 Description   

What I expected to happen was:
New chunks should load as previous to 1.4.6, and I should be able to fly over them in creative mode.

What happened:
New chunks were not created, causing the game to crash as I flew.

Steps to reproduce:
Graphics FAST
Render NORMAL
Smooth lighting OFF
Anaglyph OFF
Performance POWER SAVER
View bobbing OFF
Advanced OpenGL ON
Clouds OFF
Particles MINIMAL
VSync OFF

Large biomes, structures on, cheats on

Stay within 10000m from spawn
Fly over DESERT

The world where I noted this to occur was created after version 1.3.

Additional:
Due to a moderately slow machine, new chunks sometimes take a long time to load. Since 1.4.6, if this happens while flying, especially over desert terrain, MineCraft may crash entirely if a chunk does not load before entering. I have not ventured more than 10000m from spawn.

I have not had this issue with previous updates, and have had to significantly downgrade the quality of render to make MineCraft playable on 1.4.6 update for either survival or creative. I have included 2 relevant crash reports.

Is this a bug, or a glitch due to a slow machine?

No more updates, assuming no longer an issue.

Don't listen to the bot...

I could not find any existing issue that contains any of the crashes mentioned here. However, all of the crash reports that you have provided are from a modded version of Minecraft. Please try to reproduce the crash in a vanilla (non-modded) version of Minecraft and attach that report or this may be dismissed as being caused by a mod. You can view all information known about this specific crash at MCX-224.

Don't know, didn't test it before I got a much higher powered machine.

Comment by Tails [ 07/May/13 ]

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.

Xavier Brown's advice is good for stability, though it makes the game run slow sometimes. I suspect the max fps setting means the render doesn't try to cheat on falling blocks - note that I specified desert terrain.

Thanks to the fact that I have a notebook, the application of an ice pack to the heat exchange is quite effective and means I can render at normal distance safely. However, this is brute-force hacking, rather than an elegant solution.

Try using Max FPS instead of Power Saver. It frequently crashed my game on an older machine.

Not sure if duplicate of MC-509, but still related.

Comment by Jay Ayerson [ 23/Dec/12 ]

Thanks Kumasasa.

I did try searching for this. I hope I haven't wasted your time, as it was not clear from my end (as someone with only modest references to technical programming) that it had any relationship to a previous problem.

This is a duplicate of MC-509 - which is about dedicated server, but the crash is the same.
