I had micro stutters which I just accepted as people say pubg is bad. Found this on google about adjusting virtual page file (fix stuttering section) and seems so much better since then:

Agreed you shouldnt have to be tweaking things to get decent performance. Unless you experience the stutters you won’t understand how annoying. Some folks seem to have no issues off the bat.
My only real annoyance is the delay on loot appearing. So frustrating to land first but room is empty only to run back in a couple of secs later and its all there.
