i7 processor, 16GB ram. Initially 4GB ram allocated to Sky factory 3. Tried increasing to 8GB, no change.

I downloaded and installed Sky Factory 3 from the FTB launcher, and played for several weeks with no issues. I had about 20 cloches producing things, about 20 crucibles making lava and powering a couple dozen or so auto hammers and sieves, a big reactor making around 70K per tick, etc.

Then one night, it just started stuttering and lagging. I experienced this same behavior on an older laptop about 2 years ago, and it made me give up the game. At the time, I assumed my laptop was underpowered. When I eventually bought a new laptop, I tried sky factory again, with the same results. Several weeks/months playing, and then one day it just became super laggy.

I've destroyed all my load chunk devices, removed all my lava/crucible stuff, increased my ram, and its still laggy.

I've watched the Achievement Hunters and other groups take down the Chaos Dragon and it seem very smooth. I can barely kill a pig without a large delay.

Any ideas?

After researching the issue for a while, I discovered that too many machines in one chunk was the issue.

Using F3+G to see the chunks, I broke up all my machinery into small chunks, no more than 16 machines per chunk. That seems to have fixed the problem.
