Windows 10: regedit: priority control (IRQ)

Can someone confirm setting priority control under KHLM\SYSTEM\CurrentControlSet\Control\PriorityControl for irq in regedit works ?
I read it is outdated residue from WindowsNT, but setting priority for cmos and than for gpu reduced input lag, so it seems it works.
There is also possibility set priority for devices/drivers in SYSTEM\CurrentControlSet\ENUM\pci etc. under affinity policy - by setting DevicePriority 3 for high e.g.
I talked to latencymon support and they told me affinity policy can be ingored on hardware level like chipset etc.
But nothing about priority control.
I wonder if there is actually benefit to setting priority for irq in windows, because i tested it and it seems to me input lag is lower, so i would say it works. I don't have 1000fps camera, but i am extremelly sensitive to input lag and can tell even 6 ms difference. I tested myself with inputlag ab test on blurbusters forums.

Change Wireless Network Connection Priority Order in Windows 10


Hello Denis,

The command in step 2 of Option Two should show your wireless networks listed in priority order. Top of the list is higher.

 

IRQ memory BSODS, device manager, memory range?

The only time I've seen that type of BSOD for myself is when I fried the PCI-e slots on my Striker 2 board... There wasn't anything that I could do, try and rma and go on.. I would suggest the steps that MilkyWay has said.. But, if you really don't know much about Bios's... I wouldn't play with Irq's... That can mess up everything on your board. USB, ethernet, ram, chip... But, that's just me on playing with irq's... To much of a hassle IMHO..

 

Windows (10) and Irq conflict

Maybe i didn't explain well.

I have seen one blue screen in the last year. the machine does not crash, it freezes. mouse won't move hd light doesn't flicker, frozen locked.

because of this there are no minidump files and no memory.dmp files

i did turn on a trap and I have some 1.4 MB crashdump files.

that is the file that shows me there are AMD drivers on my intel system (again, is that normal?)

if you want a couple of these files i will upload them.

If all devices in the device manager are enabled it will freeze within 5 minutes

if all devices that conflict irqs are disabled the system runs for hours.

what I leave enabled is

nividia video irq 16

HD audio irq 17

ehternet controller irq 18

sata achi controller irq 19

hd audio controller irq 22

usb host controller irq 23

if I load the primary usb controler or the wifi they go to irq 16 and the system freezes

if i load MSPro/xD controller it goes to irq 18 and they system freezes.
