Doom 3
Finally, let's take a peek at Doom 3, run at 'High' settings using a custom timedemo.Some small but noticeable improvements across the board again here with AA and AF disabled, particularly at 1024x768 where we see a four frames per second increase.
Similar improvements can be found with anti-aliasing and anisotropic filtering enabled, with increases of around 2 FPS at both 1024x768 and 1280x1024.
