In the Windows 10 May 2020 (20H1/Version 2004) feature update, Microsoft introduced The Windows Display Model (WDDM 2.7) improvement to add hardware-accelerated scheduling (HAGS) to the GPU. In a recently updated official support document, Microsoft released more details about the feature.
Hardware-accelerated GPU scheduling is the primary feature of WDDM 2.7, allowing integrated/discrete graphics cards to manage your memory directly, allowing you to achieve better performance, reduce latency, improve average or minimum frame rates, and improve video playback.
With hardware-accelerated GPU scheduling, Windows 10 can now hand control of memory management to a dedicated GPU-based scheduling processor, which in theory should free up the CPU and reduce input lag.
This feature is not obvious on high-end CPUs because they are fully capable of GPU frame processing. “User input is received by the CPU during the ‘N1 frame’ but is not rendered by the GPU until the next frame,” Microsoft said.
However, hardware-accelerated GPU scheduling can prove useful when playing on low-end and mid-range CPUs. According to Microsoft, hardware-accelerated GPU scheduling should also reduce gpu scheduling overhead and modernize a fundamental pillar of the graphics subsystem to “prepare for things of the future.”
For now, however, users may not see any significant improvements when the feature is enabled.
How to enable it
1. Download the Windows 10 May 2020 (20H1/Version 2004) feature update or Build 19041 and later, search for “Winver” in Windows Search, confirm the version
2. Download Nvidia GeForce 451.48 or Adrenalin 2020 20.5.1 Beta driver. Ter eis ire is planning to update their WDDM 2.7 driver in the near future to support hardware-accelerated GPU.
After upgrading to Windows 10 2004 and compatible drivers, go to System, Show, Graphics Settings, and enable the Hardware Acceleration GPU Scheduling option, and restart your PC.
“WDDM 2.7 introduces a new feature called hardware-accelerated GPU scheduling,” Intel said. Current Intel DCH drivers do not support this feature, but Intel hopes to include support for this feature in future driver releases. “
A few days ago, AMD quietly released the 20.5.1 Beta GHS driver, where GHS is on behalf of “Graphics Hardware Scheduling” (graphic hardware scheduling).
AMD graphics cards are finally starting to truly support Windows 10 v2004’s hardware-accelerated GPU scheduling, which can be turned on at the graphics settings set by Windows system settings. AMD graphics cards are currently limited to the latest RX 5700/5600 series of high-end cards, even if the RX 5500 series has not yet been added, let alone the older RX Vega and RX 500/400 series.
