Like most modern games, Diablo IV will allow you change the framerate (FPS) the game runs at through it’s settings menu.
So if you are noticing that when you tab out of the game, it runs at a significantly lower framerate, this guide will break down how to change both FPS settings in Diablo IV.
Diablo IV is available on PC, PlayStation 4, PlayStation 5, Xbox Series X, and Xbox One.
Additionally, if Diablo IV is taxing your PC (especially while fighting World Bosses), you can manually assign a framerate ideal for your rig through this option.
