I also have a n 8600M GT (on an Acer Aspire 5920).
Recently I upgraded to 185.81, and my screen suffers from some occasional flickering on the bottom half. Later, I upgraded to 186.13, but it had the same problem. I even have a "dead" pixel now, although I don't know whether this has something to do with the flickering...
So I downgraded to 185.20 again, and everything works fine now.
I also noticed that GTA4 crashes and/or becomes visually messed up since I upgraded. I don't know since which driver version this problem occured. Didn't try GTA4 since reinstalling 185.20.
For performance: overall it seems that when I upgrade, the performance DECREASES. I suspect, although this is just a wild guess, that this might have something to do with the installation of PhysX. I de-installed it and now everything seems to run slightly smoother. Didn't test thoroughly though. So a question: is it good to install PhysX on a 8600M GT or does this card simply not support it?
Does anyone have the same problems/issues as I have?
Bottom line: I also have no clue what the best driver is, although I suspect it isn't necessarily the newest.
