Performance degradation with WPA hashes and Nvidia 331.20

[burst2]

As driver developers change things, it can impact performance. If there was no reason for the upgrade other than to say you are using the latest driver, I would revert back to 319.60.

Certainly. The problem is I'm stuck with the 3.11.x kernel, as the good old nvidia 319 don't like the new kernels.
Anyway. Just wanted to report it.
