Hi there!
I can't see why my plugin reduces your fps so much with only your description, because I believe it's addition on the update functions are not that relevant to this point. But also I never tested it with 92 platforms ^^''
I could find a way to do what you asked, only update the platforms according to a distance. But it will be nice if you could send me that project replicating the issue so I can really see what is causing the lag. Can you send me on discord?
