For stability and especially security reasons, I would strongly suggest you update your Java to the latest 1.7.0_60 version http://www.java.com/en/download/.

• When using a 32-bit browser on a 64-bit operating system the automatic version detection will only show the 32-bit version of Java, the 64-bit version needs to be downloaded manually: http://www.java.com/en/download/manual.jsp.

Updated Java, no joy. 64bit manually.

The java was a suggestion for stability and security reasons (out of date java is currently the #1 attack vector for hackers). The ticket is still a duplicate of MC-61059

Sorry about the duplicate, I pushed the "Report to Mojang" button and figured that it was a different category of report.

Some trouble shooting

Prior to loading the world, I:
Changed render distance to 2 Chunks
Framerate to 30fps
Mipmap Off
applied /gamerule randomTickSpeed 0 and the game world loaded. Several textures blink in the distance.

Once in the game I changed back to 16 chunks, Unlim Frame rate and MipMap 2 and the game stayed loaded and blinking stopped. Game seems stable for now.

I set /gamerule randomTickSpeed 3 and the game crashed.:

Can't get the game to load again using the same method.
