I recently upgraded from .63 to the latest and now I wish I hadn't. I have an Athlon2300 or so in my cab and it's just too dang slow to run any of the new stuff. If your cab is tricked out with the latest CPU then maybe it is worth your time. I also have not gotten on the controls.cfg bandwagon so a lot of my games button configs were royally screwed up when I updated, and I just haven't made the time to reset them all. I think I finally need to go the cfg route so this doesn't happen again.
