1.6.1 is giving me unplayable FPS. I was getting very high FPS before, now it's about 6-10. I play on a gaming laptop, I run BF3 in ultra, I don't expect to get 6 FPS in a game that has 30 pixels on the screen at any given time.

My nvidia settings do that automatically, I have no idea why that stupid update would change that. But it did work so thanks, I guess.
Make it use the right videocard.
