[0.15.19] Drop FPS iusse

[McGuten]

Hello

We have a problem when we play online, first, when someone join the server, it takes a lot to catch up and once you enter you have low FPS problems that I as a server do not have, my FPSs are stable at 60 but when someone logs in, the FPS will vary between 5 and 60 depending on the moment.

I let you the game save to test it
