I am a GNU/Linux user who likes to enjoy single player Unreal Tournament '99 mods natively. Recently, I got a new laptop with Nvidia card. Even though I am using proprietary drivers, I am experiencing serious issues with the game. First of all, the infamous speeding issue presents on Linux as well. I used to avoid that issue by changing the speed of CPU on my old laptop. However, my new laptop has plenty of CPUs, so that's not possible any longer. Instead, I downloaded Linux version UTGLR's OpenGL renderer and applied FrameRateLimit option to the ini file which solved the issue for good. However, the single player mods that I am playing are too darn dark with the OpenGL renderer; for unknown reason the brightness cannot be changed with OpenGL renderer. So, I edited the ini file; changed GameRenderDevice into SDLGLDrv.SDLGLRenderDevice. With that method, as long as I keep UseGammaExtension and UseModulatedGamma options disabled; I can change the brightness. But, unfortunately the framerate cannot be capped when I use that "SDL OpenGL Support" renderer. As far as I understand, it uses SDLGLDrv.so library. Adding FrameRateLimit=100 option under both [SDLGLDrv.SDLGLRenderDevice] and [OpenGLDrv.OpenGLRenderDevice] sections had no effect; the game is still over 200 FPS.
I am convinced that changing brightness is not possible with OpenGL renderer. Is there a way to limit the framerate of "SDL OpenGL Support" renderer? Else; do you know any newer renderers than following renderer for Linux?
