Forza Horizon 6 now boots up in 4 seconds on Windows 11 PCs with AMD RDNA 3 and newer GPUs, a 95% improvement over previous load times. Microsoft credits its Advanced Shader Delivery (ASD) technology, which precompiles shaders in the cloud and delivers them to users before game launches. The change eliminates the need for on-device shader compilation, a process that previously slowed down first-time game loads and updates.
Shaders are critical for rendering graphics, but their compilation has long been a bottleneck. Every time a game installs or updates, the system must rebuild a shader cache, which can take minutes. Even minor driver updates often require recompilation, adding delays. ASD addresses this by storing precompiled shaders in a cloud-based Precompiled Shader Database (PSDB), tailored to each user’s GPU, game, and driver configuration.

The company first introduced ASD for Xbox ROG Ally handhelds last year. The technology has since been integrated into the DirectX SDK, with Intel and Nvidia also adopting similar approaches. The company’s inclusion expands ASD to RDNA 3, RDNA 3.5, and RDNA 4 GPUs, though availability remains limited to games downloaded via the Xbox PC app or Microsoft Store.
Forza Horizon 6’s performance with ASD is striking. On an RX 7600 GPU and Ryzen 7 5800 CPU, the game loads in 4 seconds—down from nearly 90 seconds without the technology. The improvement hinges on preloading shaders specific to the user’s hardware, bypassing the traditional on-device compilation process. This mirrors how consoles handle shaders, as they avoid hardware variability issues entirely.

The company and Microsoft developed ASD in collaboration, but the technology is currently restricted to RDNA 3+ GPUs. Nvidia users can use its “Auto Shader Compilation” feature, while Intel users have access to “Precompiled Shader Distribution” in its graphics app. Intel has not yet adopted ASD standards but plans to do so later this year.
ASD is available only to Xbox Insiders enrolled in the program, as the company treats it as a preview feature. At least 34 other games, originally announced for the Xbox ROG Ally, should support ASD immediately. The technology aims to eliminate one of the last major hurdles to instant game launches, especially as SSDs have already reduced traditional load time barriers.

Users without AMD RDNA 3+ hardware or access to the Xbox PC app must rely on Nvidia or Intel’s alternatives. Both companies offer shader management tools, though they differ in implementation. The company’s approach remains tied to its ecosystem, limiting broader adoption unless other platforms adopt the ASD standard.
The shift to cloud-based shader delivery reflects a growing trend in gaming optimization. By offloading compilation to the cloud, developers can reduce hardware-specific delays. However, the reliance on the company’s ecosystem and the preview status of ASD may slow its adoption beyond AMD’s current hardware lineup.
