Question Vsync doesn't work ?

[Obsnacks]

No matter what game I play I cannot get my vsync to work. Normally my fps would cap out at 144 with vsync on but now with it on it goes right past that and is not as smooth. I also noticed that in my windows advanced display settings has my fps capped at 143 and it wont change to 144. Please help.

I already used ddu and uninstalled drivers twice. I dont know what the problem is
