Jedi Knight II
Jedi Knight II, Jedi Outcast is an OpenGL game that many have been playing of late. It has greatly improved graphics over its predecessor and it fully supports advanced shaders, as well as very high texture resolutions and effects. There is one demo included in the multi-player section that is good for benchmarking use.
Jedi Knight 2 has the worst CPU bottleneck we have seen in any game of late. Between both resolutions and both cards there is only a .1FPS adjustment across four separate benchmark runs. The CPU rules here.
