Can you do a measurement for me?
run in quake console:
timedemo demo1.dem
using:
aga
your 100MHz 060
software rendering.
320x256 processor chunky to planar processing
1x1 pixels
I´d like to know if it is double the framerate of my 50MHz 060

My score is 6.40 fps.
Sure seems like it is very cpu bound because at 2x2 pixels I get 8.8fps.
