switched to a newer blit function in the driver for NV11 and higher (below does not support it). Benchmarking shows this blit has about the same speed as the old one. The reason for switching is the fact that this new function supports auto_sync_to_retrace. That should counteract the drop in fps for synced swaps (3D) a bit.
