I found out the other day that Arma 3 and XSplit do not get along. Apparently opening XSplit whilst Arma 3 is running will crash the game, and running XSplit and attempting to launch Arma 3 will throw up a "Handle Is Invalid" error.
It seems to occur exclusively with XSplit and as Battleye attempts to launch, then prompts me to launch the game w/o Battleye. OBS seems to work fine, so in theory I could just record footage with that, but I'm a lot more comfortable using XSplit. Does anyone have any thoughts on how to fix this? Google has been little-to-no help here, most of the inquiries on the Arma 3 Community Hub on Steam have gone unanswered.
