FastPBR
ModrinthA fast and high-quality shaderpack with realistic visuals and PBR atmospherics.
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.
