I have a scene with a few hundred of trees. When debugging rendering performance, I have found out that `afterCullingOutputReady.Invoke` takes majority of the frame time. And the more trees are on the screen the longer it takes. I have also found out that this time is only caused by trees in the view frustum as trees outside of view do not increase this time. All trees are clones of 3 prefabs generated by SpeedTree, with original materials, and with 3 LoDs where the last level is billboard (all generated by SpeedTree). Is there any way to cut down on this time? I had to reduce the number of trees in the scene to half to get FPS above 60. Here is an output from profiler: Thanks!
