I'm not sure if this is the right place for this, or if it should be considered a graphics issue, but here it it...
I recently installed the Alabeo's Diamond DA42 'Twin Star' for FSX. All went well (I thought) until I loaded the aircraft for a flight. The interior views looked as well as expected but when I went to an external view, much of the plane was missing. I have had this happen with another aircraft as well but can't remember which one. Backing out of flight mode and changing to a different livery did not correct the problem and when I went to internal views, most of the panel was now missing as well.
If this is some odd glitch or a setting I should change any help would be appreciated.
Of note may be the fact that this was an installation of V2.0 after removing V1.0 which had never had any problems.
It is too graphic intensive for your video card.
Lower some of the slides, autogen, clouds, shadows and AI.
The full aircraft should show up then.
Let us know how you do.
