There was a patch released....I think?
Also, I remember some discussion about anti-aliasing turned on causing graphic issues?
Honestly, everybody kinda gave up on that title awhile back.
There was random discussions about trying to get them to release the source code, so EECH could get a graphics overhaul. But it went nowhere.
Your best bet would be to PM Colonel_Kurtz.
He had as much knowledge of the problems with that title, as anyone I can remember.
