I noticed prepar3d is using only one of my graphic cards and there is no profile for it in Nvidia panel so tried setting it to alternate frame rendering 2 and it seems to work with both cards being used, but not sure if it helps much. What are other SLI users doing for this?
I wonder if it has to do with being a 32bit program?
Does FSX use SLI?

Yes FSX has a Nvidia profile and uses SLI effectively. I just tested both at a large airport and in windowed mode so I could see Afterburner graph for each video card and gpu usage is higher in FSX than Prepar3d which is good for FSX but means Prepar3d has to rely more on your cpu.
I don't think it is because of 32 bit as many 32 bit games are set up with SLI profiles.
I did find out you can't run FSX and Prepar3d at the same time though.
Yep, found that out too. I guess certain core programs in each sim are duplicates that refuse to run at once in Windows.Originally Posted by TeiscoDelRay
