the LAG

You mention getting horrible problems in Nivla and Llevigar. Are you using fast graphics to make rendering leaves less intensive? Low FPS sounds like a computer issue, not a server one. I'd recommend installing a handful of performance mods (use Modrinth; its's easier to work with than Prism imo). I know that Modrinth has a pre-made ultra-performance modpack you can try; that could increase your fps pretty meaningfully. I think it's called "simply optimized".

 

Sodium, Ferrite-core, Scalable-lux, Lithium, Entity Culling, and a leaf Culling mod I can't quite remember the name of have helped me a lot. I think 1.21.11 should be faster as well.

 

I had a ?/35 horse that got turned into 2/90/120 all around

 

I guess I'll try that. Still a bit irked that I have to play Wynncraft with mods; I've made a minor point since Prism stopped working of playing Wynncraft vanilla specifically to test it on the count of "can be played completely adequately without any mods", which it was formerly meeting and ceased to meet the moment the Fruma update dropped.

I was specifically recommended to use 1.21.4, although I don't remember why.

 

On Friday, Wynncraft was also nearly unplayable with lag for myself, but today the only points during which I experienced even minor lag was when I was in the midst of a ten-person bat cave party. Have you logged on at all today? I'm curious to see if your performance has bettered as well.

 

My performance today is okay. It's not great. But it's not terrible.

 

What GPU are you using? I wouldn't think that performance mods are necessary unless it's something either integrated or very old.
