When looking at the MDK2 scores, we see CPU limitation all the way across in 16-bit, though there was the slightest drop off at 1280x1024. Moving to 32-bit color, the numbers drop by nearly 20 fps at 1024x768, and then by another 20 more at 1280x1024.

Breakneck proved to be almost entirely CPU limited. If we look closely, running through 16-bit we see that there is very little drop all of the way up to 1280x1024. In 32-bit we see a drop starting at 1024x768, but even at 1280x1024, frame-rates were more than high enough.

Expendable performance was generally very good. We see that even on a faster CPU there is still a good bit of CPU limitation. At 1280x1024, there is a start of a fill-rate limitation in 16-bit. In 32-bit color, we see a bandwidth limitation start to cut frame rates a little at 1024x768 and they drop further as we get to 1280x1024.
