I tried same thing here.
I got 31 FPS in 640x480, 18 in 800x600 for the test I did.
An 800x600 screen has 1.5625 times the amount of pixels a 640x480 screen has.
18*1.1565 = 28.125
That's pretty close to the projected 31 FPS.. Then you also have to take into account that higher resolution means more memory bandwidth used by the DAC as well, stealing performance from 3D.
Your numbers don't quite fit in this formula, but maybe your 800x600 mode is in a much higher refresh rate than your 640x480 mode?
