I don't know how much impact it can have in this case, but I believe the recommended approach is to start wine after cd to the steam.exe folder On the other hand, the messages that look more suspicious are the ones regarding Direct3D: > > err:wgl:X11DRV_WineGL_InitOpenglInfo couldn't initialize OpenGL, expect problems > err:d3d_caps:WineD3D_CreateFakeGLContext Can't find a suitable iPixelFormat. It seems something in your driver or X11 might be mis-configured.
