ErnestoHF wrote: what is   '-Xmx2G' and  JVM? When you start your Minecraft launcher, the first screen you get has a profile selection option to the bottom left. That is where you select the profile you need to play Forge modded client versions. Select a profile from the dropdown list. Then 'Edit profile', which opens a new screen with all info related to the selected profile. In the bottom row, under 'Java Settings (Advanced)', you can set the so-called 'JVM arguments'. the only argument or 'flag' I use is '-Xmx2G', which allocates 2 Gigabytes of memory to your Minecraft client upon launch. In most cases you don't need more and 2G is really needed for heavy mods like the LOTR mod.
