These days, gamers are familiar with having to wait for a few minutes during the “compiling shaders” stage when they first run a new game, as their hardware optimizes 3D effects.
Recently at the Game Developers Conference (GDC), Microsoft explained the progress of Windows Advanced Shader Delivery, a technology aimed at allowing pre-downloaded collections of compiled shaders.
In console environments, developers can optimize and precompile graphics shaders for specific drivers and GPU environments. However, on PCs, developers often leave shaders in an uncompiled state, which means they are compiled and cached during runtime to match the specific hardware and drivers on the player's PC.

Microsoft first implemented Advanced Shader Delivery in its software development kit (SDK) last September and added support for ROG Xbox Ally as a proof of concept in October. According to the company, this feature has reduced game startup times by up to 85% for games like Avowed. This is a significant improvement for handheld gaming devices where battery life is crucial.
However, the adoption rate of Advanced Shader Delivery across the PC gaming ecosystem has been slower. Nvidia has stated that it is closely collaborating with Microsoft to support this feature "within this year" for its GeForce RTX lineup, and Intel expects to release ASD-supporting drivers "in the near future." Qualcomm also announced that it will soon introduce this functionality on the Qualcomm Adreno X2 GPU.
Even with hardware-level support, game engine developers need to integrate Microsoft's SODB (State Object Database) API to simplify the process for game developers. Epic Games is "conducting initial tests and reviews regarding SODB and PSDB (Precompiled Shader Database) generation," but it remains unclear whether this represents a firm commitment to supporting Microsoft's vision.
