So my world mostly started lagging once I got to around 29-30 mb of that world but I don’t think it has to do anything with the file size of the world. All I know is when I’m signed in to my Microsoft/Xbox account, I get Huge lag spikes with only 1-3 seconds of smooth/high fps in between each spike. However if I sign out and play offline, there’s absolutely no problem, it plays smooth, no lag. Seems to be some sort of connection issue in the game I’m not sure.

Ok scratch that, it’s worse. Online or offline when I play on my ONLY survival world (it’s about 27 mb), the lag is so bad I can’t even play it. I tried to bear through it as long as possible but the whole game just crashes out. Sometimes even the main menu screen will be laggy for a bit, and even going between world selection, marketplace, main menu and all that, can cause lag. Also the Minecraft title will sometimes not be there. [EDIT:] I found a fix to the lag, I had to delete the game and re-download it.
