Alpha Piscium uses cutting-edge graphics technology that places real demands on both your GPU and its drivers. Before installing, confirm that your hardware and software meet the requirements below. GPU vendor support in particular is not uniform — one vendor is entirely unsupported, and another requires a specific minimum driver version to function correctly.Documentation Index

Mod Loader & Shader Loader
Alpha Piscium is loaded through Iris, a dedicated shader loader for Minecraft. Iris version 1.7 or higher is required. Earlier versions of Iris do not support the rendering features Alpha Piscium depends on and will fail to load the pack.Download Iris
Get Iris 1.7 or higher from the official Iris website. The installer sets up a ready-to-use Minecraft launcher profile.
GPU Requirements
NVIDIA — Supported
NVIDIA — Supported
Modern NVIDIA GPUs are fully supported and represent the primary development and testing target for Alpha Piscium. Any recent NVIDIA discrete GPU with a current driver should work without additional configuration.For best results, keep your NVIDIA driver up to date via GeForce Experience or the NVIDIA driver download page.
AMD — Supported (Driver Version Required)
AMD — Supported (Driver Version Required)
Modern AMD GPUs are supported, but your driver version must be newer than 22.7.1. Older AMD drivers contain OpenGL bugs that prevent Alpha Piscium from loading or rendering correctly.To check your current driver version on Windows, open Device Manager → Display Adapters, right-click your AMD GPU, select Properties, and navigate to the Driver tab.
If you are on an AMD GPU and experiencing loading issues, open AMD Software: Adrenalin Edition (or download the latest driver from AMD’s driver page) and update to a driver version newer than 22.7.1 before attempting to run Alpha Piscium.
Intel — Not Supported
Intel — Not Supported
Intel GPUs are explicitly not supported. Alpha Piscium uses cutting-edge OpenGL features, and Intel does not maintain their OpenGL driver to the standard these features require. This applies to both Intel integrated graphics (e.g., Intel Iris Xe) and Intel Arc discrete GPUs.There is no configuration or workaround that enables Alpha Piscium to run on Intel hardware. A dedicated NVIDIA or AMD GPU is required.
Optional: Distant Horizons & Voxy
Alpha Piscium supports integration with Distant Horizons and Voxy, mods that extend Minecraft’s view distance using Level of Detail (LOD) rendering. If you have either mod installed alongside Iris, Alpha Piscium will work with their extended terrain rendering.Voxy users must use Voxy 0.2.6 or higher. Earlier versions of Voxy are not compatible with Alpha Piscium’s integration.
