I saw that you did a good job on reducing the polygons count and the drawcalls by simplifying the model and making some texture unnecessary (on my 7700K I have ~2-5FPS more on complex airport when on exterior view) , but In my opinion the removal of the doors and the cargo door animation hurting the experience of the flight because I do like to see the 767 work together with GSX or jetways when using the aircraft in normal procedure. as a scenery developer I know that optimizing the number of texture and polygons number improving the preference but do animations hurts the preference?

this is only my opinion and I will be happy to see animation (at least for the doors) on the next update

thank you
