Why OpenGL run slowly !
Author
On Window 98, my OpenGL programs running OK. But on Window XP, it very slowly!!! Why ?
Could be anything.
Try giving us more details; like what video card, video driver version, etc. you are using.

I had the same problem until I had updated my video driver and don't use any of microsoft drivers for video as they usually don't support opengl
I've been told that if Open GL can't find a driver, it'll use software rendering as a last resort, so that'd definately explain the problems. Another thing, the drivers that come with XP are basically there just to let you use the device, not have it running at peak performance. ;)

Like the guy before me said, it's because it's running the software emulation of what your hardware (graphics card) normally does.
Download the newest drivers, and it should work quite well.
