Yeah it hadn't occurred to me to consider the graphics card, LOL! Me, I just have a 3DFX Voodoo 3card, and that seems to serve me just fine with everything, Vue 4 and games included. IMO, they could have totally left out OpenGL from Vue 4, and it wouldn't have bothered me any. I do like it in the Camera viewport though, to get a good idea of the fog and lighting, but that's about it.
