I have a level with 10 rooms. When the camera is facing the direction of the other rooms, the GC goes crazy. I don't have anything that is being destroyed. I don't have any particles or effects. This is causing the performance to go from 250fps to 100fps (on mobile it is 60fps to 15fps). Is there something I can do about this? This is what the camera sees. It just a brick wall. Behind the wall is the other rooms: As you can see when I adjust the "Far Clipping Plane" of the camera, there is a significant performance difference.
