Visual guide to allocating RAM

From Pixelmon Wiki
Revision as of 08:42, 25 January 2018 by Xpand (talk | contribs)

By default, Minecraft starts up with only 1GB of memory to work with. Pixelmon requires a bit more to work smoothly; 1500MB at minimum, with 3GB often being considered ideal. If you're experiencing a lot of lag or the game is not starting, try using this quick guide to change the allocation.

Minecraft launcher

Step Example
Start the Minecraft launcher.

Replace "-Xmx1G" with a higher amount,

such as "-Xmx3G" (or "-Xmx3000M")

Your allocation is now set, and the game should now be ready! If your launcher is not letting you allocate more than 1GB, get a 64-bit Java download for your operating system from here, and then restart your launcher.

If you get stuck on any of these steps, or you are having trouble finding the right amount to allocate or getting the game to perform smoothly, feel free to ask for help in the official Pixelmon Discord.
