Jedi Knight II
Jedi Knight II, Jedi Outcast is an OpenGL game that many have been waiting for. It has much improved graphics over its predecessor. 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.
DX7 games gives both the I9xx chipsets and the onboard I915G graphics a bit of a boost as memory latencies aren't an issue with this version.
