If a map is played, but some of the content is missing, including models, the lack of those models will cause the map to lag terribly.
This can be tested, by opening a map, looking at the FPS counter, then, deleting some models that are normally in the view you were at, restarting ac, opening that same map at the same place, and look at the FPS counter. You will notice the FPS counter flickering rapidly. In the example I tried:
Before with mapmodels: 140 FPS, quite stable.
After without mapmodels: 115-150 FPS, unstable.
.. tested at the same place/map. I have a fast computer, so this is hard to tell normally, but for players on older machines, the results are obvious.
