This is a quick shot of the Gotha that we had in KOE. It's about the same level of detail as the GT Gotha.
One aircraft flew fine. Put 6 aircraft in the world and the frame rate tanked, according to one of the programmers. The main problem was that our renderer had not been optimized. Seems the other programmer who was suppose to be working on it was pre-occupied with trying to fix the terrain system and hadn't spent anytime on the renderer.
Both programmers told me that the number of polygons in a model was no longer the main issue with the new video cards. The enemy of high frame rates was groups. The damage model required that the plane be able to break apart into logical groups. With all the struts and the large wings our bomber models had a very high number of groups.
