Main solution is at the end! I know many have this issue, getting high CPU usage on their Vanguard / "User-mode interface" as shown in the Task Manager.
I had an extremely hard time finding any fixes online, aside from the usual (these have worked for some so give it a go!);
- Reinstall Vanguard - Uninstall it, launching the game will automatically prompt Riot Client to reinstall Vanguard for you
- Exclude Valorant and Vanguard from your firewall settings - Settings > Virus & Threat Protection > Manage Settings > Scroll down and under Exclusions click "Add or remove exclusions" > Add the file/folder for Valorant and Vanguard
- Set Valorant to high priority to lower lag/increase FPS - Task Manager > Details tab > right click on valorant-win64-shipping.exe > Priority > High
If the above solutions don't work, this definitely did the trick for me (it took me months to figure this out and I've had to cancel stream a few times due to the lag it'd cause)
- In Windows Search bar, type Services and open the tab
- Scroll down until you find "vgc"
- Right click > Properties > Set startup mode to "automatic"
- Click apply and OK
- In Windows Search bar, type "msconfig"
- Go to the services tab and check "Hide all microsoft services"
- Find vgc and make sure it is checked, press apply
- Restart!
Hope this works for you 💙
