Yes, PPF was on for the screen-shots. I usually turn it off for actual combat missions though. The idea here was to get into the 3D world at my monitor's native 1680x1050 resolution and snag some pics proving that version 1.2 does indeed use higher resolutions now.
Re: AA/AF, etc. I have them at very low levels (2x each IIRC) through my video drivers. I could crank those up, and I probably will at some point in the future when "shutter-bug-itis" gets me. But for actual game-play, I accept a certain amount of "jaggies" for increased frame rates.
FWIW, general system specs:
- Intel C2D E6400
2GB RAM (1066Mhz)
GeForce 7900 GS w/256mb
250gb SATA HDD
Win XP Pro SP2
Plus the usual laundry list of other stuff...
