The GPU scheduling function with hardware acceleration is able to redistribute CPU resources. Which theoretically can increase productivity. In practice, an increase in FPS and a decrease in latency are observed. Depending on the specific application or task.
This article will tell you how to enable Windows 11 hardware accelerated GPU scheduling. Of course, the technology has some limitations. This means that not all hardware will support it. Make sure you have the latest video driver installed…
What is Hardware-Accelerated GPU Scheduling
So, Hardware accelerated GPU scheduling (Hardware-Accelerated GPU Scheduling) helps reduce latency and increase performance. It takes the heavy lifting that your CPU usually handles and hands it over to your graphics processor.
- Introduced in Windows 10 version 2004 update; works with all versions of Windows 11.
- Requires NVIDIA Pascal generation and higher (from 10th series). Minimum driver version 451.48.
- With AMD driver Radeon Software Adrenalin 2020 Edition 20.5.1. RX 5600, 5700 and above models.
- Intel graphics cards will support the feature in the near future, so keep an eye out…
NVIDIA’s response: potentially improves performance and reduces latency by allowing the graphics card to manage its memory. The letters AMD: increases GPU responsiveness and delivers additional workload management innovations for the future.
- Reduce CPU usage. Offloading scheduling responsibility to the graphics card means that the CPU won’t be constantly creating the frame data that the GPU would normally need to process these requests, meaning less load on the CPU.
- Reduced input lag . Every millisecond of lag in a video game itself is time that matters. Since the GPU handles all aspects of graphics processing, the delay between a click and the corresponding action on the screen is reduced…
- Lower CPU temperature . Since the processor is under less pressure due to the switching of scheduling responsibilities, it will be able to work faster and longer without overheating. Less load, lower temperatures, and free resources for other tasks.
Enable GPU scheduling
On the menu “Start” click Settings > System > Display. In the accompanying parameters Graphics > Changing default graphics settings. Slider Hardware-accelerated GPU scheduling on incl. You can enter “GRAPHICS SETTINGS” in the search.
In the registry editor, the location HKEY_LOCAL_MACHINE\ SYSTEM\ CurrentControlSet\ Control\ GraphicsDrivers. Meaning HwSchMode establish on 2. If it does not exist, create a DWORD (32-bit) parameter. You will need to restart your computer for the changes to take effect.
How to check if GPU scheduling is working
For example, the TechPowerUp GPU-Z application can help us. Instead of Intel(R) UHD Graphics, I choose NVIDIA GeForce RTX 3080 Laptop. In the section Advanced > WDDMversion 3.1 and Hardware-Accelerated GPU Scheduling — On. Does not work with Radeon RX 580 video card: Off (not supported).
Conclusion
In practice, the performance increase for minimum FPS is up to 50%, and average up to 10%. It is recommended for use if the processor power is not enough. Since some tasks are transferred to the GPU, which reduces delays. Depends on hardware and software…
It’s interesting what Microsoft says: You’re unlikely to see any major differences in your computer’s functionality. This feature changes the way the GPU handles requests, and the system itself distributes tasks between the processor and the video card, taking into account their requirements.
