Is Minecraft still slow?

Secret-chest edited this page May 22, 2023 · 1 revision

If Minecraft is still slow after installing this modpack, you can try the following suggestions:

1. Increase allocated memory

By default, launchers allow Minecraft to use 2 gigabytes (2048 megabytes) of RAM. You can increase this amount, but please leave at least 4 to 6 gigabytes of RAM unused, if you can.

Computer RAM Suggested allocated RAM
4G 2048M
6G 2048M to 3072M
8G 4096M
12G 6144M to 8192M
16G 6144M to 8192M
24G+ 8192M to 12288M

Increasing the memory in MultiMC

  1. Right-click your instance and select "Edit Instance".
  2. In the window that appears, click the "Settings" tab.
  3. Check the "Memory" option to overwrite it.
  4. Set the maximum allocated memory to your chosen value in megabytes.

Increasing the memory in the vanilla launcher

If you really want to use it (check below why you shouldn't):

  1. Make sure you're on the Java Edition page.
  2. Select the "Installations" tab.
  3. Click your installation
  4. Click "More Options"
  5. Under "JVM Arguments", find "-Xmx2G" and change "2G" it to your chosen value (G for gigabytes, M for megabytes)

2. Switch to a lighter launcher

The default Minecraft launcher is very heavy, and so are some popular launchers such as GDLauncher or even CurseForge. The recommended way to install this modpack is using MultiMC, which is very light and fast, and also supports modding natively.

3. Close other applications

This is self-explanatory.

4. Turn down your settings

In general, these settings have the highest performance impact:

  • render distance
  • simulation distance
  • max shadow distance
  • quality settings (graphics etc.)
  • particles
  • cull leaves depth
  • mipmaps

You can also turn down fullscreen resolution, or play in a smaller window.

Also try setting Max FPS to Unlimited (260) and disabling V-Sync.

5. Play on a server

Playing on a server offloads the game logic to said server, allowing your PC to focus on rendering.

This includes using another computer to host a world, even if you just want to play alone. You can also try Aternos, a free server host. Note that the server goes offline after five minutes without players.

6. Uninstall bloatware (malware)

Many computers come with bloatware, such as "ROG Armoury Crate" or other tools installed by the manufacturer. Uninstalling it removes background processes, so your system can focus more on Minecraft.

7. On Windows 7, disable Aero

Aero is the name of the Windows 7 visual effects. These effects are very resource-intensive; if you do not have a high-end computer you shouldn't use them.

8. Update your OS and drivers

9. Switch to Linux

Linux desktops generally run Minecraft about 2 times faster than Windows! A good distro to try is Linux Mint, however, switching your OS is a big undertaking; please do your research. For example, Adobe software doesn't run on Linux.

If you decide to keep Windows, you should look into dual-booting, which is a practice that installs both operating systems on the same system and allows switching between them when you turn the PC on. Dual-booting does not run both OSes in parallel.

10. On Macintosh, disable Retina (add the retiNO mod)

Recent Macintoshes have very large displays, with a very high pixel density. This is called Retina. The retiNO mod halves the resolution of Minecraft, making it run faster.
