Scheduling Windows 10 hardware accelerated GPU

The hardware accelerated GPU scheduling function is actually intended to improve scheduling. Which should improve the performance of some applications at startup and not only. In practice, there is not only a decrease in latency, but also an increase in FPS.

This article will show you how to enable Windows 10 GPU scheduling. Basically, if at least one condition does not meet the requirements, then it will not work. Over time, the list of supported video cards will only expand.

What is this function and whether to enable it or not

GPU hardware acceleration Planning (Eng. Hardware-Accelerated GPU Scheduling) to reduce latency and increase performance. How it works? In theory, with it, discrete graphics independently manage their own video memory.

  • Right in the Windows 10 version 2004 update, there was a feature: GPU scheduling with hardware acceleration.
  • It works with graphics cards from the Pascal generation and above. Supported from driver version 451.48 (which also brought DirectX 12 Ultimate).
  • AMD graphics cards require at least a beta version of the Radeon Software Adrenalin 2020 Edition 20.5.1 driver. Supported models are Radeon 5600, 5700 and above.

NVIDIA Description: Can potentially improve performance and reduce latency by allowing the graphics card to manage its memory. AMD said it should improve GPU responsiveness and provide additional workload management innovations in the future.

You can check if you have this parameter or not. In principle, you can test it with yourself and unsubscribe. For example, I’m interested to know the results on AMD FX-8350 with a vidyuha GTX 1080. On top assemblies, everything is clear anyway (the number of frames per second is high) …

How to enable GPU scheduling

Under Settings> System> Display, select Graphics Settings . Here, enable Hardware Accelerated GPU Scheduling (slider from Off to On ). The Windows 10 variable refresh rate setting has been added to the same location .

Enable GPU scheduling with hardware acceleration

Expand the registry subkey HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Control \ GraphicsDrivers . Create a DWORD (32 bit) named HwSchMode  and value 2 . In fact, it is the same, you also need to restart your computer to use it.

How to enable GPU scheduling

You can check if GPU scheduling is working in the TechPowerUp GPU-Z app. For example, in the Advanced section, select WDDM (remember, the minimum requirements include the WDDM 2.7 version). And now at the bottom, see Hardware Accelerated GPU Scheduling – Off .

Conclusion

As real tests show, one can hope to get an increase. For example, the minimum FPS is up to 10%, and the average is up to 8%. It all depends on the specific hardware. Of course, top-end components do not require this functionality. There, and so everything is good at once.

In simpler terms, with the GPU scheduling function with hardware acceleration, the distribution work falls on the video card. This frees up important CPU resources and potentially reduces latency during rendering of complex scenes in Windows 10.
