which console?
the PS3 had issues much like the 360, though the fram rate issue seemed to be worse on the PS3 for some reason (could be wrong?)
The PS3 has since been patched and its resolved alot of the issues, though mixed reports are coming in about the frame rates. On the whole though they are not that bad and i wouldnt say they ruin the game in any way what so ever.
The 360 version is yet to be patched but should be happening extremely soon
if you like flying games that are set during WW2 and ffer a little tast of realism (not stupidity like blazing angels etc) then this is a game i would highly recommend.
