Desktop Window Manager high GPU OBS
|
For some reason, when I load up OBS studio to get ready for a recording or stream, I see in Task Manager that I have OBS and Desktop Window Manager taking up around 30% of my GPU (combined). This is just running OBS and nothing else.However, when I load up certain games, like Halo infinite, Forza, or any other graphically decent games and press on the streaming or recording button in OBS, my DWM and OBS shoot up to around 40% usage EACH, leaving only little room in my GPU for the game or other programs I need to run. I don't have too much going on at all in the scenes I am trying to run, I jus

Since you have not mentioned the make and manufacturer of the monitor.. I am answering this on an assumption that if you do have HDR enabled then try turning it off inside the windows color portion of the Display Settings and then see and report if the usage goes down or not

All my specs I could find are now updated to their manufacturer name so there is no more guessing. I do not have HDR.

Had you tried updating the game "Gears"?

Try this only. Open Nvidia Control Panel - manage 3d settings - program settings - look for DWM.exe and change power management mode to Optimal power.

It didn't work. I wouldn't mind this issue if it didn't degrade my performance. DWM's GPU usage is fluctuating between 15-50% constantly. It's not a steady usage. On top of all this, if I try to type in a browser/Discord I can see the letters lagging as I type as if my PC is at 100% usage. I was thinking maybe Windows is bugging with Gears 5 and is showing DWM using my GPU when it's in fact Gears 5, but that doesn't explain the fluctuation nor the performance degrade.

I have, yes. I don't think it's Gears 5, though, as I'm active on their forums and I don't see anyone talking about this particular issue. EDIT: This is what I see within Task Manager:

Did you try to DDU and re-install the Nvidia Drivers again?
Local time 7:40 AM Posts 12 OS Windows 11.
I have not, no. I assumed it wouldn't work as all the other threads I have found online with my exact issue have tried that suggestion and it hasn't worked. When I installed Windows 11 over a week ago, it had no NVIDIA driver. I had a complete fresh install when I installed the latest driver. EDIT: It's now at near 100% utilization, and my PC is gasping for air, lagging at nearly everything I do. This is an example of what happens with DWM; it shows all other programs utilizing my GPU using much more than they normally do. OBS was using 11% in my last image, now it's using 37%.

Do you have pcie riser cable plug to your GPU?

Your problem is related to hardware because it still occus in win10 and win11. Try this first. Update BIOS and dont use snappy driver to update drivers. Install drivers from manufacture website

I don't have one of those for my PC. I don't know if deleting/installing all my drivers would help as others have had this issue with different devices/drivers. I mainly don't want to manually find/download all my drivers.

GPU drivers from Nvidia rest from Asrock. As I have OBS Studio and a GTX1080TI have had a look, you clearly have a problem.

Click on Event Viewer (Local) and wait for it to fetch all the logs. then you will see Summary of Administrative Events appear in middle pane. Under that heading are two branches labelled "Error" and "Warning". Click on those to expand and view logs.

Thank you! This is what you wanted, correct?
