Nay, I have addded opengl sdl to my make.conf and synced and emerged. Did I misse some steps?
Those old quake1 alike games works...
Hmm guess I have to re-emerge video driver too, gonna give it a try tonight, thank you man.
This is confusing, I used to think I won't have GL extensions in Nvidia installed if I missed the opengl flag.But after SI installation I checked my NVidia extensions and XGL is there and confirmed by a successful UT2004 retail install. Then I assumed I don't have to re-emerge nvidia drivers. Seems that I totally lost the point how emerge works:(
