I have my laptop for 4 months and lately I have installed black ops 3 and after 1 day of playing it, it started to lag even in offline, I don't know what to do to avoid this to happen or if the game is too much for my laptop, my laptop uses an Intel core i7, 8gb of ram, 1tb and a Nvidia GeForce 940 m. Please some one tell me what to do so it doesn't lag.
