Ok I can’t get either of these features to work on a standalone game build for shipping.
SLi - no matter what mode I run I can never get the second GPU to work. I haven’t tried forcing SLi because in the past that has not worked for me…
Surround - here comes the interesting part. When I play in editor viewport I can span the game on all 3 screens. When I run standalone game and set the resolution to 5760x1080 (native) the game accepts it , but does not show any image on the side monitors. BUT the second GPU seems to be kicking in (or at least it gets HOT )
SOooo can I (or Epic probably I don’t know how to ) make my game run in surround and SLi or does Nvidia have to provide a profile for it ( I have the latest drivers). My rig has 2 gtx 570 in SLI.
