Setting your allocated memory and launch options

Allocating more memory for Minecraft can greatly increase performance, but too much memory can also cause problems. If you have little memory installed, make sure there is enough for your system.For the best choice how much memory to put for minecraft look below and choose the best for comfortable game play:

  • 2 GB (Suitable who play on low graphics and rendering)
  • 3-4 GB (It's good for a regular game of minecraft)
  • 5-6 GB (Suitable for playing with shaders, high rendering distance,high-resolution resource pack etc)
  • 6+ GB (Not recommended unless you're a psycho)

Don't forget to leave memory for the system

If you have problem lag and freezes you can use the launch options for Minecraft (ShenandoahGC)
