The project easily gets 60-100 fps in Unity, but due to extreme lag (in some cases 0fps) almost unplayable in webGL and only semi-playable in the Windows version (like 4fps). I tried to open up Unity Profiler, and it said EditorLoop is in the range of 45~60%, and PlayerLoop is in the range of 30~50%. Don't know what it means. Don't know what to do.
