Description from the author on Modrinth

What is the FastPBR Shader?

This is a fast shaderpack that still offers high-quality visuals and uses PBR atmospherics, hence its name.

PBR does not mean specular support, so do not confuse these terms despite this being a common misconception in the shaderpacks community.

Where can I download it?

How to install FastPBR

  1. Install Iris (with Sodium) or OptiFine for your Minecraft version: shaders need one of them.

  2. Download the .zip file from Modrinth. Do not unzip it.

  3. In Minecraft, open Options, then Video Settings, then Shader Packs, and click Open Shader Pack Folder.

  4. Drop the .zip file into that folder, pick FastPBR in the list and click Done.

  5. Shaders are heavy on the graphics card. If the game gets slow, pick a lower profile in the shader settings.
