- 1. In the Blizzard App, select the Options drop down in the Diablo III tab and select Show in Explorer
2. Right-click on Diablo III.exe and select Properties
3. Go to the Compatibility tab and check the box ‘Disable fullscreen optimizations’
4. Press Apply and OK
Otherwise, let's try closing down background applications and see if that may help.
