--- Comment #2 from Shmerl shtetldik@gmail.com --- It's possible it's a game bug, and not limited to Wine. Some report, that it crashes on CPUs with more than 4 cores (my case). See this thread: https://www.gog.com/forum/the_saboteur/game_does_not_start_at_all/post29
I'll test their proposed patch later today to confirm, but it's likely NOTOURBUG case.
