cinnamon 5.0.5 high cpu utilization
I'd upgraded my desktop to Linux mint 20.2 and faced with an issue: the cinnamon process uses a lot of CPU. On idle it uses about 20% of all of my 8 cores, when I'm moving windows or scrolling them the cpu utilization increases up to 300-400%.

Re: cinnamon 5.0.5 high cpu utilization
I update my kernel to 5.4.0-80-generic and it looks like the problem was solved.
Today I did decrease the cinnamon nice to the lowest value (+20) and watched that it spend a lot of time in some system calls.

Re: cinnamon 5.0.5 high cpu utilization
I think this means that your video acceleration doesn't work. Cinnamon using software rendering would explain high CPU usage.
Re: cinnamon 5.0.5 high cpu utilization
What you highlighted indicates the Intel driver is installed and running properly. The i915 driver uses the modesetting driver.
Cinnamon is using Intel hardware rendering as indicated by the below:
Graphics:
Device-1: Intel UHD Graphics 630 vendor: Micro-Star MSI driver: i915 v: kernel bus ID: 00:02.0
Display: x11 server: X.Org 1.20.9 driver: modesetting unloaded: fbdev,vesa resolution: 2560x1440~60Hz
OpenGL: renderer: Mesa Intel UHD Graphics 630 (CFL GT2) v: 4.6 Mesa 20.2.6 direct render: Yes
With a 9th-gen Intel cpu, the OP would probably see better performance running the 5.8 or 5.11 kernel. Both of those are available in Update Manager.
Open Update Manager. Select View > Linux Kernels and click Continue. Make sure 5.11 is selected on the left panel and then click the top-most option on the right panel. An "Install" button will appear. Install the kernel and then reboot for it to become active.

Re: cinnamon 5.0.5 high cpu utilization
The OP has Intel graphics and not AMD graphics. Modesetting is the preferred display driver for Intel graphics and the display driver is separate from the renderer.
If there was not hardware acceleration then the OP would be getting a pop-up message saying there is no hardware acceleration. That is not the case.
I have already pointed out to you that there is hardware rendering. Software rendering would indicate
renderer: llvmpipe
, but the OP has renderer: Mesa Intel UHD Graphics 630

Re: cinnamon 5.0.5 high cpu utilization
On my only Intel machine, I do get the "intel" driver for X11, and "modesetting" unloaded.
Good point, yeah.If there was not hardware acceleration then the OP would be getting a pop-up message saying there is no hardware acceleration. That is not the case.
Re: cinnamon 5.0.5 high cpu utilization
There are some much older Intel graphics for which intel is the display driver, but modesetting is the newer, more up-to-date driver. I do not recall seeing modesetting unloaded on the cases where the intel display driver is the preferred one, but those cases are few and far between so I could be remembering it incorrectly. I have a second-gen Intel cpu and its graphics are driven by modesetting, so when I say older, I mean older.

Re: cinnamon 5.0.5 high cpu utilization
1. logout of your session
2. change desktop environment to Cinnamon(default). if you don't know how to change desktop environment, look at the top right of password form. there is a circle with two mountain drawn. click there and you will be asked to select desktop environment.
3. log back in
this is how i solved my issue.
let me know what happens.
