Here's a screenshot showing v-sync, or at least I think this is it. I once downloaded the omega drivers and they caused my task bar to completely disappear and I could not get it back. I had no option but to use GoBack to undo it.

The setting I have is "application preference" which is the default, so, does that mean I can manually set it with a script in 3DGS? If so, what variable is it that I need to use? I only need it for my 2D game and not my 3D game.
