I don't see any settings related to the emissions produced by Froglights, anytime I go near a group of them my frames drop from 70-90 on a 4070 to less than 30. This is a massive problem in my opinion. Are there any options to solve this? Thanks!

Without froglights in render distance

I highly doubt it's the froglights causing that, most likely there's something else in that direction causing it. Can't replicate in a flat-world either.

Fair, I can't replicate this with a single block either. I can't find what's causing it, unless its the large collection of chests and signs. (chests have floating block displays, maybe that?) Thanks for your efforts too.

Signs, item frames, anything that is a block entity. You can try installing a smarter culling mod. I think there is one called "MoreCulling" and "Entity Culling" on fabric and forge. They have a different approach each and so different things, so you can install them alongside.
