I have installed a new VisionTek Radeon HD 7850oc ed. When trying to play games such as: Farcry 3, GW2, Civalry Midieval Warfare, Saints Row 3, Dayz, and Warz the in game graphics begin to artifact and shadows begin to flicker. I have tried troubleshooting low to high quality settings along with dropping the clock speeds. I have read on several different forums that it is most likely caused by the amd drivers. In response I rolled back drivers and still no fix only minor changed in how many artifacts/flickers. Along with the graphical errors every now and again I will get a "Display driver has stopped responnding and has recovered"
