Caves still causing delay (dst)

I'm not sure if this is the place to post for dst stuff, but i have had this problem for a while where every world with caves adds a 1 second delay to everything i do. Harvesting grass, each chop on a tree, picking stuff up from the ground, mining boulders, and especially in combat. My pc is far above the required specs for dst, and i have even tried this on a dedicated server but the delay persists.

I messed around in the files a long time ago and somehow got rid of the delay on worlds with caves, but i have no idea what i did to get rid of it. Does anyone know a solid fix for action delay with caves? Or maybe a mod that gets rid of the delay. Just to make it clear, its delay, not lag. Game still runs fine, but my character pauses for a second for everything i do.
