Yes there is, because starting with the 163.44 release, NVidia has made some rather large advancements in the performance of these drivers. The 163.44's were released as a "Bioshock Performance Driver" and as such, seemed to boost performance across the whole spectrum.
Aside from that particular driver, the 156.55's from Laptopvideo2go.com are a very solid performer also. These drivers are the FIRST Vista driver to be released with FULL mobile support. By that I mean they support Powermizer features that the previous desktop modded drivers just couldn't deliver. These are the drivers I am using and testing currently, and we hope to deliver a MobileForce product for this set in the very near future.
So yes, in short, you should probably update your drivers and give one of the newer sets a shot. You should see a very nice improvement.
