Halo 5 uses alot of CPU power when minimized

So halo 5 seems to still use a lot of CPU power when minimized, paused or on the main menu almost as much as when actually playing on a map.

this normally isn’t that big of a problem just annoying if I want to do other stuff on my PC but I started to work on a YouTube video and it’s annoying as hell I have to close the game if I want to research or look stuff up and halo takes about 2 minutes to load I only have a FX-4300 so I don’t have CPU power to spare with other games I just minimize it and they only take 0-5% of my CPU

I hope 343 fixes this
