i tested using the quick mission, bomber raid over london, before patch everything on high, during fights it was about 20-23 fps, but including ground shots, down to 13-15 fps,,
after the patch i probably gained abuot 5 fps in the air, but including ground shots, about 3-4 fps.
then,
i reduced all my settings to medium that pertain to any ground stuff, but aircraft/damage etc i left high
antiliasing is set to off,
now im getting between 30-55 fps over water and about 28-40 over land!(still stutters a bit)
i am quite happy with the game play
but i appreciate others are struggling!
personally i will be upgrading my card from ati 6870 to poss a GTX 480 / if and when they patch/fix SLI/CF then i will get another one!
on another note, hat off to the DEVS! i see there were/are some impatient people on here,, but at least you guys are doing the best to give us a great game, i would rather have it as it is than not at all
