Crippling lag in world

[sage199 2]

So I started a new TFC world a noticed that when ever a generated a few too many chunks my framerate would go from 50-80 to less than 1 frame a second. As I continued to play this would happened more often and now it's too the point to where after only playing the world for a few second the lag starts.

Make a backup of your world, then remove all mods except for TFC. Load up the world, and click Yes when the FML error pops up. Does the lag still happen? If not, then the lag is not caused by TFC, and you'll have to figure out what other mod is causing it, and contact their support. Note that loading the world with only TFC is going to delete all of the non-TFC blocks and items from your game, so you should not do this without first making a backup!

To keep from making a new thread I'll post my lag issue here. If I'm exploring, even in areas I've been in before, I always start getting continuous lag spikes with about 4 seconds in between them. I end up just restarting the game and it's fine. If I travel by boat, I can usually get game crashing lag. Is this normal?

 

Only other mod I have is fastcraft. Also turned down my render distance to 8 chunks.

What version of java are you using? Is your OS 64bit or 32bit? Are you using the matching bit version of java? Are you using any JVM arguments to help with garbage collection?

The best hardware specs in the world don't matter if the software isn't properly configured to use it.

Well I remember a few weeks ago updating java and of course I installed 32 bit instead of 64 bit. I suspect things will run much better now. Good catch Kitty.

I do think that using 32 bit is the bad idea...

Correct. Mark88fan was saying that he installed 32bit by mistake, and forgot about it. So he's updating to 64bit and expects it will run better.

Just tested it with only terrafirmacraft installed. Still get lag that is just as bad.

Alright, click Edit Profile on the launcher, and at the very bottom check the JVM Arguments box and put the following in the field:

-Xmn1G -Xms1G -Xmx2G -XX:NewSize=512M -XX:SurvivorRatio=2 -XX:+DisableExplicitGC -XX:ParallelGCThreads=4 -d64 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalPacing -XX:+AggressiveOpts

If your processor can handle more than 4 threads (like a quad-core with hyperthreading), change ParallelGCThreads to the number of threads your processor can handle.
