So. I woud like to use Steam’s proton to play Windows only games on Linux.
At first, i installed the needed Vulkan drivers.
Then, i enabled the proton (Steamplay), with proton 3.16 selected.
When i start a win only game, i get exactly this output:
Game update: AppID 0 "openttd.exe", ProcID 2773, IP 0.0.0.0:0 GameAction [AppID 0, ActionID 1] : LaunchApp changed task to Completed with "" ERROR: ld.so: object '/home/kepsz/.local/share/Steam/ubuntu12_32/gameoverlayrenderer.so' from LD_PRELOAD cannot be preloaded (wrong ELF class: ELFCLASS32): ignored. >>> Adding process 2773 for game ID 33554432 >>> Adding process 2774 for game ID 33554432 /bin/sh: /mnt/store_1/Games/openttd/openttd.exe: cannot execute binary file: Exec format error Game removed: AppID 0 "openttd.exe", ProcID 2773
That “Exec format error” message sounds strange. I’m open to suggestions…
