XP Home, with all of the eye cany off too. I've got a Radeon 9600 Pro 256 MB, which isn't a bad card either, but when it comes to OpenGL and larger scenes it becomes very slow too. That's why I switched from OpenGL to SreeD Software preview to prevent this slowness from happening. I don't even dare to try switch OpenGL on again , but I tried anyway and it's slow). The Radeon Pro series are just home user cards, not pro-cards at all. If you really want to take advantage of OpenGL you're gouig to need a high end business card, not one of these cards geared at home users. But I would suggest switching to SreeD Software preview to see of it's still so slow. I do understand the advantages of OpenGL, but because it comes with such a price tag (slowness) I'll rather not use it.
