I am running Win2000 on a dual 1800 AMD home built.
My monitor is a ViewSonic P95f+ (19 inch) set for True Color (32 bit) 1024 by 768. The display card is a NVIDIA GeForce4 Ti 4600. NVIDIA Bios ver 4.25.00.27.10

Inside the Window Display Properites the NVIDIA OpenGL Properties menu reads:

Disable support for enhanced CPU instructions sets (box unchecked)
Enable conformant OpenGL texture clamp behavior (box unchecked)
Default color depth(for textures): Setting (Use desktop color depth)
Buffer-flipping mode: Setting (Auto-select)
Vertical sync: Setting (On by default)
