayland) with an RTX 4050 GPU. Trying to play Red Dead Redemption 2 via Steam using Proton Experimental.

The game is stuck in borderless windowed mode. I can play just fine.

There’s no <WindowMode> tag in the system.xml.

I only changed the framerate in system.xml to 144, which works.

Tried -fullscreen in Steam launch options — does nothing.

Can’t switch to fullscreen from in-game either, there’s no option.

Not using Gamescope. Didn’t touch anything else. No VSync changes. No other launch flags.

Is there any way to force this game into actual fullscreen under Proton?

Edit: System.xml keeps updating so I’m using following launch options now:

DXVK_FRAME_RATE=144 %command% -height 1080 -width 1920 -refresh 144

Edit: I installed x11 and the game is now working fine. Also had to enable vsync to prevent screen tearing.

    The first things I would try would be:

    • Using an X11 desktop session instead of Wayland.
    • Using a different Proton version.
    • Making sure those width/height/refresh command line options are valid and match my monitor’s native specs. (By the way, DXVK_FRAME_RATE is for Direct3D 8/9/10/11 games running with DXVK, and doesn’t set the display’s refresh rate in any case. It won’t help you with this problem.)

    After that, I would start reading the discussion here:

    This comment seems relevant, as does this one. There are plenty more.

    is there a reason not to use gamescope? Have you tried proton forks like ge or tkg? also have you checked protondb for anyone having the same problem?

      I tried but the launcher crashes … Managed to play the game with x11. But the graphics and audio quality is significantly worse.

    I had this problem with windows a while ago and I believe in the graphics settings I was able to change it from “Vulkan” to directX. I don’t know anything about Linux, but if you have a comparable setting you can change you might be try that?

    Are you using Gnome? (Workstation)

    Also, though unrelated to your issue, DXVK_FRAME_RATE only works with DXVK (DirectX 11). RDR2 will use VKD3D (DirectX 12) or Vulkan natively.

      Yeah. I’m using Gnome. DXVK works with Vulkan.

        That’s not the point, dxvk isn’t gonna get used at all if the game is running dx12 or native vulkan.
