Very smooth gameplay so far with an AMD 64 3200+, 2 gig RAM, nvidia 6600GT 128 mb on 77.77 drivers, 1280x1024 resolution, Audigy 2 ZS, Saitek X52 Hotas. 2xAA and 2xAF and no stutter. Might up the AA to 4x to see if it still plays well. I thought I was going to have trouble playing SB with this system and expected everything to look pretty ugly with the settings turned down, but I have been pleasantly surprised at just how well this runs on a mid range system. Congrats to the devs on some excellent optimized coding :thumbup:
