Windows 10: Hardware-accelerated GPU Scheduling affecting Task Manager

There is a 2022 post in the Windows 10 forum complaining about the effect of Hardware-accelerated GPU Scheduling HAGS on Task Manager. Viz., the number of "engines" shown on the GPU section of the Performance tab drops quite a bit. Because the CUDA engine disappears from Task Manager though CUDA tasks will still run, users can no longer monitor CUDA work being done by the card. Also, depending on how games use the DX12 APIs, graphics activity, as reported by the "3D" engine, sometimes comes in suspiciously low. Task Manager can no longer see all the work that is being done by the card.

Hardware-accelerated GPU scheduling causing BSOD

Hi, I seem to be getting BSOD when using Hardware-accelerated GPU scheduling = ON.

My configuration is:

• OS: Windows 10 2004 (build 19041.388)
• Motherboard: Asrock z77 extreme4 motherboard with Intel HD graphics 4000
• GPU: Gigabyte GeForce GTX 1080

Windows features enabled:

• Virtual machine platform
• windows hypervisor platform
• windows sandbox
• windows subsystem for linux

I have one monitor (monitor1) connected to the GTX 1080 card, and the other (monitor2) to my integrated graphics on my motherboard. I have WSL2 and Docker running fine on my PC, so interoperability with Hyper-V is working well.

I have noticed that when I set Hardware-accelerated GPU scheduling = ON, my PC has a BDOD whenever I place specific applications (like Remote Desktop Connection) within monitor2 which is using Intel HD graphics 4000. I also noticed I get a lot of HAXM errors in my event viewer e.g. HAXM can't work on system without VT support . I'm guessing my problems are a result of HAXM not being compatible with Hyper-V, so that when Hardware-accelerated GPU scheduling = ON, it is trying to use HAXM for GPU acceleration on monitor2 (using Intel HD graphics 4000), which then results in a BSOD? The BSOD error reports a problem with dxgmms1.sys.

I have ordered some DisplayPort cables so that both monitors will run from the GPU, and will disable integrated graphics to avoid problems like this in the future.

Thanks for any insight.

 

Why I dont have Hardware Accelerated GPU Scheduling

Hello Williamna1,

Hardware-accelerated GPU scheduling requires a GPU that support hardware acceleration, combined with a graphics driver that supports WDDM 2.7 or higher.

OBS stream crash when Hardware-Accelerated GPU Scheduling is enabled

Stream abruptly stops (bitrate is 0 kb/s) and OBS crashes (Hardware-Accelerated GPU Scheduling is enabled)
i created ticket with OBS but according to them its a GPU vendor/ Microsoft issue Stream abruptly stops (bitrate is 0 kb/s) and OBS crashes (Hardware-Accelerated GPU Scheduling is enabled) · Issue #8746 · obsproject/obs-studio
since I'm using a 40xx gpu , and Hardware-Accelerated GPU Scheduling (HAGS) is required for DLSS3 frame generation.
