MC-4349Game freezes for few seconds every so often
In random time intervals, Minecraft takes 100% load on all cores and completely freezes for a couple of seconds. Freezes come in series, i.e. they happen more common for a few minutes and then become less frequent.
They happen in Vanilla singleplayer, no idea about multi.
Tested sound, checked if it is chunk saving and it seems uncorrelated to those.
I would put my bet on light calculation, it may be happening during sunset/sunrise and on new chunks generation, loading and refreshing. The freezes has been happening for a few versions now (since 1.4.2 I think), so it may be connected to code light fixes.
The issue seems exactly the same as MC-535. But that one was deemed "invalid" for allegedly being reported for modded Minecraft.

It seems snapshot 13w04a has a performance issue with HD texturepacks when Minecraft 1.4 didn't have any on same computer (but Minecraft 1.4 had more glitches and less features than 13w04a of course).
What happens is (in order):
- Smooth framerate during ~30 seconds
- Horribly laggy framerate during ~20 seconds (impossible to play)
- Smooth framerate during ~30 seconds
- etc...
The problem happens with a 128x up-to-date texturepack (optimized for 13w04a). However, the problem also happens with default texturepack but is less noticeable (it's just like a lag spikes).
The game doesn't crash so there is no crash-report.
Note:
- My LWJGL library is up-to-date.
- My computer (a dual-core one) has a good hardware and is able to run MassEffect3 without any problem.
- The problem is less noticeable (or shorter) when using a lower resolution of texturepack
- When the problem happens ingame, it also still happens in the main menu before stopping
- During the problem, one core is at 100% but the other is iddle.

What kind of graphics do you have on your system, and is the driver up to date?

Linux kernel version is 3.6.6
I will try running Minecraft using nvidia card, tooEdit:
Same using
GeForce GT 555M/PCIe/SSE2
driver: NVIDIA 310.19
by Bumblebee
Also, the freeze can occur during level loading, after server startup before "downloading terrain" shows up.
I also have this issue. Same symptoms (different freezeless time intervals, cpu 100%). After these freezes log message appears:
No mods, single player.
Linux kernel 3.6.11.
AMD FX8120, 8Gb RAM, NVidia GTX650 (310.19 driver).
Latest lwjgl binaries from developer site. Minecraft update 1.4.6->1.4.7
And now I don't have such freezes.
Is this still a concern in the current Minecraft version? If so, please update the affected versions in order to best aid Mojang ensuring bugs are still valid in the latest releases/pre-releases.
No answer on querry, assuming no longer an issue.
