Back to the original thread (OpenGL on Vista), I've been reading a lot about Vista to try and decide if we want to upgrade our work PCs (we aren't for now) and OGL was an issue for us. Now in my rather limited knowledge, what I understand is that Vista does support OGL but under Direct X which greatly slows down performance. But most graphics apps use OGL from the video card not from the OS. While some (all?) apps may need to update the OGL part of thier apps, video card OGL should be about the same under Vista as XP. I have no idea how this effects Poser. This is just the impression I got and subject to correction:-) Best; Dan
