Plutonium

Bro its a bug. This is first time. My Core 2 Duo can run it at 80 fps but happens in laptop. I play RE8, Sekiro, Black Ops 3 etc and those games are fine.

In Zombies, In the Main Menu The Game Is Fine. Constant 60 FPS But When Start A Map It Is Lowered To 22 Fps and Hardly Goes Above 30 FPS. My FPS Rate Is Fine In Multiplayer. Constant 60 FPS But Not In Zombies. It Happened Today. Anyone Has Any Ideas?

Can Somebody Please Help Me With This? Im Having Serious HeadAches.
