Hello Minecraft Comunity,
recently I am experiencing a heavy problem while playing Minecraft.
Everything starts up normal with a decent amout of FPS (Shown in first picture) but after a few minutes it starts getting unplayable because of the low FPS/FPS drops (shown in second picture).
I'm using a NVIDIA ghraphics card and 2 GB RAM.
Of course I'm not a PC/Coding guru, so I'm asking the community!
I have the two F3 screens with all the information I have and my Graphics menu.
I was using the 1.10 snapshots but this also accures in other versions (also with optifine) and all worlds.
I don't know if Minecraft or my Computer is causing this, but it really destroys my Minecraft Experience!

Thank you for your help and support!



PS: I excuse my bad English, I'm german I'm also new to Minecraft Forum

OOps here are the pictures (as I said, I'm new to this :P)

It might be too much allocated RAM, but what are your JVM arg's in the launcher?

You might have mixed up XMX and XMN or something.

Do you use Optifine in the release versions?

The JVM arguments are probably not the problem based upon the screenshots.

The slowdown could be a bug in the snapshot, have you tried running an official version of MC?

Or the problem might be in your Nvidia drivers.

First off, thanks for the replies!
Secondly, I have the problem in all versions of minecraft (snapshot,full version,optifine)
This is the JVM argument I use: -Xmx2G (I had 4G before because I have 8GB Ram and I thought I had allocated too much RAM but that's most likely not the case )

Maybe it's helpful to say that I use 2 .minecraft folders for different Accounts (The default .minecraft folder and another one Called Mapmaking, the one that I use). For that I used the "Game Directory" argument in the profile Properties.

I will still try out your ways, thanks!

Schlutt what do you mean with XMX and XMN? I'm really not that much of a coding pro...

Sooo, I removed my secondary .minecraft folder and reset my original (saved recource packs and worlds).
First it seemed fine, but it started dropping after a few minutues again...
I also tried allocating more memmory but nothing!
I was also playing in vanilla 1.9.4

Is -Xmx2G your only JVM argument?

Maybe it's worth trying the default arg's too.

These work for me (with Java8_25)

-server -Xrs -Xmx2G -XX:ThreadPriorityPolicy=42 -XX:+TieredCompilation -XX:TargetSurvivorRatio=90 -XX:SurvivorRatio=8 -XX:MaxTenuringThreshold=15 -XX:+UnlockExperimentalVMOptions -XX:+UseBiasedLocking -XX:UseSSE=3 -XX:+UseCodeCacheFlushing -XX:+UseThreadPriorities -XX:+UseFastAccessorMethods -XX:+AggressiveOpts -XX:+ReduceSignalUsage -XX:+UseInterpreter -XX:+UseFastEmptyMethods -XX:+UseSharedSpaces -XX:AllocatePrefetchStyle=1 -XX:+AlwaysCompileLoopMethods -XX:SharedReadOnlySize=30m -XX:+UseConcMarkSweepGC -XX:+RewriteFrequentPairs -XX:+OptimizeStringConcat -XX:+CMSCleanOnEnter -XX:+UseInlineCaches

Even though you probably don't need most of them!

Here, On my F3 screenshot I just noticed that it says Mem:2731MB but Allocated: only 679MB! Maybe that's the problem...But how do I solve it?
Anyways, thank you for your Help Schlutt and gerbil!

I did all of that but the problem is this errow Message:

Error occurred during initialization of VM
Initial heap size set to a larger value than the maximum heap size
Picked up _JAVA_OPTIONS: -Xmx3072m

when I try to allocate more than 3GB of Ram
THe weird thing is that I HAVE 64bit Java installed, so I'm really confused :/

_JAVA_OPTIONS is an environment variable that is set and caps what you can set Xms to, but you don't need more memory.

Your Xmx already allows more than is needed, this is why allocated is only 679M, MC hasn't needed more than that, otherwise it would have allocated more of the 2731MB that's allowed.
