106 fps
1920x1080, E8400 at 3GHz, 8GB RAM, HD7870 2GB GPU, Windows XP 32 bit (which only sees 4GB of the RAM, the rest is for dual boot to Linux), graphics card driver AA set for adaptive MSAA.
(My normal, with almost everything cranked up except EM=none and Post Lighting disabled, is 40 fps. This is online, as offline the tank drones I have set up are visible from the tower and reduce fps. As with bustr the worst frame rates I get are in the hanger, i.e. below 20.)
