What you can look forward to: Microsoft is preparing to expand its Advanced Shader Delivery service to PCs with Intel, Nvidia and Qualcomm graphics hardware, a move aimed at shortening the lengthy shader compilation process that can delay a game’s first launch. The service is already included in the PC version of Gears of War: E-Day, but currently only works with AMD Radeon GPUs. Microsoft says support will be available for additional Windows devices later in October.
Advanced Shader Delivery (ASD) distributes compiled shaders from the cloud, rather than requiring each player’s PC to compile them locally before playing. According to Microsoft, this can shorten the process from “several minutes” to “just a few seconds,” reducing overall burn time by 95%.
Shader compilation is now a well-known problem for PC gamers, especially in large games with demanding graphics systems. Shaders are small programs used by the GPU to render lighting, surfaces, effects, and other visual elements. A game may need to compile them for a specific PC setup before it runs smoothly.
This process often happens when you first start a game. In some cases this also happens during gameplay when loading new areas, effects or assets. When this happens, stuttering can occur even on high-end hardware.
Microsoft’s approach aims to shift more of that work away from the player’s computer. Instead of the PC having to prepare all shader data locally, ASD provides precompiled shaders via the cloud. The goal is to reduce both the initial latency and the risk of shader-related issues once a game is running.
Wendy Ho, DirectX program manager at Microsoft, said in a company blog post that the service will soon support “additional Windows devices with Intel, Nvidia and Qualcomm.”
Wider GPU coverage gives ASD a better chance of becoming a viable option for larger PC releases, rather than a feature tied to a narrower group of systems. Nvidia remains a major player in PC graphics, while Intel has expanded its Arc GPU offerings and Qualcomm is making further inroads into the Windows device market.
The initial implementation also highlights the scale of the problem Microsoft is trying to address. Gears of War: E-Day went through a significant shader compilation step at launch. Microsoft reports that Call of Duty: Modern Warfare 4 is the next game to support this technology.
The service does not automatically improve every PC game. Developers need to integrate ASD support into their titles, and there is no sign that it will become standard across the industry in the near future. Some games will still compile shaders locally, while others may use other caching or precompilation methods.
Still, shader compilation has become one of the most obvious weak points in the PC gaming experience. Gamers can spend a lot of money on fast processors, modern graphics cards, and solid-state storage, and then wait several minutes for a new game to appear on the menu. If ASD works as Microsoft describes it, it could speed up initial launches and reduce one of the most common causes of PC gaming stuttering.
