AMD as an Example

From Top to Bottom at High

Notes

At both 1024x768 and 1600x1200, High Quality paves the way for a higher average frames per second score. The lower resolution continues demonstrating CPU scaling as the Athlon 64 processors run to their respective limits. Conversely, up at 1600x1200, Quake 4 seems to be limited by graphics performance, albeit at ceiling roughly 10 to 15 frames higher than Ultra Quality.
