I downloaded Terra3d, a simple opengl game where you fly an F14. I did have WinXP, and I ran it on there and the performace was beautiful with all of my opengl games. Now since I have switched back to Win2K, the opengl performace is disgusting! I am running the same video drivers/drivers as I was on XP, but I am only getting 1 or 2 frames now. On XP I got 25 average. Anyone know whats wrong? Please help me.
Sounds like something switched to the software implementation. Try reinstalling the drivers for your video card?
