[SOLVED] How can I select the GPU in Unreal?

Community Community & Industry Discussion

I use a Nvidia Quadro P400 and a second GPU Nvidia Quadro RTX 4000. My Monitor is connected to the P400. When I start Unreal the performance is very weak. How can I tell Unreal to use the RTX GPU ? I even tried to start Epic Games launcher with “Render Open GL on:Nvidia Quadro RTX 4000” but same weak performance. I also tried to find any GPU settings inside Unreal - no luck so far.

Seems not to work in each Case. Someone know how to see in Unreal Engine which GPU is used ?

Doesn’t it require the monitor to be connected to the RTX 4000?

I don’t think so.
