After some tweaking game video preferences for increased performance and downloading an upgrade for my video driver (which improves other games too) I find I am getting perfectly acceptable framerates (average 25 to 45 or so) in the air - though slow on the ground (12 - 20 on a CV deck).
My old system:
Win98
celeron 1000 mhz
GeForce2 MX/400 (upgraded to 56.42 drivers)
256 mb ram
30 gig HD
I now prefer AH2 - better gunnery model and myriad other little improvements. Some graphical and other bugs being ironed out as we speak.
If my system can handle it well I expect most currently flying AH1 could, with some tweaking.
BONUS: currently fly most (all?) perk planes for free in beta! It's your chance to squander as many rare high performance aircraft as you wish while learning how to handle them in 'real' combat at no cost.
