ive tried a different card. the original card i used had the same problem, but it was a lower end card. my monitor must be defective when it comes to that then cause it wont go over 60 hz refresh rate at the resolution i use and its supposed to run at 85 hz. i truthfully dont even know what difference it would make, but if my monitor and card support it i would rather use the higher setting.
