What is the Simplicissimus Shader?

As you might have already guessed from it's name this shader is very simple and thus also performant. It only does some little touchups to the vanilla graphics and adds dynamic shadows.

For the same reason a lot of the vanilla stuff remains intact, like lightmaps or clouds.

 

A recommended resourcepack is the Bare Bones resourcepack with it's accompanying Normals and Specular Add-On.

 

What features does it have?

  • dynamic shadows
  • bloom
  • motionblur
  • temporal anti aliasing
  • wind effects
  • soft shadows

 

Any requirements?

Optifine for 1.12 or newer

A graphics card supporting OpenGL 2.1

Should work on Windows, Linux and Mac

 

Where can I download it?

Either here or via my website (link below).
