How much RAM the game uses to run. When Minecraft is modded, it uses more than the default 1GB of RAM. You can make Minecraft use more than 1GB of RAM by clicking Launch Options, then enable Advanced Settings, then click on your Profile you use the Forge version with, enable JVM arguments and left from it you should see a text box filled with mostly stuff I don't know why they are there. The first thing you see if you read from right to left will be "-Xmx1G...". I don't know what the first letters are for, but the "1G" means that your game uses 1GB from your total amount of RAM. You can change the number representing the amount of GB used to whatever you want, but don't do let's say 16GB/16GB, if we presume that you have 16GB of RAM, like me. If you do that, either your OP will crash, because there isn't enough RAM to support it, or the game will simply not allow. I use a lot of mods, so I set my GB use to 9, but if you don't have a lot of mods, you can change it to 2, 3 or 4GB.
