Minecraft Forums

Usually Minecraft plays well enough at 30-40FPS, though sometimes, out of the random, Minecraft will freeze for a good 7-20 seconds, and anything done between that time will have already happened. For example, if it did this while I was fighting, say, a Wither, it would freeze, and when everything returns to normal, Wither would have killed me and be terrorizing some other animals. After that it won't happen for another 40 minutes or so.

I can be doing anything when this happens; crafting, mining a block, sleeping, falling, or even simply standing still.

This is nothing that's too big of a problem, only a minor annoyance since if I lose the focus out of Minecraft as soon as things lock up, it'll pause to that moment, and said Wither would have not had the advantage. I'm just curious; what does this, and how do I fix it?

Specs are:

• AMD Athlon II X2 processor
3.0GHz


• 4GB DDR3 SDRAM system memory
• Integrated ATI Radeon HD 4200 Graphics
• Window 7 Home Premium

JVM arguments are:

-XX:MaxPermSize=256m -Xms1g -Xmx2596m

If I don't have the MaxPermSize in, Minecraft won't even load with mods.

Modpack is DW20 1.7.10 with Fastcraft taken out and Optifine added in.

No texture packs are being used.

Bump.

You're killing me gais.

Anyone else? :I

Have you fixed your start up script?

Doesn't help when I don't know what exactly to fix. That's kinda like half an answer.

Your start up script only showed the your ram configuration it did not configure your server to your machine that it is running on you need to set the arguments to match the hardware you are using same as you do in minecraft client

Again, kinda like half an answer bro. Telling me the general idea of what to add but not the statements specifically is redundant. I'm no Java wizard at all.

Beside my last PC didn't need any arguments at all. It was just launch and play.

This is what I use and works fine for me but you would need to tweak for your system. These were for a Java 1.8 64bit setup.

java -Xms2048M -Xmx2048M -native -server -d64 -XX:ParallelGCThreads=4 -XX:+UseConcMarkSweepGC -XX:+UseParNewGC -XX:+CMSIncrementalPacing -XX:+AggressiveOpts -XX:+CMSParallelRemarkEnabled -XX:+DisableExplicitGC -XX:MaxGCPauseMillis=500 -XX:SurvivorRatio=16 -XX:TargetSurvivorRatio=90 -XX:+UseAdaptiveGCBoundary -XX:-UseGCOverheadLimit -XX:UseSSE=3 -XX:MetaspaceSize=128m -XX:LargePageSizeInBytes=4m

I suggest you look through these and figure out what each does and if it is needed in your instance. Here is documentation to assist you.

THANK YOU.Something helpful.

I'll be sure to copy these over and experiment and let you know if the problem is fixed.
