Epic Games has added native support for Microsoft's Advanced Shader Delivery (ASD) in Unreal Engine 5.8. The feature appears in the official engine documentation and marks an important step toward addressing one of the most common complaints in modern PC games: stutter caused by runtime shader compilation.
What is Advanced Shader Delivery?
ASD is a DirectX 12 technology from Microsoft that lets digital storefronts deliver precompiled shaders together with the game download. Instead of the player waiting minutes (or suffering hitches during gameplay) while the graphics driver compiles shaders locally, the data arrives ready for that specific GPU and driver combination.
In Unreal Engine 5.8, Epic included the command-line ASD Tool. It generates a State Object Database (SODB) from a cooked Windows build. Supported stores then use that database to create GPU- and driver-specific Precompiled Shader Databases (PSDBs).
Current limitations
Support still has restrictions. It only works with Direct3D 12 games using Shader Model 6 and does not cover ray-tracing Pipeline State Objects. Epic recommends that developers keep the engine's existing PSO precaching systems enabled, as ASD complements rather than fully replaces local caches.
Currently ASD is primarily available on the Microsoft Store and Xbox PC app on Windows 11 24H2 or higher, with support for AMD (RDNA 1–4), Intel Arc B-Series and Core Ultra, Nvidia RTX, and Qualcomm GPUs. Microsoft has already signaled expansion to Steam and the Epic Games Store, with Epic Games Store support expected in early 2027 according to Epic's documentation.
Why this matters
Shader stutter is one of the most frequent complaints in Unreal Engine 5 PC launches. Reducing or eliminating it on first launch and during gameplay directly improves the player experience and can shorten the long “shader compilation” screens many titles still show. For developers, native engine integration makes adoption easier without complex workarounds.
