I just got done playing what was supposed to be the November 2nd patch, and I must say that the performance has gotten a good bit better. first off, I tried lowest settings, which it looks as if the minimums and stutters have gotten better, then I tried ultra settings, which ran at about 30-45 as compared to the previous 11-25 I was getting (all on grain elevator). The next step is to create some benchmarks of a level run-through, revert to the old patch, benchmark that one, and I'll post some results for you guys.
One last thing to Yoshiro; I live about 10 minutes from your offices in Roswell, would it help if you guys could use my rig for a more diverse testbed in order to improve performance on amd crossfire machines?
