Playing Diablo with integer scaling seems to leave it at the original resolution rather than actually scaling it at all. Or is this how it is supposed to look? Since this isn't actually scaling the image I assume not, so any advice on what to do to fix this would be appreciated.

Attached are my current settings, I've tried also running it in exclusive fullscreen and windowed mode, neither seems to help

Well sheeeit, I didn't even think of that.

Yeah that makes sense, I'll try it on a different monitor and see how it goes, thanks so much!
