Do the video game increases in performance they claim for this new driver also relate to increased CUDA performance, or are the two not necessarily related?

We have seen some performance increase with the newer CUDA versions, but it can be a crap shoot.
This was run with the 304.xx drivers

M_M:
I just replaced cuda 3.2 with cuda 4.1 dll's in x41g (in app_info.xml). Not sure this is the right way, but it seems working ok for now...
If this is not a right way, then I probably need a new build...
