As title.
I'm running the game maxed out with SMAA1x at 1920x1200
on a GTX580 SLI, i7 2600@4.2GHz, 8GB RAM.

The games average 50FPS with a lowest framerate of 40FPS.
This is quite boring, I like playing at 60FPS.

Can you suggest me what settings to lower to get better framerate without
impacting too much on the visual quality?

Thanks.

I average around 75fps with setting at very high, 1920x1080 @ 120hz, low motion blur, AA 16x, and texture resolution @ very high.
