.IPs swapinterval=<n>
Minimum interval in displayed frames between to buffer swaps (default: 1).
1 is equivalent to enable VSYNC, 0 to disable VSYNC.
Values < 0 will leave it at the system default.
This will limit the framerate to (horizontal refresh rate / n).
Requires GLX_SGI_swap_control support to work.
With some (most/all?) implementations this only works in fullscreen mode.
