I am trying to use atitool with evga precision to adjust my video clock. when i scan for artifacts i get the following error: the video card you selected for overclocking does not seem to be used by windows. visual testing has been disabled. to fix this go to Display Properties, Settings and enable the monitor output of the card. the problem is i cannot find Display Properties, Settings in order to enable the monitor output. Im running windows vista nvidia gforce 9500 gt evga precision 1.4.0 atitools 0.26 i want to optimize my video clock in order to increase my gaming performance edit to add: after some research I have discovered that atitools does not work in vista therefore i want to ask the comunity if there is another program i can use similar to atitools that will let me scan for artifacts.
