Adding to Thunderchaser’s comment, the PC essentialy needs to display the blocks within these chunks. Problem being, that with each level of render distance higher the amount of chunks needed to be rendered go up exponentialy. meaning, while going up and starting at a render distance of 1, 1 -> 9 -> 25 -> 49 -> 81 -> 121 -> etc. As you can see the increments between those numbers become higher and higher because essentialy, every new layer on the rendered square has more chunks that the layer before.
