Hi all, have an issue with the dwm.exe, where the system slows down so badly even if I have a couple of tabs open on my browser. however it isn't limited to that, some apps will also raise the dwm.exe up to 70-100% on the iGPU and slow everything else down because, being a budget laptop, the dedicated GPU (RTX 3050 Ti) has to run through the iGPU I believe.
Drivers are updated, Setting graphics priority is meaningless (more on that later), turned off Hardware accelerated GPU scheduling, can't switch it in bios, checked for any corruption, all dead ends.
Bios has also been updated.
Optimus, if it's using it, cannot be disabled.
Model: MSI Sword 15
Specs are 15-11400H, 16GB Ram, integrated UHD GPU, and a GTX 3050 Ti.
Now from what I understand i believe optimus is where the dedicated GPU has to go through the iGPU for some scheduling thing (Windows or the UHD determines which GPU is required dependent on power needed). Thus because the iGPU, when I'm doing anything worthwhile, is randomly crunching anything from 20-100%, it also by extension slows down the 3050 Ti.
Now i don't actually know if I actually have optimus, or if it is really the dwm.exe that's acting up, but I'd say I'm over 90% certain that the performance issue is somewhat related to the UHD graphics. I will find that occasionally that the games will run smooth, at good framerates, only for it then randomly get shot to ****, and this always aligns with the high DWM gpu usage on the UHD graphics when I tab to task manager (assuming Task manager is displaying GPU usage is correct). This is also what I mean when I say that directly setting app GPU priority is meaningless. I could set everything to the 3050 Ti, but if the app still has to go through the UHD first, and the DWM GPU usage shoots up, which it will, it'll slow everything back down anyway.
Who thought that'd be a good idea?
Anyone have any other potential solutions?
Out of curiosity why should DWM, which essentially just manages the windows UI, be so bad with GPU usage? The UHD may not be a dedicated gaming GPU, but it's a relatively "modern" one, and struggling with a UI that does nothing but fade out task bars and windows, it's like I'm paired with a archaic Riva TNT in my modern laptop i.e. very, very, old graphics chip for all the kids out there.
Thanks for any assistance.
