Hi,

I apologize if this issue is somehow submitted incorrectly, I've never used github before.

I'm working on a modpack for my friends and found that I was dropping from 120fps to 4fps when going near some structures. I found out that it wasn't the structures themselves causing this lag, but the amount of magma slimes and blazes that were spawning inside of it. I checked on vanilla and this lag did not exist, and spent a few hours narrowing down the modlist until I found the culprit, and it was unfortunately this mod. This mod was on (as far as I'm aware) default settings, and the mod that generated the structures/spawners where I noticed heavy amounts of lag was When Dungeons Arise.

I'm submitting this before I forget, but I'm going to try now to refine the settings and see if I can clear up the lag and still keep the mod working.

Thank you!

I'd like to append to this that disabling dynamic entity lighting in the settings solved these massive fps issues for me!

There's not much of a way around this unfortunately but I think dynamic entity lighting should maybe be off by default for this reason. I might push an update to do that.

There is basically zero impact with just the player holding a torch, but lighting updates for hundreds of entities can be expensive

Disabling it by default would have saved modding noob me a lot of frustration, might be worth trying! I've noticed a lot of people seemed to be having similar issues with the same WDA structures so I wouldn't be surprised if they were experiencing the same issue on their own installs. I should probably leave a comment on WDA's page to let the mod author know.

Should be fixed in latest release.
