      Description

      The recommended way to turn off vsync is to use the GLX_SGI_swap_control extension and the glXSwapIntervalSGI function. Our code already does that, but for some reason we remain vsync-locked on Ubuntu.

      Another way to turn it off is to use the __GL_SYNC_TO_VBLANK=0 environment variable, which does work but requires user intervention so it can't be controlled from our command line switch.
