I had a chance to try the 11.10 driver and so far it looks like all problems were completely fixed for me.
Wellsprings NPCs no longer flicker and no more floating/flickering weapons/bullets.

EDIT: history working with previous drivers is as follows - 11.9 driver: game did not launch (CTD on startup)
11.9 driver + Oct 3 hotfix: game launched fine, excellent frame rate, excellent appearance except for occasional and very brief artifacting in locations like Ghost hideout. The artifacting appeared as striated thin diagonal lines and did not affect gameplay very much as it was a rare occurance.
11.9 driver + Oct 4 Rage performance driver: no more striated line artifacts, however, in some areas I experienced phantom weapon parts or bullets floating in the air next to my gun. Also NPC flickering in Wellspring.
11.10 driver: fixed NPC flickering/floating bullets etc., and so far no other problems
EDIT: very slight twitching noticed with one of the NPCs in WellspringAfter installing the 11.10 driver, I loaded up a save from Wellspring and all the NPC flickering seemed to be fixed. Also traveled around to areas where there were previously weapon glitches/flickering/ floating bullets. All of the problems appeared to be fixed.
However, when I spoke with the merchant in Wellspring for the first time, there is a very slight flickering noticeable only when you are in the "buy" menu:
His head twitches a very tiny bit from side to side: http://cloud.steampowered.com/ugc/558669913737969576/112A270A64F5D8A82482AE9D07E21BCCD37BF47A/
This is nothing like the flickering experienced before the 11.10 driver.
So far I haven't noticed anything similar to this with any other NPCs in Wellspring. I have not made it to the Mutant Bash TV area yet.
