Search help

  • Simple searches use one or more words. Separate the words with spaces (cat dog) to search cat,dog or both. Separate the words with plus signs (cat +dog) to search for items that may contain cat but must contain dog.
  • You can further refine your search on the search results page, where you can search by keywords, author, topic. These can be combined with each other. Examples
    • cat dog --matches anything with cat,dog or both
    • cat +dog --searches for cat +dog where dog is a mandatory term
    • cat -dog -- searches for cat excluding any result containing dog
    • [cats] —will restrict your search to results with topic named "cats"
    • [cats] [dogs] —will restrict your search to results with both topics, "cats", and "dogs"

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.

Product Version: UE 4.12

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
