Windows 10 May 2020 (20H1/Version 2004) introduces a number of game improvements that include support for WDDM 2.7, but unfortunately it does not include the option to enable hardware-accelerated GPU scheduling. Hardware-accelerated GPU scheduling is a key feature of WDDM 2.7, allowing integrated/discrete graphics to manage your own memory directly, allowing you to achieve better performance, reduce latency, increase average or minimum frame rates, and improve video playback.
Support for WDDM 2.7 is included in the latest drivers released by Intel and NVIDIA, but the problem is that there is no hardware-accelerated GPU scheduling option in Windows settings.
NVIDIA says it has support in Windows 10 May 2020, but the latest Game Ready 446.14 WHQL driver is not based on WDDM 2.7, which is why there is no hardware to speed up GPU scheduling.
Intel, on the other hand, has not provided any communication on hardware-accelerated GPU scheduling, and AMD and NVIDIA have confirmed that they will support future releases.
