I think it may have something to do with the following lines: [Engine.Engine]^M GameRenderDevice=SDLGLDrv.SDLGLRenderDevice WindowedRenderDevice=SDLGLDrv.SDLGLRenderDevice RenderDevice=SDLGLDrv.SDLGLRenderDevice
In .loki/ut/System/UnrealTournament.ini Also look at the various options under [SDLGLDrv.SDLGLRenderDevice]
