If we have the GLX_SGI_video_sync extension then it's possible to always keep track for the video sync counter each time we call glXSwapBuffers or do a sub stage blit. This then allows us to avoid waiting before issuing a blit if we can see that the counter has already progressed. Also since we expect that glXCopySubBuffer is synchronized to the vblank we don't need to use glFinish () in conjunction with the vblank wait since the vblank wait's only purpose is to add a delay. |
