Hi. I'm very new to pc gaming. I've had my pc just 3 months and I've been playing call of duty perfectly fine up until a few days ago. My cpu usage in task manager is between 80% & 100%. In game I'm getting latency I wasn't before. The in game cpu time is resting at 17ms on the menu screen (lobby) but goes higher in game. My gpu seems normal on the in game display. I've tried reinstalling graphics card & all driver's. A full system reboot. I've followed every suggested tutorial online either YouTube or web pages and nothing has worked. I'm new to all this and wonder if I'm missing something. This happened suddenly after 3 months of amazing performance so I really dont get it. Please help.
