For real this time I think this is the one.
We’ve gone from about 23 percent usage down to a maximum of only 2 percent, and when idle or not moving it sits around 0.78 percent. There’s still a brief TPS dip when loading new areas, but that’s about it.
Remaining issues:
- Ocean ice isn’t melting correctly
- Snow sometimes spawns inside structures
I’ll test both once I run PA in my world.
Otherwise, it’s looking really solid. Random snowfall is back, snow layers behave properly, and melting is a bit slower but the system is much more efficient now.
And yes, I finally tested on a dedicated server. Turns out the “runServer” in IntelliJ isn’t the same thing, since it can handle client classes and skip certain checks that would crash a true dedicated setup.
