I fresh reinstalled Windows 11 a couple months back, and for a while now it seems like there's some sort of memory leak (?) that causes high CPU usage by the "System" process, high memory usage, and the occasional audible system stutter. Restarting fixes it for a time, but it eventually happens again.
Pics of task manager and resource monitor with my "usual set" of applications open. Vivaldi watching YT, Chrome open with work stuff, spotify, discord, obsidian, steam. I'm not entirely sure why VmmemWSL is there as I had just shut down wsl, but may not be relevant.
Process Explorer shows CcUnpinRepinnedBcb+0x370 as the primary CPU consumer for the system process.
This is my PC. TL;DR, Ryzen 9 7900x, 96GB DDR5-6400, NVME boot drive, 4070ti.
Some potentially related notes:
- I use WSL (v2) and docker desktop frequently; I set WSL's memory limit to 32GB. WSL's memory doesn't seem to free itself correctly (I'll end up with ~16-20GB used even after shutting down all containers/processes), but
wsl --shutdownsolves that. - I use Windows' multiple desktop feature and switch back and forth a lot
- The "System" CPU usage seems to significantly increase when there's something that actually should be using the CPU going on (eg: in a game, slicing a 3d model, rendering something), and does seem to affect performance.
- I have 4 monitors connected. One 2560x1440@144hz connected to the NVIDIA gpu, 2 1920x1080@75hz and 1 2560x1600@60hz connected to the Ryzen iGPU (all USB C)
- I have a lot of devices plugged in. Mic, headphone dac/amp, speakers, webcam, mouse, kb/m, controller, stream deck, etc. Every USB port on the back of my mobo is used, along with 2 from a USB 3 card.
- I also had an Elgato 4k60pro mk.2 installed, but removed it to see if it helped (it did not).
Any ideas, or other things I should check?
I've already run Win. defender and Malware bytes scans, and nothing came up.
I'm aware "free memory is wasted memory", however this seems like a bit much, and the CPU usage is also concerning.
