Chrome is a memory hog since I always have apps open but it uses nothing else. With chrome on my memory is basically half gone, but with a game open like Farcry 4 or any other modern and intensive game, the memory goes up to 80-90% usage, and it starts stuttering, closing chrome and dropping the usage to 40-50% removes the stuttering. Why? does ram stop working after like 80%? Shouldnt I stutter at like 100% usage? or could this be another problem? all intensive games lag when i have chrome open. Should I get more ram?
