Subject: [PATCH] Implement Chunk Priority / Urgency System for Chunks
|
|
|
|
Mark chunks that are blocking main thread for world generation as urgent
|
|
|
|
Implements a general priority system so that chunks that are sorted in
|
|
the generator queues can prioritize certain chunks over another.
|
|
|
|
Urgent chunks will jump to the front of the line, ensuring that a
|
|
sync chunk load on an ungenerated chunk does not lag the server for
|
|
a long period of time if the servers generator queues are filled with
|
|
lots of chunks already.
|
|
|
|
This massively reduces the lag spikes from sync chunk gens.
|
|
|
|
Then we further prioritize loading order so nearby chunks have higher
|
|
priority than distant chunks, reducing the pressure a high no tick
|
|
view distance holds on you.
|
|
|
|
Chunks in front of the player have higher priority, to help with
|
|
fast traveling players keep up with their movement.
