Laggy map, profiler file available.. please help me understand

I agree it doesn’t make sense and there is a problem, but it is most likely still possible to work around the issue by over-optimizing your scene to make room. I hate to suggest something like that but I didn’t want to give you the false hope that somebody will solve this by your deadline. I know the over optimizing thing may not be fun it it could be a last ditch option.
