WOW!!! That that really made a difference! I'm running 14.04 LTS on an Acer c720 chromebook (so celeron with intel HD graphics) When I ran the demo I had to use the command 64 and it ran fine. I bought the game after the asteroid missions came out on steam The game has been crashing after a single mission. After putting that command into steam I ran a solid hour or 2 and did a bunch of missions...
