Why does Minecraft stutter so much?

[AstroBenny]

I hate to be that guy who plays Minecraft but I haven't really touched it in a while but now I remember why!

It runs awfully

Sometimes on a Vanilla world I can get upwards of 500fps but it will still stutter.

Other times I'll struggle to get over 60fps but the game still stutters regardless.

I'm referring to stuttering in the sense of "juddering" every few seconds or so.

I've installed Optifine and it's greatly improved but it still stutters every 10 seconds or so regardless of fps..

I had the same issue on my last PC and the issue is present on my current system so this seems to be a universal problem..

How could anyone even play the game in its unmodified state? It's awful..

Specs:

4690K

8GB Corsair Vengeance 1866Mhz

GTX 970

Maximus VII Hero

AX760i

Windows 10

 

AM I THE ONLY ONE??

java is the reason

Because minimum fps dips when shit loads. Java things. 

 

Runescape stutters too even though it runs at 50 fps and on a beast of a computer.

java is the reason

 

Congrats on 1,000!!!!

Congrats. But how can I improve it?

[Gikero]

I use Java 64-bit, installed a secondary drive. I've got some graphical mods and overall the game is smooth. It does lag, for a moment, if it has to render a spawn something huge.

Have you watched your GPU usage while playing it? Sometimes the drivers won't recognize Minecraft as a game and won't give it the horsepower needed to run smoothly.

 

This is just my guess, I'm not an expert by any means.

go to edit profile and REMOVE "Xmn=128M" from the arguments. leave everything else alone

the game is badly optimised. its kinda old too. so ye.

My utilisation of the GPU is only at 20-30% but from my understanding, Minecraft is a CPU intensive game.

However, is there a way to make sure the 970 is being utilised?

Look into allocating more ram if you haven't yet. 

I use about four GB and it stopped shuttering

Afaik if it's being output to a display through your graphics card then it has to render it with that. On a desktop that's the default. On gaming laptops, sometimes you have to actively select the graphics accelerator you want to use each time.

 

The reason for the stuttering is because they decided to use Java.

[TomvanWijnen]

You need to allocate more RAM (I suggest 4GB), I'm 99% sure that will fix your problem.

Other than rewriting the game yourself in a real language, there's nothing you can really do, other than make sure you've got 4GB dedicated, vsync off, optifine installed and configured right (i think defaults are good enough though) and make sure you're not loading maps off a 5 MB/s flash drive

Thanks. But would increasing the memory limit to 4GB actually make a difference if the game is only using 20% of the unmodified RAM amount the game has already defined to use?

I don't know how it could be using so little, but I look at it as one of those "it can't hurt" things.  You've got enough RAM to afford giving it 4 GB, and I'm pretty sure I've seen it make a difference in the past.

These are all good calls ^^^^^^

 

However, I find that with some newer GPU's, Optifine gives me worse results than without it.

[AstroBenny]

Surely Mojang has enough money under their belt to make to the game playable though?

I should also mention running a recent version.  They went through a pretty long period there were everything was terrible (from around 1.2.something I think - when they abolished the dedicated singleplayre "server" and introduced using the multiplayer server for everything), and when it was suddenly smooth and playable again (around 1.8 I think, may have been earlier - can't remember), it was amazing!

$2 billion vs the infinite power of Java?  I don't know...

Also, since Minecraft downloads only 32 bit Java on almost any PC out there, you may want to download 64 bit java. This will considerably increase performance.

Yes, and for some reason that's necessary to go over (or even get to in some cases) about 2 GB of RAM usage, so if you want to dedicate 4 GB, it is a must.
