The OpenGL driver for my NVidia RIVA TNT card has extremly poor performance
with the glCopyPixels() operation (copying from the back buffer to the front
buffer)- It takes over a second to copy an entire 800x600 window! On
non-accelerated cards this take less than 30 msecs.
Anyways, until I get some updated drivers or a work-around, I want to know
what it takes to uninstall the ICD/MCD drivers so it will run without any
