High CPU usage causing stutter

Here is my system: an i5 9400f and a 1660ti Overwatch is installed on a new gen 4 NVME Western Digital drive. But I cannot play this game without stutters? I understand games become more and more demanding as time progresses but this is absurd in time that OW2 launched in Oct 2022 to now it has been 4 years and the MINIMUM requirements went from an Intel Core i3 or AMD Phenom X3 8650 to an apparent i5 9400f 1660ti, to put this in perspective this increase is the same from MINIMUM system requirements to a Recommended system requirement, and this is for me absurd because the game will not even maintain 60 fps on all low for this system. Please start optimising this game, it is unfortunate to see the 10 year old game cannot keep up with hardware that is actually newer than the game itself and that other games which were heavily criticised for their performance are now seeming to be on part with this game and it’s not for them catching up and maintaining their game but for Overwatch’s standards slipping.
