i want to show a software rendered buffer on screen. i tried glTexImage2d which is fast on newer machines but on a 433MHz pc with an Ati Rage Fury Pro it takes more than half of my frame rate (250 fps reduced to 100 with a 256x256 32bit buffer). Is there a faster way, especially for older computers?

1) prolly not.
2) fps is NOT linear. 250fps to 100fps is less of a drop than 100fps to 60fps.
Don't worry about it till you start going out of frame(60 or 30, depending on the game type)
