Microsoft to Eliminate Shader Compilation Wait Times in PC Games with Advanced Shader Delivery

Microsoft is working to eliminate the long wait times associated with shader compilation during the initial launch of PC games. According to reports from Ars Technica, the company presented an update to its Advanced Shader Delivery (ASD) technology for Windows at the Game Developers Conference (GDC 2026).

The Mechanism Behind Advanced Shader Delivery

PC gamers often face multi-minute delays when starting a new game as the system optimizes graphical effects for specific hardware. While console developers can pre-optimize shaders for fixed hardware, PC shaders often remain as uncompiled code that must be processed locally. ASD automates this by creating a shader database compatible with a wide range of drivers and GPUs.

Developers utilize the Direct3D API to form a Shader Object State Database (SODB), which describes game assets at the engine level. This database is processed by compilers to create a Pre-compiled Shader Database (PSDB). This PSDB is downloaded with the game and updated alongside new drivers, preventing the need for repeated local compilation.

Performance Gains and Industry Adoption

Microsoft first integrated ASD into its SDK last September and added support for the ROG Ally in October. This implementation resulted in an 85% reduction in launch times for the game Avowed, which is particularly beneficial for handheld devices with limited battery life.

The rollout across the PC segment is gaining momentum:

• NVIDIA is working to bring ASD support to GeForce RTX cards later this year.
• Intel is preparing a compatible driver for the near future.
• Qualcomm plans to include the feature in its Adreno X2 GPUs.
• Epic Games is conducting early tests for SODB and PSDB generation in Unreal Engine.

Microsoft has updated its API to simplify PSDB creation for large-scale titles. Starting in May, developers will be able to upload pre-compiled shaders via the Xbox Partner Center. While initially limited to the Xbox app on PC, Microsoft plans to make this technology available to all game stores in the future.
