I also replaced the nvidia drivers from 331.65 to 337.88 - this revision
gave me a lot more performance but I can remember I had this issue on
native Windows too.

So after a lot of testing, pain, time consuming days (and nights) its
really working great - not perfect maybe.

Modifying it won't get you more speed.

I was originally planning to use a GTX690 and pass one GPU to each of my VMs, but I eventually replaced it with a pair of 780Tis.

I am running on a SSD backed zvol, with gplpv.
