Besides people trying to run the release with an inadequate system, or a you tube running at the same time.
The game got a bad rap!...I have a earlier edition that I play off line, and I can tell you that it is trouble free. I've said it before but, Steam was much of the early problems with the game. Steam has had many updates to itself since, and that is why my early vershion runs so well, a real sad shame.
