So this is just a theory of mine, but this 'Outside Exterior Model - Low FPS' issue might have to do with the fact that the exterior model file of the 767 CAPTAIN II (.mdl file size= 275 MB) is about 6 times larger in disk size compared to other payware add-on aircraft such as the 737NGXu (38 MB) and the QW787 (37 MB). In the past I've done some modeling myself, I do know for sure: Generally speaking (and of course there are other factors as well) the larger the size of the model file, the more complicated the model is... In other words, it will have a bigger impact on performance!

I'd like to add the following: And yes, it does run heavier on the frames compared to other payware add-on aircraft.
