Running 1024x768 full screen, I get between 1 (heh) and 15 FPS on my system. Oh dear. At 640x480 it’s more like 3-30 FPS, mainly around the 15 mark. When there is action on the screen, it is really slow, sometimes less than 1 FPS, but it doesn’t seem to register below 1.

My machine is an Athlon 1.333 with Geforce 2 Ultra, 512MB RAM. Not exactly brilliant these days but still...

Perhaps it should be measured in seconds per frame?
