High DPC Latency

[ScaVen]

Hello guys
BIOS Version: F.48
I have huge problem with high DPC latency on my Omen laptop
DPC Latency: https://pastebin.com/n2fRK7Dy

1. I reinstalled (the newest) Nvidia drivers (now without PhysX, only main driver)
2. I tried to disable Device Manager > Battery > something called battery control to solve ACPI.sys problem. And it worked, but my second monitor doesn't work 😕

3. I set Power Management Mode to Prefer Maximum Performance in Nvidia Control Panel and it helped lower DPC latency, but still it's too high. So maybe high DPC latency is connected with Nvidia drivers..

4. I installed Intel and Nvidia drivers from HP website so they are older than from manufacturer

Thank you for posting back. 

I appreciate your efforts to try and resolve the issue. I understand the difficulty with the problem.

Have you tried with external speakers or earphone or headset?

While you respond to that, I recommend you to perform the following steps to isolate the issue and arrive at a fix:

Firstly, let's run the Windows Update Troubleshooter: Click here 

Next, uninstall the Audio drivers, from the device manager:

To uninstall a device by using Device Manager, follow these steps:

• Start Control Panel, click Hardware and Sound, and then click Device Manager.
• Expand the node that represents the type of device that you want to uninstall, right-click the device entry, and click Uninstall.

Next: Install an updated audio driver

follow the steps below.

1. Confirm that the computer is connected to the internet.

2. Click Start, type device into the search field, and then select Device Manager from the list.

3. Grant permission to continue, if prompted.

4. Click the + (plus) sign next to Sound, video and game controllers in the Device Manager window.

5. Figure: Sound Device in Device Manager
   

1. Right-click the name of the audio device listed under Sound, video and game controllers, and then click Update Driver Software.

2. Click Search automatically for updated driver software, when prompted.

3. Windows checks for and installs any updated drivers. Restart the computer for the settings to take effect.

Hope this helps! Keep me posted for further assistance.
