That's likely, and it fits with that I see from memory use and checking the process mapping in detail. I thought I saved pmap and my own memory program's output for the
older driver, but now I can't find it to compare, and changing drivers is currently highly inconvienient.
I was hoping someone from nVidia could give a definitive answer.
If someone with one of the older drivers wants to post the output of pmap, that would be cool.
