Win10-11 'hardware-accelerated-gpu-scheduling'
It has given me about 20% to 30% more speed in some GPU heavy applications.

A script with HDR UHD video and tone mapping to BT709 now runs with 40 fps in AvsPmod:

video=LWLibavVideoSource(SourceFile, cache=True, prefer_hw=1)
audio=LWLibavAudioSource(SourceFile, cache=True)
audioDub(video, audio)
ConvertBits(16)
DGHDRToSDR(white=1420, black=0, gamma=0.42, hue=0.00, r=1.00, g=1.00, b=1.15, tm=0.90, roll=0.70, fulldepth=false, impl="255", mode="pq")
prefetch(4)

I haven't noticed any disadvantages yet.

It was already enabled on my system. (don't think I changed it manually)

Ok, by default it seems to be turned off in Windows, and I think most people (like me) don't know about it.

Must have enabled it when I installed my ARC GPU then.

Was also disabled on my Win10 machine. Interesting, never heard about this switch before.

Unfortunately, it's not a thing neither on my Windows 10 Enterprise x64 with an NVIDIA Quadro M5000 nor on my Windows 10 Professional x64 with an NVIDIA GTX 980Ti. :(

however it is there on Windows Server 2019 Standard x64 with an NVIDIA Quadro P4000.

Shall I turn on the flag on my production servers?
Well... after all why not, it's Monday...

Rebooting now.

EDIT: I made a .reg file that can be easily used to do the same thing and save time.




Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\GraphicsDrivers]
"HwSchMode"=dword:00000002

For anyone wondering, Hardware Accelerated GPU Scheduling for AMD Radeon is only supported by the 7000 series or newer.

Better idea: don't use Win10 or 11
