about fps, i got constantly around 60fps with gtx660. everytime i start the game, i have to change the config, since it doesnt save the config. i just have to change the graphic quality 2 or 3 times to the left at the slider and choose the middle one at the vsync option (the first one turns on the v-sync, 2nd disable at tries to cap at 60fps and 3rd disable and cap at 30fps). no need to touch the right side of the config window, since the slider will disable them anyway.
