Robert,I am not even running with vsync, what does vsync do? Also how do I trun it off and on?Thanks,
vsync is the syncronization of the swap buffers with the screen refresh. How to turn it on/off depends entirely on the platform and drivers you are using.
Under Linux you can use nvidia-settings tool, click on the "OpenGL Setting" option, then toggle on the "Sync to VBlank" option.
Alternatively, and this is what I do, is enable it via an env var: To switch on vsync:
export __GL_SYNC_TO_VBLANK=1
To switch off
export __GL_SYNC_TO_VBLANK=0
I just stick it in my .bashrc.
Robert.
