Re: 32 bit version has far better performance than 64 bit on Win 7 64 bit (Thoroughly tested)

I tried a bunch of stuff based on this and other posts:

- 32bit mode

- low priority for the app

- limited fps to 60 with gametime command (this actually made it much worse)

- windowed & borderless modes

- no VOIP

For me, the only fix was to disable SLI.  I have 2 680s, and without SLI it plays super-smooth most of the time, even with settings on Ultra (minus MSAA since I use FXAA).  With SLI, the in-game FPS monitor would show good FPS, but it just wasn't panning smoothly.  As soon as I disabled SLI, the same section of the game was much more enjoyable.  I'm using Win7 64bit (SP1) with Punkbuster manually updated.

Here's hoping they'll fix SLI.  My 2 570s ran BF3 silky smooth.
