oh, and I can provide a github link to the code I use for my mod if needed to resolve this issue
I experience the same. Though it didn’t do that with earlier versions, now there are lag spikes, especially when looking towards a side (north south east west), but less so when looking up or down. It does that not matter how many blocks are actually rendered. And beside issue MCPE-236390, there is nothing in the logs that could explain that.
@Test Pattern I’m afraid it doesn’t, but thanks for the input anyway. That may a clue of where the issue actually is.
