Well, on my Xubuntu machine it runs just as well as the Windows version (slightly worse performance aside, that's probably due to the nvidia nouveau driver). No crashes or anything in the 3 hours I played today.
There was a completely different WTF moment, though: Windows and Linux version seem to read save games completely different, which resulted in a completely normal save game on Linux being read by the Windows version as a game with ridiculous values across factors like crime, pollution, etc. I'll attach a screenshot and I'll mantis it.
