Minecraft Forums

I have a new computer with decent specs. After a few minutes, Minecraft becomes stagnant, like I just blew up a load of TNT. The FPS drops to 0 and it takes me about a minute to be able to log out of minecraft. It seems to happen at random and doesn't matter if I am generating new chunks or staying in a part of the world that I have had loaded for ages. No error message pops up and it never logs me out, it just sits at a basically still frame of minecraft and moves in a glitchy slow motion. I don't understand what the problem is, seeing as I can run Skyrim on this computer with no problems whatsoever.

Specs are:

Intel® Core™ i7-2600K CPU @ 3.40 GHz 3.39GHz
8GB Ram
NVIDIA GeForce GTX 660

I'm relatively new to computers so I don't really know what all of that means, so if I left something out please let me know. Also, the guy I bought the computer said it was "overclocked" to 4.6 GHz I believe. Please let me know if you have any suggestions on what to do about this problem.

Thanks!

EDIT: I do have Optifine installed, btw.

I've noticed this as well. Happens on late 2009 Macbook with 4GB RAM. OptiFine isn't installed, but uses Minecraft Forge. It started happening when I upgraded to 1.4.6 from 1.4.5. Something must have changed between the two.

To add to the OP's observed behavior, while the frame is frozen I can still look around. The game slowly (/slowly/) comes back up to speed.

I'll test this in vanilla when I'm not so tired. Seems like a bug. Annoying, but at least nonlethal.

Can't replicate. Does this happen when there aren't any modifications to the JAR?

Okay. You have a beast PC, just sayin'.

Try forcing Minecraft to run on your 660 (instead of it possibly running off your i7's integrated graphics) and also try using the Magic Launcher.

Thanks And I have tried running it on Magic Launcher. Same result. And how would you go about forcing it to run off of the 660?

This originally happened on plain old vanilla minecraft. I tried installing Optifine and Magic Launcher to see if that helped the problem, but it did not.

I seem to recall hearing something about Java 7 and performance. Do you have Java 7?

In my experience, I updated LWJGL and that helped the game run much better than installing OptiFine (which actually made performance worse). There are notes on the wiki about updating and quirks.

1. Try updating java
2. If you still have problems try installing the mod "Optifine", it makes most peoples FPS's way faster.



Hope I helped.

I did download Java 7. I'll try going back to Java 6 and see if that does anything. And thanks for the link. I'll be sure to read through that soon

Already tried the updating Java and installing Optifine :/ No luck so far. Thanks though!
