serious lag from Mirror's edge

So im playing Mirrors edge and i keep getting lag in the big escape levels IE Ropeburn. im normally getting 40-60 fps but right when the actually escape part starts i drop to 15 then to around 4. im running dual GTX 660 SLI 8Gbs ddr3 1333 RAM and a 3.7ghz i7 LGA 2011 processor. i havent even touched the overclocking options in the EVEGA Precision X program just adjusting the fan to full power, and both cards dont exceed 40 degrees celsius. i just updated the graphics drivers and its still happening i just dont understand how a 2009 game can cause so much lag when i can run battlefield 3 at 40 FPS on ultra settings like its cool. any thoughts ladies and gents?

Do you have "PhysX" enabled, and if so, is it running on the GPU or CPU? Inconsistancy
