Hello, I have a XFX Radeon 6850 video card ( running on Windows 7) and Vertical Sync doesn't work and it's most notable when i play videos ( movies or on YouTube), the image get's distorted like the Vsync isn't activated. From the AMD Video card settings i have set Vertical sync to be ALLWAYS ON, but it doesn't work. I was wondering could it be because of some setting in Windows or can you set Vsync from some Windows desktop settings? I can provide more details, i was to vague. Thank you.
