I don't notice any improvement moving from the beta to the full release. In fact I've actually noticed some game slowdowns on busy/large lots since upgrading. I say if it aint broke don't fix it.
Yeah, I did not try the Beta for exactly the same reason, since I had not suffered the problem nearly as often after replacing the broken heat sink bracket for my CPU. I had also altered my gameplay settings and habits around some perceived superstitions about why the game was failing, and combined I had gone for several months without an issue.
I too, notice a bit of lag that was not there previously, but it may be the fact that I have been running now with all graphics settings and features at the highest levels, including the 'smooth edges', which may be the biggest contributor to the problem. I can't really recall ever trying to run the game that way before.
Once I am satisfied that the new drivers have banished the issue, I may try to tweak the settings down to see if the lag can be reduced significantly, but not just yet.
Is it necessary to update this if you're still using the beta and not having any problems? With my GeForce 6600, the game would freeze completely and not even go to the blue screen, but it only started doing that when I updated my drivers last time. Everything's been fine with the beta driver, even with all the settings turned up like yours are, so I don't want to mess with it again unless I have to.
Well, if it ain't broke...I don't personally see much reason to upgrade to the final release 'just because'. My posting this here mostly for others, who like myself, were perhaps not having desperate problems and were waiting to see if the fix might be for real before tampering with the drivers, yet again. The official release carries the same version number as the Beta, so I don't think there were significant changes made, if any. I noticed some people having issues with other programs, though, and I suppose it is possible that some programs might barf on drivers not WHQL certified, I don't know. If you have issues with not-TS2 programs you might want to upgrade.
