Hardware-accelerated GPU Scheduling: Besseres VRAM-Management unter Windows 10

One of the new features of Windows 10 v2004 is hardware accelerated GPU scheduling, which is now supported by AMD and Nvidia. There is one for Radeon graphics cards Radeon Software 20.5.1 Beta, for Geforce models Geforce 451.48 as a suitable driver. To switch on hardware-accelerated GPU planning, you have to navigate to the graphics settings of Windows 10 under System and Display.

Hardware-accelerated GPU Scheduling (HAGS) was introduced with Microsoft’s WDDM 2.7 and the May 2020 update for Windows 10. According to AMD and Nvidia, the video memory is now managed directly by the GPU in hardware, previously the operating system had a major impact here. This is quite interesting because, for example, with the change from Direc3D 9 to Direct3D 10, the graphics driver was given less and less decision-making power.

The hardware-accelerated GPU planning should optimize the management of the video memory. Primarily, this is about shorter latencies, which according to Nvidia can lead to improved performance. AMD, in turn, vaguely adds that HAGS will allow further innovations in GPU workload management in the future. The function runs at Nvidia on all Turing models, at AMD so far only on cards with Navi-10 chip (Radeon RX 5700/5600).

A first short PCGH test According to hardware-accelerated GPU scheduling, the frame rate increases minimally. Most benchmark results with a Geforce RTX 2080 Ti are on the verge of measurement inaccuracy. In return, there were several crashes, which apparently are due to the overclocking of the RAM of the Ryzen 9 3900X used. It runs with DDR4-3600 outside the CPU specification and also with very tight timings.
