Does your Vsync actually work when you set it in drivers?
Mine doesn't.
I have to use D3Doverider to force vsync.
Don't know, don't use vsync ever. It creates too much input lag and after well over a decade they(Nvidia/AMD/Anyone) still have not came up with a real solution to it.
Well Triple buffering is a solution, you can use 3rd party software to force it.
