Run normally, all Chrome processes have normal priority. The various threads represent various tabs, extensions, etc.

enter image description here

But, then i launch chrome with high CPU priority. I'm using:

cmd.exe /c start "" /high "C:\Program Files (x86)\Google\Chrome\Application\chrome.exe"

Then a few threads run with high priority, some Normal, and others run Low priority.

Is it possible to make all chrome sub-threads run with High priority?

Maybe i could achieve it by running chrome in single-process mode, but that's non-ideal.

This is a partial solution. By my testing, it appears to prevent any chrome process going to "low" priority, although it doesn't prevent "Normal" priority.

Use the --disable-renderer-backgrounding chrome startup switch. https://peter.sh/experiments/chromium-command-line-switches/#disable-renderer-backgrounding

start "" /High "chrome.exe" --disable-renderer-backgrounding

i noticed immediate improvement in Chrome performance with this switch. I believe it allows inactive tabs to load with normal priority, instead of getting low priority. I have not noticed any negative impact on the active tab.

I want instead to set all threads to Low Priority, not to high priority which the thread starter wants, so that their CPU-usage doesn't interfere with my game and make my gameplay microstutter and cause input delay from keyboard. I for example listen to a youtube video or have something going on in the background while playing a game and want only my game to have high priority usage of the CPU.

How can I select all instances of google chrome.exe or steam.exe (with its around 10 instances of steamhelper.exe) or other threads and set them with one mouse click to low priority? After that I will set only my game to high or realtime cpu usage.

Only some of the subthreads are set to low priority when doing it in Process Explorer, I wonder why not all are set to low?
