Hi,
I am facing 100% CPU usage when i play The Division 2. It causes FPS drop even in low resolution setting. Sometime it hang for 2-4 sec and sometime it become laggy.Previously i got around 70-80FPS at High resolution without any problem.    What can i do now? 
On the other hand I find my CPU fan vent which is located in the back side of my laptop is giving low airflow even in Max fan speed.
give me some idea what should i do?
