Interesting, I notice the nvidia driver version being reported here is the same as it was on the other bug:

NVRM version: NVIDIA UNIX x86 Kernel Module 285.05.33 Thu Jan 19 15:24:04 PST 2012

and that's quite old. I wonder if your installation got corrupted?

Anyway, this is the cause of your performance loss. From Xorg.0.log it indicates this old nvidia is not compatible with the xserver, so is running in some sort of compatibility mode:

[ 625.647] (WW) NVIDIA: This server has an unsupported input driver ABI version (have 16.0, need < 14.0). The driver will continue to load, but may behave strangely.
[ 626.504] (II) NVIDIA dlloader X Driver 285.05.33 Thu Jan 19 15:25:37 PST 2012

Why don't you try completely removing and purging nvidia from your system, and then reinstalling -nvidia through jockey again. Doublecheck that your /var/log/Xorg.0.log shows "NVIDIA dlloader X Driver 295" or similar.
