Question / Help Dedicate a GPU to OBS?

[baker]

So I have two R9 290's and for some reason crossfire doesn't work on Arma 3, but I am curious if I can dedicate a GPU to OBS so my game is more stable? I Run dual monitors if that's help.

You have to run OBS on the same GPU that the game runs on or else OBS won't be able to capture it.
