If you've come across an issue where Overwolf itself and apps installed in it look botched and grainy (check out some examples below), this is most likely due to a setting called "Hardware Acceleration".

This can be fixed very easily by disabling the Hardware Acceleration option in Overwolf, and we've got you all set with the HardwareAccelerationOverwolf.reg file attached to the bottom of this article, so all you need to do is just:

  1. Download it
  2. Run it 
  3. Restart Overwolf
