Pixelmon Lag Issue

If you’ve encountered any lag problems once you installed the recent update, you should ensure that the settings you’re playing Pixelmon are right.

The default Java version installed in Windows is 32-bit whereas you need 64-bit Java to run Pixelmon. Pixelmon can be pretty irritating with the lag problems because of the many creatures spawning from all directions, it’s like their main function is to bring down the Frames Per Second (FPS). If you’re looking for a functional way to rid yourself of this annoying lag problem, this guide will prove helpful to you.


Step 1: Dedicate More Ram To Pixelmon

Starting off, you need to check how much RAM your PC has. You’ll have to open the System Properties by right-clicking This PC and selecting Properties.

Checking up the RAM
Checking up the RAM

The RAM will be described next to the Installed Memory (RAM) section. As you’ve determined the amount of RAM installed in your PC, now it’s time to dedicate more RAM to Pixelmon.

  1. If you’re using the Technic Launcher, first open the launcher and select Launcher Options from the upper right.
  2. Now open the JAVA SETTINGS option.
  3. In the Memory dropdown menu, enter the amount that is equal to the half of the RAM that is installed in the PC.
  1. On the other hand if you’re on the common Minecraft Launcher, you should open up the launcher and choose your Pixelmon profile.
  2. Click the Edit Profile option situated on the bottom left.
  3. Click the textbox for JVM Arguments, clear up any text in it and type in   Xmx6G -Xmn128M.
  4. G6 can be changed depending on the amount of RAM you want to enter, eg: 4G for 4 GB and 2G for 2 GB.

Step 2: Increase Power Output

One of the major reasons why Pixelmon lags is because of low power output – especially on laptops.

To increase the power output to reduce Pixelmon lag, make your way to Control Panel -> Power Settings. Finally choose the High Performance option.


Step 3: Change In-Game Settings

Now that we’re done with dedicating more RAM and also have set the Power Settings appropriately, it’s time to change the native game settings. Launch Pixelmon and go to Options. Now open Video Settings and make changes as shown in the image below.


It’s time we explain the effects brought about by the most important changes in settings in the lines below. Read on.

  1. Graphics: These settings control how high / low the game’s graphics appear. You should set it to fast to achieve max FPS.
  2. Render Distance: This setting determines the visibility range for you, i.e. how far you can see. Change this setting to whatever suits you the best but keep in mind that the lower it is, the higher FPS you’ll get.
  3. Smooth Lighting and Smooth Lighting Level: These settings control the working of the lighting and the shadows. It’s better to keep them OFF to get max FPS.
  4. Max Frame Rate: This controls the number of FPS (Frames Per Second) that are displayed on the screen. It’s better to keep this at 60 or VSync, whichever is more suitable for you.
  5. Advanced OpenGL: This setting is about how the shapes and geometry of the game are rendered. It is better to set it to Fast.
  6. Chunk Loading: fF your PC has a multi-core processor then set this setting to Multi-Core.
  7. In Details, you can turn off the Rain and Snow to further smoothen up things.


Step 4: The Mods

If you’re using a PC with low specifications then you should use either the Optifine or Fastcraft mod along with Pixelmon which pretty much help in increasing the speed of the game. They also help in preventing the loading of unnecessary stuff Minecraft. One more thing that can help you is removing all the other useless mods that you may have installed previously because sometimes they are indeed the reason your game lags.
