Aristois: v401
Minecraft: 1.18

Config:

The HitPlayer's mode for MultiAura targets all entities regardless if they were manually hit once.

Aristois version: v401
Minecraft version: 1.18

Video:

Depending on the environment around the player the FPS can drop significantly.
In this example it's dropping from around 30 fps to 5.

Build: v399 Donor Edition (on 1.18-pre4)

Example:

@netiahkj Did you install Opitfine through the Addon Marketplace in Aristois? I think that may be the problem since Optifine doesn't work for me when I've installed it.

I found this thread: https://discuss.aristois.net/topic/13/how-to-uninstall-optifine-optifine-error-on-startup
It shows you how to uninstall Optifine.

This seems to be a problem with Optifine. Remove Optifine and see if it works.

Reproduction: Turn on CaveFinder Depth Mode. Try looking at cave through grass block, as opposed to dirt block. Notice how you can't see the cave through grass blocks, but can through dirt blocks (or another type of block)

Image: Looking attempting to look at cave through grass blocks. The cave doesn't render.

Image: Looking at same cave through dirt blocks. The cave renders.

Edit: You can only see transparent blocks through grass blocks. So rails, glow berries, etc. render fine. Just not solid blocks.
