Nvidia has released GeForce Game Ready driver 621.01, adding support for Microsoft’s Advanced Shader Delivery technology. The update promises to eliminate the shader compilation stutters that have plagued PC gaming for years, at least in supported titles.
Advanced Shader Delivery works by offloading shader compilation to Microsoft’s cloud infrastructure. Instead of your PC building shaders locally — a process that causes lengthy loading screens and mid-game hitches — the system downloads precompiled shaders tailored to your specific graphics hardware and driver combination.
How the Technology Works
Using DirectX 12, Windows 11 and the Microsoft Agility SDK, developers capture shader information into a standardised State Object Database. Microsoft then combines that data with hardware vendors’ shader compilers in the cloud to generate a Precompiled Shader Database.
“Using DirectX 12, Windows 11, and the Microsoft Agility SDK, developers capture shaders into a State Object Database, allowing Microsoft’s cloud network to precompile shaders for hundreds of thousands of hardware and driver combinations,” explained Nvidia’s Andrew Burnes.
Key detail: The system is storefront-agnostic. Steam purchases benefit from Advanced Shader Delivery as long as the Xbox PC app is installed on your system.
Windows can then receive ready-to-run shaders rather than forcing your CPU to compile them locally. After a driver update, the shader cache updates automatically, eliminating the lengthy recompilation step that typically follows graphics driver upgrades.
Supported Games and Requirements
Two high-profile releases currently support Advanced Shader Delivery: Call of Duty: Modern Warfare 4 and Gears of War: E-Day. Both games must be launched through the Xbox PC app to access the feature, though Steam purchases work if the Xbox app is installed.
Nvidia claims a near-100 percent shader cache hit rate in supported titles, effectively eliminating mid-game just-in-time shader compilation. The result is no CPU spikes and no frame stutters when new effects or models appear for the first time during gameplay.
To benefit from the feature, you need Windows 11 24H2 or later and driver 621.01. The driver supports GeForce RTX 20 through 50 series GPUs and RTX Spark devices. Installing the driver alone won’t deliver the benefit — the game itself must support the technology.
AMD and Qualcomm Support
Advanced Shader Delivery is not exclusive to Nvidia. AMD already supports the technology in Adrenalin driver 26.6.1 and later. Qualcomm’s Snapdragon X2 series also works with the feature using driver version 2026.08.3 or higher.
Intel has announced support for both discrete and integrated graphics, though an official release date and driver version number have not yet been set. The cross-vendor adoption suggests Microsoft views this as a platform-wide solution rather than a single-ecosystem feature.
“With a near-100 percent cache hit rate, it eliminates mid-game ‘just-in-time’ shader compilation, wiping out CPU spikes and frame stutters in titles like Gears of War: E-Day and Call of Duty: Modern Warfare 4.” — Nvidia’s Andrew Burnes
Limitations and Caveats
The technology does not solve every performance hitch. Digital Foundry notes that Advanced Shader Delivery does not prevent traversal stutter, a separate phenomenon caused by data loading as you move through game worlds. Asset streaming, CPU bottlenecks and poor optimisation remain distinct problems that shader precompilation cannot address.
Developer adoption is another variable. Studios must specifically support the technology by building the State Object Database. If a game hasn’t implemented support, the new driver cannot help. Only two titles currently work with the feature, though Microsoft has promised broader Steam and Epic Games Store support is planned for later.
Early testing suggests the technology delivers on its promises for supported games. Users report that Gears of War: E-Day’s shader compilation step, which previously took upwards of 10 minutes on high-end systems, now completes in seconds. Whether that performance holds across a larger catalog remains to be seen.
