CPU utilization at 100% during COD Warzone
CPU utilization at 100% during COD Warzone
Your i5 creates a significant slowdown for the 1660 Super – it's not uncommon for quad-core i5s. They've been too weak for quite some time.
I notice the Battle.net app remains active during gameplay. It isn't a solution to your issue, but you should ensure it closes fully when launching games from it. When I used it with Destiny 2, I could run at low settings and barely hit 50fps (R3 2200g, rx480). Then I always closed it before starting a game, which let me play smoothly at medium/high settings around 60-100fps.
Your processor performs at the speed of a Ryzen 3 Zen+ or i3 9th generation, but lags behind a Ryzen 3 Zen 2 or i3 10th generation. Is it surprising that a 1660 Super, similar to a 1070, is limited by its bottlenecks?
You can stop the launcher without ending the game by pressing a key like Ctrl+C or using the appropriate shortcut in your system settings.
