I'm guessing he's using task manager and because he has a decent system it's no where near 100% if it is that is a bad thing, it's throttling and reducing clock speeds. For Bf5 and big map games it will be higher cpu usage. Games like tomb raider are gpu heavy. And he's prob playing games that aren't dependant on spending big. Which is what is needed to match a 144hz monitor nowadays(might scrape with an oc) but for that u need a k chip.What games, solitaire or BFV? What are you using to monitor the usage?
