Might help if you posted your system specs, 1Cane. IIRC you are using a 3-monitor setup. Have you tried using just one monitor and resetting your game resolution to that monitor's resolution? 3 monitors requires pushing an awful lot of pixels.
My biggest frame rate hit is shadows, when I disable them I get 10+ more fps. Also I moved the graphics sliders back toward the middle, reducing terrain detail, trees, etc. Would be interested to see what your frame rate is like with minimum graphics settings and just one monitor.
I noticed nVidia just came out with new drivers. If you have an nVidia card, might help to update your drivers.
