Apps and games not using the eGPU

The title is pretty self explanatory.

some apps such as Furmark and some games like doom 2016 don’t use the eGPU for some reason.

Any advice?

Have you tried Graphics Option to specify the High Performance GPU to those apps?

@itsage,

Yes I'm aware of that technique and while most applications respond to it some don't for some reason. Any ideas?

I used another version of windows and nothing changed I can say it’s probably not a windows thing

@sibov97, thanks for the reply but what you said is application specific. I have trouble with bunch of executables that won’t utilize the eGPU and almost none have any sort of in-app option that would allow you to choose the GPU you want.

Here’s a list of stuff that don’t use the GPU(as far as I know):

Furmark

Cinebench

3Dmark

Doom 2016

Minecraft

I’ll update this reply if I find other stuff.

@kian_moiny, Most apps do work when you set them to use the High Performance GPU in Windows Graphics settings. The key is to locate the correct executable file for the app. For example, 3DMark would call up different workload depending on what you want to run. Setting 3DMark exe to High Performance GPU does not work because that's not the workload exe. Take a look at my post above for the location of the right exe for Time Spy and Fire Strike.

@itsage, I've tried but it only worked with futuremark. I have reached to a conclusion that all the programs that are not using eGPU are OpenGL or Vulkan based.

 Any idea what might be happening?

@itsage, can you tell me how you have setup your eGPU and whether you can use Cinebench and Furmark with your eGPU or not? It would be really appreciated.

Figured it out it was because I was running on the Internal Display. Apparently those APIs had problems going through the Intel Controller to the eGPU thus it just used the Intel GPU. Running on the external monitor solved the problem.
