Microsoft is rolling out a major upgrade for PC gaming performance: DirectX 12’s Agility SDK 1.618 is now out of preview with Advanced Shader Delivery, a feature designed to finally tackle shader compilation stutter and painfully long load times.
For years, shader compilation has been a top culprit behind hitching, frame drops, and first-boot sluggishness—especially in many Unreal Engine 5 titles. Even powerful hardware hasn’t been able to escape the problem, leaving gamers waiting on patches and workarounds long after launch. Microsoft’s new approach changes the equation by delivering precompiled shaders at download time, aiming to bring console-like smoothness and faster starts to Windows gaming.
How Advanced Shader Delivery works
Instead of compiling shaders on your PC during the first run, developers will capture and package a complete set of shaders during development. The system revolves around a new asset type, the State Object Database (SODB), created programmatically from pipeline state object inputs inside the game engine. Storefronts can then compile these SODBs into Precompiled Shader Databases (PSDBs) and deliver them alongside the game, DLC, or updates. The result is a near-100% shader cache hit rate, drastically cutting stutter and reducing load times on day one.
What’s shipping now and what’s next
– Advanced Shader Delivery begins rolling out on October 16 for select titles on ROG Ally handhelds via the Xbox app.
– The feature is built into Windows 11 with DirectX, and support will expand across devices and storefronts over time.
– Other PC storefronts will be able to compile SODBs to PSDBs and distribute them just like the Xbox app.
What’s included in Agility SDK 1.618 for developers
– State Object Database (SODB) authoring and collection tools
– Offline compilers from hardware partners to precompile shaders without using local GPUs
– Game Installer Registration APIs to enable distribution and installation of precompiled shader data
Hardware partners are on board
– AMD: A developer preview plugin supporting the new workflow is available to help teams get started.
– Intel: Offline compiler and driver support is slated to arrive in November.
– Qualcomm: Collaboration is underway to bring Advanced Shader Delivery to Adreno GPUs.
– NVIDIA: The company says its work with Microsoft will help improve load times and deliver stutter-free gameplay.
Why this matters for PC gamers
This is a platform-level fix to a platform-wide problem. By moving shader compilation out of the player’s first-run experience and into the development and distribution pipeline, games can reach a stable, smooth state immediately—no more waiting for massive shader compilations or suffering through hitching in the opening hours.
What developers should do now
– Integrate SODB capture into the engine build process to ensure comprehensive shader coverage.
– Use offline compilers from hardware partners to generate PSDBs ahead of release.
– Package SODBs/PSDBs with the base game, DLC, and updates to maintain a seamless experience.
If studios adopt Advanced Shader Delivery broadly, PC gamers can expect faster load times, smoother frame pacing, and far fewer shader-related stutters across the board. It’s a big step toward console-like consistency on Windows—and it starts rolling out this month.
