Jedi Knight II: Jedi Outcast
JKII is another OpenGL title based on the Quake3 engine.

As with RtCW, the later drivers appear to have a lower performance than the earlier driver; however, on this occasion when the game becomes more fill-rate limited this is turned around into a performance increase.
In this instance the average FPS is well above 60 FPS at 1024x768 and just above 30 FPS at 1600x1200.

| % Difference | 640x480 | 800x600 | 1024x768 | 1280x960 | 1600x1200 |

Interestingly, in this instance adding 2X Anisotropic filtering hardly reduces the performance at all. It may be that JKII is predominantly single texturing and 2X Trilinear Anisotropic filtering is fitting the 4x4 texel sampling units quite neatly.
FAA is accounting for a performance penalty, albeit a worst case of 25% drop. Adding 2X Anisotropic filtering on top of FAA doesn't amount to any further decrease and with both these the title remains above 60FPS at 1024x768 and over 30 FPS at 1600x1200.
