FTB....WHY?

[FMAylward]

Sit back and relax a while, and let me tell you a story...a sad story of OptiFine and how it loved sending me for unexpected visits to the desktop.


Launch FTB
Go to the Options menu from the main Minecraft screen.
Go to Video Settings
Find the option called "Chunk Loading"
Set it to anything that is NOT Multi-Core.

Also, if you have an nVidia GPU, go into your nVidia control panel and disable threaded optimization.

Good luck!

I thought the only version that worked with FTB were the versions that couldn't do multi core? Though I am useing nvidia so will try that fix.

A lot of folks have been suggesting downgrade to this version or don't use ultra or whatever, but the word I got was that you should be using the most recent version of OptiFine Ultra that was made for 1.4.2, which is OptiFine_1.4.2_HD_U_A7. I apologize that I can't link you to a source for the statement naming that version, but what I can tell you with absolute certainty is that that is the version I'm using, and my crash problems ceased immediately as soon as I disabled multi-core chunk loading.

Installed that version, I'll see how it goes and post here.

Though the chunk loading option would explain the crashes I got before as they seemed to happen when I started walking long distances.

I had ugly nasty horrible frustrating insta-crashes for a while. These are the steps I attempted to fix it:

Clean install of Java 7.9 (I'm on PC). A very serious pain to get a proper clean install of Java 7.9 for 64-bit Windows 7. No fewer than 3 applications promising to fully and properly uninstall Java and all of its grubby little tendrils were tried until I finally found some obscure little app that got the job done. It was during this time that I learned Mozilla had abandoned support for 64-bit Firefox, meaning that when I updated Firefox to the latest version it actually reverted to a 32-bit application and the detection applet on the Sun/Oracle/whatever site where you download Java kept giving me 32-bit Java as a result. Eventually, I was the proud owner of a clean 64-bit Java 7.9 install and it did absolutely nothing for my problem.

After poking and prodding google for a while, I learned that perhaps I had gotten a wonky version of lwjgl (Light Weight Java Games Library, an integral part of Minecraft) so I found, downloaded, and installed the most recent version. Still no luck.

Ultimately I found myself on the OptiFine thread at the official MC forums where I was sadly not surprised to find that a dozen or more solutions had been presented and none of them worked.

And then, off in some far flung corner of the interwebs I found a glimmering little tidbit, the foretold solution and the key to my victory over the bitchy little nemesis that is OptiFine:

Launch FTB
Go to the Options menu from the main Minecraft screen.
Go to Video Settings
Find the option called "Chunk Loading"
Set it to anything that is NOT Multi-Core.

Also, if you have an nVidia GPU, go into your nVidia control panel and disable threaded optimization.

Good luck!
