MC-2434Huge lag spike renders game unplayable
After exploring a very large section of the map and creating around 77,000 chunks, if I move back to pre-rendered chunks a short distance away the framerate drops down to 0 FPS and will move one frame only every few seconds. Closing the window and reopenning fixes this problem, but it will persist continuously after moving a distance. This is very frustrating when you have distant mines and minecart systems.

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.

LOADS of people are experiencing this but no one seems to care. I totally agree that this is frustrating cause I have this problem too, especially in a developed area.
Creating 77,000 chunks is not a reliable way to reproduce this bug. Care to see if it's biome related, distance related, or mob count related?
In some LP videos, they would experience temporary severe lag issues while they are just building/mining stuffs. Usually, when it lags, they are near spawners. I may not be correct, but it's a good direction to look into seeing if spawning mobs and loading chunks at the same time may be causing the issue.
Please post more information in regards to your system configuration, such as graphics capabilities, RAM (and allocated to game), java version, etc.
