A similar issue for me, but sounds worse than already reported, I am running 64 bit and consistently get 2-3FPS from the off on any MP mission. My clan recently switched to 64 bit and everyone else (that's 40-50pax on a gaming night) is seeing improved FPS - WTF is going on?
I had the same issue last week running my old GTX780 - dropping the sharp end of £500 on a new card only to find the FPS still knackered is pretty frustrating!
