Please update if them problem is resolved, I am also having a very similar issue! Lag started when I crafted a Crafting Station from Tinkers Construct. Deleted the Crafting Station from the world, and restarted minecraft. The intense lag and FPS loss was gone, but ever since I have experienced lag when opening inventories etc.

I also went to the Nether for the first time, and the block-lag (or tick lag, not sure which) was rather extreme. Hit F3 and saw almost constant 200+ chunk updates, and according to Journey Map (browser not up) it was generating chunks far outside my render distance.

TL;DR and guess of what the issue is: At some point (most likely due to a combination of mods) Minecraft starts trying to render and keep rendered (chunk-loaded) chunks that are outside of your specified render range. Minecraft is up right now and I see every 15 seconds a report in the console of server overload.

I noticed my game keeping like 30+ chunks loaded about 2k blocks away in an area of the map i've never been to. This is on a single player world so can't be another person causing it and when i visited the area to investigate i didn't see anything there that would cause it. The chunks were loaded normally like i was there according to opis and not being forceloaded.

How does one discover if chunks are being kept loaded using Opis? I'm curious if this is happening in my world.

Open the big map and at the top right there is a filter thing which i believe by default is set to "none" (can't remember exactly since i haven't played today and the game takes far too long to load up just to check something), you just highlight it with your mouse and use the scroll wheel and it will change the filter, keep scrolling until you get to the one for loaded chunks, you will know if it is the right one when you see a bunch of green squares on the map around where you are. To clarify though, Opis is disabled by default on the launcher so if you didn't swap out Journeymap for it you won't get this ability, at least if Journeymap has this ability i don't know how to do it.

Sorry for late reply, my internet was out like all day today (stupid Comcast).

Thank you! I'd already switched to Opis, since JourneyMap was just a bit laggier than I'd have liked, I just never knew how to change that filter... ^^; Doesn't look like I'm experiencing that problem (yet?). Just the chunks around me, and the expected spawn chunks.

No problem, the map has some pretty handy features. Unfortunately the lack of beacons and some of the other features journeymap has kinda stops me from fully using it despite having better performance with it.

my issue is not completly fixed however it did help. I did notice the biggest problem was the number of entities being loaded. seems like they were not dropping off either. after drilling down in the debug menu the biggest problem was under "unspecified" so I have a feeling on of the mods that adds that is buggy. correct it me I am wrong but do thaumcraft nodes still talk to each other? maybe something else I don't have to explore too often and it seems to happen mostly then.
