With the release of these two updates, I highly recommend a world reset. There have been substantial changes to some of world generation for both packs as well as changes to BoP if you use that generation on its own, or with ATG. Continuing a world with either update is at your own risk. That aside, I have been profiling the packs to find ways around the lag. As always, the link to my JVM arguments can be found in my signature. The start of the new year also starts some major revisions to these profiling against Monster. Do note, not everyone will get the same results from them, and some people may not receive any benefit (based on your computer specs.) Horizons 1.0.8 and Monster 1.0.2 will NOT be moved to recommended. The versions being put on the launcher now, will be pushed to recommended on Thursday barring nothing unfortunate. If nothing else major shows its face, both packs should be pushed to stable (versions 1.1.x) within the next week or two. Change Logs can be viewed here as always.
