I Installed various mods without following any mod pack, they just work together.
But when I installed your mod, my game when from this

to this

If you want more info about my mods then:
Better End, Better Nether, William Wyther Overhauled Overworld mod and its addon except for Primordial Shore
and some Structure-Add-Mods . The rest are more recipe mod, client mod I don't think these will cause conflict.

hmm, this mod is a data pack of dimensions, there is no content that gets ticked. Were you even in one of the dimensions when you took the measurement?

No I took measure in Overworld, I have never got in a Dimession. Also this TPS drop sometime doesn't happen immediately It may happended right after I create the world or after 5-10 minutes of playing. And after I removed your mod I can't re-enter my old world.

The lag is odd, since the mod is essentially a data pack mod, so if you aren't in the dimension, the mod is doing nothing.

The removal problem showed up recently, still trying to figure out what is causing that.

I check the log and It said:

repeatly when the TPS dropped.

I do not believe this is a result of the mining dims mods since it is simple datapacck mod. I could not replicate this either.
