I'm experiencing missing (black) textures in games, geometry not being updated in the perspective view in Rhino, and generally strange behaviour with software using DirectX. The .NET framework and DirectX are up to date.
Am I correct in assuming that Parallels can't recognize the iMac's ATI Radeon HD 5750, and that installing drivers for that card will not help? I have tried installing ATI's Catalyst Control Center anyway, but to no avail. (Install completes, but the install destination is empty and nothing appears in the system tray.)
Is there anything else I can do?
