I've had this issue now for awhile. I found that RTSS / Afterburner causes the game to crash at launch the first time I launch it. When I launch it a second time, it launches fine and the OSD comes up and works flawlessly. I've tried delaying the OSD start up (45 seconds), but this doesn't seem to help. In fact delaying it was causing issues with COD IW. I was wondering if anyone else has experienced this? I'm not sure if it's common with Unreal based games or not as I only have this one that I actively play.
