OpenGL?

What's the dealie with OpenGL in Windows Vista? I notice some games work flawlessly. But some just don't work (Quake4), must use Software (GZDoom Doom port) or play like a slideshow (Doom Legacy Doom port). I'd like to know what MS has done to it!

It depends on what version you installed If youre using a current version it could be processing through Direct3D which will slow it down. You'll need to get a Windows Vista ICD driver for it. When and where this'll be available Im not sure.

I have the same issue when running any of my OpenGL games. The software vendors say that it should work if we have the latest drivers for our V-Cards. I'll have to do more research on this. I'll post my findings here.. if there are any.
