Loading is faster, but in game performance are actualy worse?

--noasync did not fix latency spikes.

it was good at the start of 2.3.1, everything is amazingly smooth, but the hotfix turned everything back to 2.3.0, constant stuttering due to loading, and --waitforpreload doesn't work either.

2.3.1 is what made it super jittery for me. I like the idea of preloading while you play but this needs to be optimized. I'm waiting for a hotfix.
It was really good right before 2.3.1, the only times I had low performance(aside from things that normally have poor performance, like towns and certain bosses(Malachai)) were when the servers lagged.
