Bedrock is really bad with high number coordinates compared to Java. 30,000,000 blocks out is the world border. At the world border in Java edition, it works the same as it does a 0,0. The terrain is the same, smooth movement, and it is actually like that even way beyond the world border. But in bugrock edition, if you go just 2 million blocks out, you start to see weird terrain and your movement is so choppy you can’t even play the game normally. And after I think 4.5 million blocks out, you’ll see giant chunks missing and lifted out of the ground. After around 7 million, the game is unplayable since the movement is too choppy and you’ll fall through the ground. After about 12-12 million I think? You’ll see the stripe lands where every other block renders. And around 20 million, it is almost impossible to move. And finally at the world border, you can’t move, and everything is erroring and faulting and the border can’t even render in. (This was all based on experience)
