im playing on an onboard intel 945 video chip (for now), and i get random black dots everywhere on screen with everything on low settings. i still get 30-35 fps average though, very playable. processor is an intel core2duo e7300 2.67GHz, 2GB DDR2 667, 1TB maxtor 7200rpm 32mb cache hdd, in a shuttle K45 barebone system.
good news is i'm on newegg right now to buy components for a new pc build specifically for this AHII terrain update. =)
would there be foam effects on those waves? getting a water trail spray when flying low on the deck 30-40 ft above water would really be impressive coding!
