>Ben: I would hope that people putting in hundreds of hours into a game would want that game played and enjoyed by the widest range of users.
Almost every PC on today's Desktops has an OpenGL - compatible 3d card in them,
I did some searching for the drivers for ATI RADEON 9100 IGP (that's on my most recent XP PC) and found a drivers update & utility package - tried installing and the installation failed. The original installation CD doesn't include openGL drivers.
On my Win ME laptop, there's a SiS 630/730. Yes, it supports OpenGL but the drivers are for XP only!
