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"

Forcing Unreal to use certain GPU

Hi. I've got an issue with our setup I'm hoping someone could shed some light on.

The set up: I have my workstation connected to two displays. The first is a standard 1920x1200 monitor the second is a 4096x4096 mosaic screen. The small monitor runs the desktop for show control while the second displays the actual presentation. The small monitor has a Quadro K620 powering it while the large display has 2 M6000s.

The issue: Although I can launch Unreal on the larger display, as the small monitor is considered the 'primary' monitor by windows Unreal only runs on the K620 while the M6000s are left idling. This causes poor performance.

Is there a way to force Unreal to use the M6000s?

Thanks

Seamus
