Game freezing dropping frames every few seconds

[CalebS92 1]

I don't know if this is an issues with Minecraft, terra firma, or just my set up but I'm trying to play and i notice that the amount of ram being used goes up from 26% to about 60% (of 2 GB) when it hits 60 the frames drop to zero and resets at 26 and climbs again, it takes about 30 seconds for this to happen.

 

Also when i try to cut down trees they don't fall, i can still get thatch and stones but 5 out of 6 times the tree wont fall.

 

Help! Please? I really want to enjoy this mod but its really frustrating.

 

Thanks

What are the specs of your computer? It looks like it is struggling with keeping up with Minecraft's garbage collection. There are a few JVM arguments you can add to the profile on the launcher to fix this, but they are different for every system depending on its specs. The primary info needed is:

 

• Operating System
  • 32Bit or 64Bit?
• RAM
• Processor
  • # Cores
  • # Threads it can run at once

Windows 8.1 64 bit

8 GB Ram

Intel Core i7 2.4GHz 

 

Thanks for any help

I'll need a bit more specific information about the processor. There are multiple i7's with multiple numbers of cores and some of them even support hyperthreading so they can run even more threads at once.

4th generation Intel® Core™ i7-4700MQ (2.40GHz 1600MHz 6MB)

I just copied it from where I bought it, its a lenovo y410p, sorry if this isn't enough, thanks for the help

Perfect.

 

On your launcher hit "Edit Profile" then at the very bottom check the box that is next to "JVM Arguments:" then clear out anything you have in the text field and instead put this:

-Xmn1G -Xms2G -Xmx2G -XX:NewSize=512M -XX:SurvivorRatio=2 -XX:+DisableExplicitGC -XX:ParallelGCThreads=8 -d64 -XX:+UseConcMarkSweepGC -XX:+CMSIncrementalPacing -XX:+AggressiveOpts 

If that seems to cause more problems than it solves, try changing the ParallelGCThreads to 4

error: this java instance does not support a 64-bit JVM please install the desired version.

[Kittychanley 1,002]

Well that explains your original issue as well. You only have 32 bit java installed, which means that you were greatly limited in the processing of that anyways.

 

I'm assuming you can figure out how to uninstall your old 32 bit java versions, and go install 64 bit?

Yeah, thanks, i though i had 64 bit. Thanks a lot. I appreciate it
