> Epic Games integrates Microsoft's Advanced Shader Delivery into Unreal Engine 5.8 to eliminate shader compilation stutter on Windows 11.

**Unreal Engine 5.8** has introduced support for **Microsoft**'s **DirectX 12 Advanced Shader Delivery** (ASD), a technology designed to eliminate shader compilation stutter. First seen in development in 2026, the feature is now available for **Windows 11** PC developers.

The update includes an ASD Tool that generates a State Object Database from cooked builds, allowing shaders to be precompiled for specific GPUs before user download. It utilizes Partial Graphics Programs to reuse components across various graphics pipelines.

While it does not replace existing PSO precaching and currently lacks ray tracing support, ASD is expanding beyond the Xbox PC App. Microsoft confirmed future Steam support, while **Epic Games** targets an early 2027 arrival for the Epic Games Store platform.
