Single process - Mutilple windows - Multiple graphic adapters

Hi everyone,

My question is quite simple, the answer may not be.

Is it possible to run an unique instance of UE4, with multiple windows attached to it, each of them using different graphic adapter ?

I know it’s possible to open multiple window and render into it, but I wonder if it’s possible to tell the engine:

  • window1 will use the graphicadapter1 for rendering
  • window2 will use the graphicadapter2 for rendering
  • windowX will use the graphicadapterX for rendering

Best regards.

If you are using the editor and not a packaged build then youo can change the r.GraphicsAdapter in the ConsoleVariables.ini file. You’ll have to uncomment it and then set it to whichever gpu you want to use
