Before downloading the update, ensure your workstation or gaming rig meets the following hardware specifications: Minimum Requirement Recommended Specification Windows 10 (64-bit) / macOS 12 Windows 11 / macOS 14+ Processor Intel Core i5 or AMD Ryzen 5 Intel Core i7 or AMD Ryzen 7+ Memory 16 GB or 32 GB RAM Graphics DirectX 12 compatible GPU NVIDIA RTX 30-series / AMD RX 6000-series+ Storage 2 GB available space (SSD) 5 GB available space (NVMe SSD) How to Safe Download Shader Iteration 3.0.0

to start building the next generation of visual experiences.

Once downloaded, move the ZIP file into your shaderpacks folder inside your Minecraft directory.

Upgrading mid-project can sometimes cause broken dependencies. Follow these rules to protect your work:

Fix: Your GPU drivers might be outdated. Perform a clean installation of your graphics drivers using Display Driver Uninstaller (DDU) and update to the latest game-ready drivers.

Reduces VRAM overhead by up to 30%, preventing micro-stutters in asset-heavy scenes.

This is a high-end "ultra-realistic" shader. If you experience lag, try lowering the Render Quality or Shadow Map Resolution in the shader settings.

This is a confirmed incompatibility. If you wish to use Distant Horizons, you must either disable it or switch to a different shader pack such as the newer IterationRP, which supports Distant Horizons.

Which are you installing this shader into? What graphics card model is your PC running?

NVIDIA GTX 10-series / AMD Radeon RX 500-series (DirectX 12 / Vulkan 1.2 compatible) RAM: 8 GB Storage: 500 MB available space Recommended Specifications OS: Windows 11 or macOS Sonoma

Writing cross-platform shaders can be a logistical headache. The new compiler toolset automatically generates optimized fallback code for older feature levels, ensuring your visual effects look uniform across varying hardware tiers.
