I have been writing short GL apps at work and at home. The work machine is an ~800mHZ Pentium III with a 16mb Rage 128 card. At home I use a 1.4gHZ Pentium 4 with a 64mb GeForce2 Ultra. The projects I build at work run fine, however, when I port them to the home machine, as both source and executable, they seem to be running at less than half the framerate. I’d expect the exact opposite to happen, but nonetheless, the app crawls on the faster machine. I am not using any OpenGL extensions. I ran the same app on a friend’s GeForce2 machine and got the same results, so I’m pretty sure it’s not an OS/Hardware problem. Do I need to specifically write code for the GeForce in order to get standard performance? Has anyone else had a problem like this?
