Why does using Technic Launcher modpacks slow Minecraft down?

Why does using Technic Launcher modpacks slow Minecraft down? - Bearded worker using tablet while standing near workbench in workshop

I can play normal Minecraft at 60 FPS, on the highest settings. When I launch a Technic Launcher modpack, Minecraft will run at a maximum of 4 FPS.

I have a Qosmio gaming computer, running Java 7 64-bit. It will not run at all with Java 8 64-bit. I have allocated 7GB of RAM, and tried setting all the settings to the lowest possible configurations;

  • Render distance: tiny.
  • Clouds: off.
  • Particles: minimal.
  • Smooth lighting: off.

Can someone please tell me what I am doing wrong, and how to fix it?



Best Answer

Have you checked your RAM allocation? I haven't used Technic in years, but I assume it still defaults to 1GB. Try upping that (there should be an options menu before on the launcher)

    Answer 2

    We released with a bug that causes Technic to eat up CPU on one core while Minecraft is running. Depending on how many cores your machine has, this could have very serious consequences for playing Minecraft. There is a fix on the Beta stream, so you can try Launcher Options -> Launcher Build -> Beta Stream and see if your performance improves.

    Answer 3

    Launch Technic Launcher, then click on launcher options at the top right. Explore the options until you find RAM, The most RAM you can use is 5 GB on technic. Hope this helps :)
