Cant launch Direct3D 11 games on Wayland with Proton 5.13 to 6.3 #4816
Comments
I was having problems getting Twilight Struggle, a Unity game, running on Steam/Proton Experimental with Ubuntu 21.04. With Ubuntu 20.10 I had been using PROTON_USE_WINED3D11=1 %command% as the configuration string. That worked with Ubuntu 21.04 for a period of time after installation because I appended --xwayland to the configuration string. Then it stopped working under both XWayland and XOrg. Reading this issue I found that WINEDLLOVERRIDES=dxgi=n %command% allows the game to run under XOrg and adding --xwayland works under XWayland but at a much lower frame rate, like 1 FPS. |

Looking at the diagnostics information, there's some kind of snafu with XCB connections and Steam Linux Runtime interaction with Flatpak. (https://gist.github.com/Ristovski/016710a5e5ccb6b32a2e3cc93caf0eb7#file-gistfile1-txt-L3723) Please open a new issue report in https://github.com/ValveSoftware/steam-runtime/ focusing on that XCB detail. |
