when i play gta v on 1080p and ultra settings,msi afterburner monitors 50% cpu usage and 99-100% gpu usage but when i play csgo,game uses 40-60% of the cpu JUST ON THE MAIN MENU and +80% ingame,causing the card to use less than 40% of its full power,is this normal?most people on youtube got more frames and gpu usage with a 6400...
