Default Re: Incorrect or no vsync on GT240

For VDPAU, to guarantee tear-free presentation on all monitors at once, you need to make sure that VDPAU is using the overlay-based presentation queue and not the blit-based presentation queue. See the Appendix H (VDPAU) in the README for details on when each is used. When in blit mode, if using TwinView, sync-to-vblank can only work on one monitor at a time. You can set an environment variable to select which. Again, this is described in more detail in the README.
