When I first bought BF3 months ago I could run it on Ultra settings with 4x AA @ 1920x1080 and average around 45fps. I recently decided to dust off BF3 and to my dismay the patch has dropped my framerate to a very unplayable 5fps. Tried lowest settings, didn't work. Tried updating video card drivers, nothing.
Sifted through thread after thread of similar problems, all being fixed by various tricks, none of them seemed to work for me though.

If anyone has had this problem and was able to fix it, please share your knowledge.

Have tried driver sweeper, and completely reinstalling BF3, still no luck.
