Doom 3
Finally, we take a second look at Doom 3, this time at 'High' settings using a custom timedemo.

Both CATALYST 4.11 and 4,12 show some improvement over the 4.10 driver set, particularly at 1024x768 and 1280x1024, but CATALYST 4.12 manages to eke out a small further gain at 1024x768 thanks to the aforementioned driver efficiency improvements.

Any such improvements become far less noticeable with AA and AF enabled, and thus CATALYST 4.11 and 4.12 are basically neck and neck here.
