Decent performance gain on Fermis. Older GPUs are seeing a slowdown over Cuda 3.2, which has been reported & apparently reproduced by nVidia. I was hoping they'd fix that by release, as it means will probably have to support 2 builds next installer.

Was that cuda 3.2 apps on the beta driver?
Have you compiled a cuda 4.1 app to see how it goes?

It was Cuda41rc2 and Cuda41 apps that were quite a bit slower than Cuda32 apps on Pre-Fermi GPUs (like my 9800GTX+) with the Cuda41 drivers, Fermi's have a performance increase with Cuda41rc2 and Cuda41 apps,

I see NVidia promises some major improvements for several games, but how is the CUDA processing with these drivers?
I'd like to know before I convert my main gaming rig (which crunches WU's when not gaming) to these new drivers...
Regards,
Patrick.
