Microsoft’s New ASD Technology Reduces Game Loading Times by 95%
Microsoft has launched Advanced Shader Delivery (ASD), a technology integrated into the Xbox PC app that allows developers to distribute pre-compiled shader files directly to users. According to AMD, this system can reduce initial game loading times by up to 95% for supported hardware, with Forza Horizon 6 serving as the first title to implement the feature.
How does Advanced Shader Delivery reduce loading times?
Most modern PC games currently compile shaders locally on the user’s machine during the first launch. This process often results in loading screens that last several minutes while the CPU processes data for the specific GPU in the system. Microsoft’s ASD shifts this workload from the user to the developer.
According to Microsoft, the ASD technology enables developers to prepare shader files for various graphics cards in advance. These pre-compiled files are then delivered through the Xbox PC app, eliminating the need for the local machine to perform the compilation upon startup. This transition directly targets the “shader compilation stutter” and long initial wait times frequent in high-fidelity titles.
Which graphics cards support ASD?
The rollout involves close collaboration between Microsoft and hardware vendors. AMD has already released the Adrenalin 26.6.1 driver to enable ASD support. This functionality isn’t limited to the latest hardware; it’s backward compatible with several generations of GPUs.
AMD confirms that the following series are compatible with ASD:
- Radeon RX 9000 series
- Radeon RX 7000 series
- Radeon RX 6000 series
- Radeon RX 5000 series
What is the real-world impact on games like Forza Horizon 6?
Forza Horizon 6 is the first game to utilize ASD, providing a benchmark for the technology’s efficiency. By using pre-compiled shaders, the game avoids the traditional “compiling shaders” progress bar that often delays gameplay for several minutes after a fresh installation or driver update.
AMD reports that in some instances, loading times are reduced by up to 95%. This represents a significant shift in how PC games handle assets. Instead of the CPU struggling to translate code for the GPU in real-time, the GPU receives instructions it can execute immediately. This reduces the load on the processor and allows players to enter the game world almost instantly.
Comparing ASD to traditional shader compilation
The difference between traditional methods and ASD is primarily where the computational work happens. In the traditional model, the burden is on the player’s hardware, which varies wildly across the PC ecosystem. ASD standardizes this by delivering a ready-to-use package.
| Feature | Traditional Compilation | Advanced Shader Delivery (ASD) |
|---|---|---|
| Processing Location | User’s local CPU | Developer’s environment |
| Initial Load Time | Minutes (Variable) | Seconds (Up to 95% faster) |
| Hardware Impact | High CPU spikes during boot | Minimal CPU overhead |
Frequently Asked Questions
Does ASD work on all graphics cards?
Currently, it is supported on AMD RX 5000, 6000, 7000, and 9000 series cards via the Adrenalin 26.6.1 driver. Support for other vendors is expected as Microsoft expands the technology.
Do I need to change any settings in the Xbox app?
No. ASD is integrated into the Xbox PC app and works automatically for supported games and hardware.
Will this make my game run at higher FPS?
ASD primarily targets loading times and initial stuttering rather than increasing the maximum frame rate. However, it creates a smoother experience by eliminating compilation hitches.
