You might want to check and see if the Triple Buffering is set to on by default. Try disabling it (if it isn't already), rebooting, and then see if it's still disabled.
I played a quick match with Gunny and Squidly last night just to test. It's still not as "smooth" as it was prior to the patch - but it's performing pretty decently. I'm still hoping the 'fix' will turn on some extra performance and smooth things out a touch. But then again, when you think everything is fine and aren't paying attention, everything seems fine. But when you are having problems, you are aware of every single odd thing you come across and then some things that might have always been there and you never noticed before. So it's kind of hard to tell. :cheese:
