I haven't had the issue personally, nor heard anything on it, but then again, I've only managed a 200mhz fsb, so maybe the 235mhz was too much for the game to handle on your system...or the planets were all aligned just right..oh, ::hits switch::, all better!
Nope, haven't had the problem. But did you get the patch for ATI cards? There is a patch out specifically for certain ATI cards and driver versions because a bunch of people were having this problem. Check the website for downloads.
