Run installed drm-free steam games without launching steam

[TRDragony]

There are many games which in fact would just run by clicking on the .exe file, but while those games run flawlessly when launched via steam, they usually crash when launched manually, probably because of wrong or broken built-in wine dlls.

I wonder if it's possible to run installed steam games without launching steam, but still with the fixes from this project.

For example I tested with Captain of Industry:

DXVK_HUD=full WINEDLLOVERRIDES="d3d8,d3d9,d3d10core,d3d11,dxgi=n,b" /usr/local/wine-proton/bin/wine64 .steam/steam/steamapps/common/Captain\ of\ Industry/Captain\ of\ Industry.exe

I can see the loading-screen, but then it crashes. Works when started via steam.

We aren't applying any fixes to the apps running in Wine, so I wouldn't worry about missing anything. One potential issue is that reusing the same wineprefix is a bit tricky due to symlinks pointing at ~/.steam/tmp/FreeBSD_Proton dir, which is managed by tools/LSU_FreeBSD_Wine, which naturally doesn't run in your scenario.
