Enabling anti-aliasing on the graphics card causes the cockpit in Flight Unlimited 3 to become black (see files "AA off.jpg" vs. "AA on.jpg" at https://skydrive.live.com/?cid=b386bbc8a1ade599&id=B386BBC8A1ADE599%21210) and some of the instruments (e.g. the inside of the Trainer's attitude indicator) disappear.
Specifically regarding the affected instruments, these areas only flicker into appearance when they're changing. So e.g. when the Trainer is in flight, the attitude indicator will be showing, but only because it is constantly flickering because it is constantly changing.
All updated patches for the game are installed. Varying AA from 2X to 16X does not resolve the issue. Geforce drivers tested with the game are v266.58, v285.62, v314.22, v320.00 and v320.18 without success.
I have used Cockpit Designer to deal with the issue of 3D area and cockpit area "rectangles". It removes the problem, but introduces a new one by changing the 3D area such that it is looking upwards (i.e. at a higher angle than normal).
Also, using DDfix causes the game to run only in 800*600, even though ddfix.ini is edited to specify a resolution of 1024*768.
Also, let me know if you need to see additional pictures or videos.
