Question about Mystcraft

[Riotkidd]

I'm trying out mystcraft right now to get some crystal but I heard that it cause lag so I'm wondering does the chunk in age stay loaded if there is no chunk loader around after you leave and if the book to that age get destroy does the age still stay until the owner decide to refresh the age.

The Age's existence doesn't depend on the book's existence. I'm not sure if it stays loaded. If it does, it would be like the overworld keeping the area around the origin (coordinates 0,0) loaded.

No, mystcraft ages do not stay loaded unless there is a player or chunkloader present.

If you have a chunkloader, when you restart the world/server you need to enter the mystcraft age at least once for the chunkloader to take effect and actually load the chunks again.

How exactly does crystal cause lag?

 

[beringtom]

Mystcraft had a memory leak problem, and that was causing the lag issue. I'm unsure if the problem was identified and fixed.

 

[MFINN23]

Ah the memory leak when changing dimensions? That was pretty annoying lol. That particular one didn't seem to be dependent on crystals though. Is there another involving crystals?

 

[beringtom]

no? think he means lag from the mod not the crystals

 

[Riotkidd]

Yeah sorry if you misunderstood and think I said crystal cause the lag. I meant that I wanted to get crystal but I'm worry about lag related issue from mystcraft so I didn't get any yet.

The memory leak is still there on the Mystcraft version in the feed the beast 1.4.2 pack. All you have to do is exit your client after so many travels and you wont have a problem.
However there is no lag by just having the ages/portals. I have 15 ages always loaded with world anchors on my server and its always lag free.
