I've made some tests and on my system here at work and I've also worst
Average update time: 25ms
My system is anyway older than yours:
Matrox G400 (AGP 1x for MB limitations)
1280x1024 24bpp (32 real)
Anyway with some counts the amount of time is not that strange...
800x600x4 = 1920000
1920000 x 50 = 96000000
So you need 96MB/sec of bandwidth to have a frame each 20ms (50fps), that's
a lot of datas, since you have also to read them from memory and cache
don't help in this kind of operations...
I suggest you to try to make the game run in 16bit, so you could have
almost double framerates and the quality will be almost equal.
