Windows 10: DWM spikes in iGPU Usage (Dell)

For some reason, starting recently, DWM has been spiking my iGPU usage (up to over 80% worst case scenario) and thus bogging down the PC. In addition to very slow performance in games, this creates a wide array of issues like slower window animations. For some reason, this makes the GameDVR Service also spike in GPU usage (both werent like this before then). What should I do?

Recently I installed the KB4601382 preview on 10 20H2.

Intel UHD i5-1035G1.

Oh and I’ll add that I am using the OEM Intel gpu drivers (updated just last month to 27.20.100.8681), maybe that could be the issue

DWM acts normal when nothing is happening, it is window sizing and rendering a game that makes it spike in GPU Usage

- - - Updated - - -

I’ve been looking into trying to install the Intel drivers (instead of using the OEM drivers) and hoping it works from there, is it a good idea to do that?

Forgot to mention that I have the lappy hooked up to a 1080p monitor

Audiodg.exe Spikes Cpu Usage

Every 5 minutes or so audiodg.exe spikes my cpu usage to about 50% and any audio im playing cuts out and then comes back a second or 2 later. The video is completely fine and it's not a problem with
my USB Headset. audiodg.exe stays at low cpu usage when it's not spiking.

Solutions I've tried:

1. turning off audio enhancements
2. reinstalling lan, and audio drivers
3. turning off HPET
4. lowering the sound quality in control panel
5. DPC Latency checker (no change when spiking)

None of these solutions work. Please help.

 

Multi-Monitor and iGPU and dGPU usage/load

Hello, I have trouble getting my iGPU to do work when the dGPU is set as "main display".

I have an iGPU Intel HD4000 on my 3770k CPU, I also have a dGPU Nvidia GTX690 in a Multi-Monitor setup. Connected to my GTX690 are 3 monitors, and connected to my HD4000 is a 4th accessory display.

What happens is that when I play a video using VLC on the monitor connected to the iGPU, all content is actually rendered on the dGPU, then sent over the PCIe bus to the iGPU and displayed from there. I don't want my dGPU adapter to have anything to do with
VLC when the window is not on those monitors. I want only my iGPU adapter to do work when VLC is on that respective monitor. If I move the VLC window over to a different monitor which is powered by another display adapter, I want that adapter to take over
the work.

Example - Playing a video on the Monitor connected to iGPU:

1. When iGPU is set as Main Display then; iGPU 17% usage, dGPU1 0%, dGPU2 0%.

2. When dGPU is set as Main Display then; iGPU 18% usage,
dGPU1 8%, dGPU2 0%.

In the first case where the monitor connceted to the iGPU is set as main display, everything works as I want it, only the iGPU does work as it outputs the video to its monitor. But I don't want to have my iGPU as Main Display, I want the dGPU as Main.

In the second case where a monitor connceted to the GTX690 is set as the main display, dGPU1 is at 8% even though no monitor connceted to this Dispay adapter is displaying anything.... For some reason Windows10 lets the dGPU do all the work and pass the
result to the iGPU which then displays it. I want the iGPU to do all the work.

How can I assign a different Display Adapter to a program, other then the "Main Display" (which all programs default to, regardless of which monitor they actually appear on)???

Nvidia has something called "Nvidia Optimus" but is only available for mobile devices. But this is not available for desktop. Does Win10 have something like it where I can pick which GPU a program will use?

 

Explorer constantly spiking CPU usage for Win 10

Hi. Thank you for your answer. I tried all your suggestions, but nothing helped.

Clean bot seems helped at first but no after some hours spikes came back and now spiking more often with every hour of PC working.

Same happened also without clean boot.

Any other suggestions what to try ?

Just to let you know that I worked with Win 7 before with even more programs installed than now and I did not switched off my PC for weeks and CPU usage was lower in general not to talk about any spikes in CPU, newer noticed anything like that...

Thanks
