High DPC (ACPI.sys) when Load Kernel Driver is Selected

Hi,

I noticed I get High DPC usage when using my sensor panel. I noticed that by disabling Load kernel driver in the stability section in Preferences, the latency issue disappears. 

Unfortunately this disables monitoring of most of the things I want in the sensorpanel. 

DPC goes from <650 microseconds (on nvlddmkm.sys - Nvidia) with the setting disabled to ~1800 microseconds (on ACPI.sys) when I have load kernel driver selected.

Is there something I can enable/disable in bios to stop this from happening?

CPU: 10900k

MOBO: ASUS Hero XII WiFi bios: 2301

RAM: Corsair 16-18-18-36 32 GB 3200 MHz

GPU: ASUS 3080 Strix OC

Windows: 21H1 19043.1165

I do not have ASUS software installed besides audio drivers and I only have fan profile in BIOS + overclock.

I also have NZXT cam installed and Geforce experience.

I have solved the high latency issues by disabling EC support in preferences -> stability

However, now I cannot get CPU power, VRM temp or CPU opt fan speed on the sensorpanel

So I wouldn't call this a solution because some others don't have a similar issue with EC support enabled.

      I've been trying to find a reason of why my new pc got issues with latency and one of the culprit drivers was ACPI.sys
       
      Apparently whenever AIDA64 started worked ACPI.sys would have the second highest DPC/ISR timings as well as execution time over 1ms
       
      Switching off kernel driver in settings fixed the issue after restarting AIDA but unfortunately it would also make me lose GPU temps and loads.
       
      I've been wondering whether this is a normal behavior or whether it can be somehow avoided?
       
      Also i've been wondering whether AIDA64 uses driver called wdf01000.sys which is causing delays over 500ms as well as huge lag spikes and sound stuttering when used in combination with LCDHost and G19s keyboard?

      Hi,
       
      I just seen some untranslated and currently untranslatable strings on the dialogs to send on-demand reports to FinalWire. These strings are "Report submited successfully", "Detecting ACPI tables" and, one that I aren't sure if actually exists, a question the program may ask when runing for the first time: Do you want to generate a report of your computer and send it to FinalWire?
       
      Thanks!
