Normal reason for this is that your graphics card is no longer able to run the 3d match engine. Had this with my old Radeon card. For 10.1 patch, I could use older Radeon drivers to make it work. But from 10.2 patch, nothing will work. SI ain't fixing it either, but always worth going and complaining.
Try latest drivers for your card (if not installed already) just to doublecheck problem hasn't been accidentally fixed by card maker.
