Nvidia's 621.01 driver adds Advanced Shader Delivery support; Modern Warfare 4 and Gears of War: E-Day are among supported games

What players need

Digital Foundry says Nvidia users need Windows 11 24H2 or later and driver 621.01. VideoCardz reports that the Xbox PC app is also required. VideoCardz places Nvidia's hardware support across GeForce RTX 20 through 50 series GPUs and RTX Spark devices, but says installing the driver alone will not deliver the benefit without a supported game.

There is a storefront wrinkle. The Verge quotes Nvidia's Andrew Burnes saying Steam purchases can benefit if the Xbox PC app is installed. VideoCardz says the precise availability through other storefronts remains unclear, while Neowin reports that broader Steam and Epic Games Store support is planned for later. That is not a promise that every Steam game can download these shaders now.

Nor is it a cure for every hitch: Digital Foundry says the technology does not prevent traversal stutter, which occurs as game data loads while a player moves through the world. Separately, VideoCardz lists fixes in driver 621.01 for crashes in Wuthering Waves when Freestyle filters and DLSS Frame Generation are enabled, and in Star Citizen when using Vulkan.
