Diablo 3 and nVidia Optimus(1)Category: Technical SupportMarch-6-2014 6:52 PM PST (6 years ago) Go to Blizzard forum post
So, sometime between last night and today, Diablo 3 stopped using the dedicated GPU on my laptop and, instead, started defaulting to the integrated GPU. I do not get the option to change the preferred graphics processor.

I've reinstalled the drivers 4 times and it keeps defaulting back to the integrated graphics.

Setting the global graphics settings to nVidia doesn't work.
Option to change the preferred for D3 is grayed out.
Can't disable the integrated GPU in the bios

We're still trying to find out what might have caused this. We've updated nothing in the time frame this started happening so it doesn't appear to be anything with the game or Desktop App. The working theory right now is a possible Windows Update or an update for another product is interfering.

Our developers are in contact with Nvidia now discussing the issue. The latest working theory/rumor is an update to the GeForce Experience program may have inadvertently disabled Diablo III from being able to select the High Performance Nvidia adapter. Again, that's just a theory/rumor right now.
