this are a few things I've noticed:
The Known text boxes
Fw-190 gunsight not visible
field gun has no sound
the muzzle flash render problem at 1024/768 (it disappears at higher resolution -1280/1024)
Tower on the CV crashes to desktop
changing resolution to 1600/1200 gives "unknown error"
frame rates are ok for a beta (30-80)
