Java version Info:

Java 7u25 (tried with u45 too) x64bits
Started of with 7u45, tried jvm commands, didn't work, read somewhere that 7u25 might help, downgraded, no changes.

FTB Launcher Info:

1.3.2
And installed in recommended directory (from Booker The Geek's help thread: http://forum.feed-the-beast.com/threads/how-to-solve-your-own-issues-not-for-noobs.32555/)


Console log:

Running FTB Launcher with jvm commands recommended by Eyamaz in http://forum.feed-the-beast.com/threads/jvm-arguments-for-modded-minecraft-updated-11-11-13.28994/

At 2Gb allocated RAM: http://pastebin.com/GXdbNkeY
At 4Gb allocated RAM: http://pastebin.com/CywpdStW


The Issue:

Without Eyamaz's recommended jvm commands at any RAM above 4GB: Loads fine, plays fine for about a minute, starts to stutter and lag up to the point of being unplayable.

With Eyamaz's recommended jvm commands at 4Gb RAM: Again loads fine and plays fine for about a minute, starts to lag and stutter and eats up 10+Gb of RAM. See second log.

With or without Eyamaz's recommended jvm commands at 2Gb RAM: Runs out of memory as seen in the first log.
 
Surely someone here knows how to fix this, no? Or at least provide me with some info about why this is happening.
 
Well first of all: remove every single Java on your computer. Then only install J7u45. You don't need every version of Java 7 available, just u45.
