Tested it with any tool/software/game I have installed on my laptop. All works nice. As soon as I startup Midair, while my laptop is plugged in (loading cable, not running on accu), the laptop starts to stutter: the plug in shows off/on/off/on/off/on and the whole system lags. As soon as I quit Midair, all works fine again - the plug in shows that my laptop does not run on accu. I guess it has to do with UE4 (unftly I have no other UE4 game to test) or with the game code and maybe memory allocated - but no idea why this would be caused.
