I know this is a strange question but is there a way to programmatically (and
dynamically) to do what the __GL_SYNC_TO_VBLANK environment variable does?
I want to sync every n-th frame to VBLANK and let all the other frames
"free-run". Put another way, only the n-th frame will be visualized and all the
other frames will be generating intermediate results. Also, "n" can vary
dynamically as the program is running.
Thanks for your help,
Paul P.
