On Notebook: since the hotfix 3 is online, the game will alltimes stuttering after gamestart. The video, the menue... I didn't try to start a match. On my main-pc: I tried installing and start the game first time today. If I used the same start command from my notebook, the game was crashing and didn't start. Without any commands I could start the game, watch the video without stuttering but after a few min, the game is freezing in a mission video or in the menue...

gamemoderun %command% I had the same issues without a start command.
