Subject: [PATCH] Mid Tick Chunk Tasks - Speed up processing of chunk loads and
|
|
generation
|
|
|
|
Credit to Spotted for the idea
|
|
|
|
A lot of the new chunk system requires constant back and forth the main thread
|
|
to handle priority scheduling and ensuring conflicting tasks do not run at the
|
|
same time.
|
|
|
|
The issue is, these queues are only checked at either:
|
|
|
|
A) Sync Chunk Loads
|
|
B) End of Tick while sleeping
|
|
|
|
This results in generating chunks sitting waiting for a full tick to
|
|
complete before it will even start the next unit of work to do.
|
|
|
|
Additionally, this also delays loading of chunks until this same timing.
|
|
|
|
We will now periodically poll the chunk task queues throughout the tick,
|
|
looking for work to do.
|
|
We do this in a fair method that considers all worlds, not just the one being
|
|
ticked, so that each world can get 1 task procesed each before the next pass.
|
|
|
|
In a view distance of 15, chunk loading performance was visually faster on the client.
|
|
|
|
Flying at high speed in spectator mode was able to keep up with chunk loading (as long as they are already generated)
