Minecraft is yet again, being stupid.

Hi, I have a very high end gaming pc. (AMD FX 6300, AMD Radeon 7950, 16 GB of RAM, and 1.5 TB of space.) But Minecraft has been making me so angry lately. I get in-game, and I get micro-studdering every half-second! It goes from 60 and drops to 2-1 and is literally unplayable. What's going on? There is nothing wrong with my hardware whatsoever, and the last time this game worked correctly I got 110 fps constant with minimal studdering. Somebody please help.

First, just being clear, that CPU is not "very high end". It trades blows with the i3-4150 in games. Both are great CPUs for the price, but I'd never call them very high end.

How long ago did you last play Minecraft when it worked correctly?
Are you using HD texture packs, and do you have the 64-bit version of Java installed?
Are you using any framerate limiting software such as Fraps or DXtory? (Java hates that)
Your framerate target in the Minecraft options should be set to much higher than 60 fps, if you intend to hold 60 fps.

How much RAM is allocated to your game. It needs at least xmx... Or xms? 1024. 1gb at absolute minimum. You'll find the info in the profiles area of the minecraft loader. But don't go crazy and starve your system by giving the game all but your last gb of RAM. Otherwise you'll only encounter other problems.

Hope this makes sense.

To add up on what SoupNutz said, those are Java Virtual Machine launch arguments which define how much memory the application has access to.

I don't play minecraft, but for how cpu and memory intensive it seems to be, I'd try setting these variables. It's a Java application, after all...
-XX:MaxPermSize=256M
-Xms=512M
-Xmx=2048M

That will make it run with a base of 512mb of memory, eventually getting up to 2gb if needed (unless you're using hd tex packs or external shaders I doubt you'll need more). It'll also increase permanent data's space to 256mb, which should make things slightly more responsive.

These settings are also pretty good to add if you want a more intelligent memory management, but may get things slightly unstable if minecraft works by assuming these aren't enabled...
-XX:+UseConcMarkSweepGC
-XX:+CMSPermGenSweepingEnabled
-XX:+CMSClassUnloadingEnabled

Either way, your cpu isn't exactly high end, and minecraft requires a lot of beef from that, so don't expect miracles out of it.

The last time it worked correctly was during version 1.7.8. I haven't really played it lately. CS:GO took over my life.
No, am using default texture pack, nothing fancy, and yes I do have 64-bit Java.
I have fraps. But whenever I open it Minecraft doesn't even run, so I just keep it closed.
My framerate target is unlimited, so that's not the issue.

Also, the 6300 actually statistically blows the i3 out of the water, and performs more like a core i5. Trust me I know from experience. But I really don't want to start a fight so I'm just going to leave it at that.

The FX-6300 is not actually stronger than the i3-4130 or the i3-4150. They trade off from game to game, as you can see. I was annoyed by other factors in my life earlier, sorry for getting snippy. I've edited this post.

As to Minecraft, it takes what, like 15 seconds to re-download? I suppose you've already tried deleting it and re-downloading?

Lol I'm detecting some fanboism here. His AMD-Radeon rig is fine for minecraft. However. It might be Fraps messing with your game. I think if you press F3 you get your onscreen coordinates (X,Y,Z) etc. Plus frame rate. I think I was told by a guy on here. That fraps doesn't always like some games.

Never said it wasn't fine for Minecraft; he said he was running it fine before. I'm just contesting his claim that it was very high end, to keep things accurate for other readers.

Ok. I give. Just looked like a bit of fanboi fire going on. I don't know squat about AMD or ATi. Not since Phenom 2's and the 5870 series ATi cards.

I do think the op should try the f3 key. Tell us what the memory usage is. And then try it again without Fraps.
