Graphical or Performance Issues

Updated January 30, 2026

If you are experiencing crashes, visual glitches, or performance instability, the issue is often related to a conflict between optimization mods and your specific hardware.

For Fabric Modpacks

These issues are typically caused by Sodium or Iris Shaders. If your hardware is incompatible with these rendering engines:

  1. Locate your modpack’s /mods folder.
  2. Remove or disable Sodium and Iris.
  3. Restart the game to see if the issue is resolved.

For Forge Modpacks

Instability is often linked to the pre-installed optimization mods.

  1. Visit the specific Project Page for your modpack on CurseForge or Modrinth.
  2. Review the mod list to identify optimization mods (such as Embeddium, Canary, or Starlight).
  3. Remove these mods from your /mods folder until the issue is resolved.
