Game Stutters with 100fps and a 144hz monitor why? How do I fix

[Quinton465]

gpu- nvidia 1060
monitor https://www.amazon.com/gp/product/B074JLD4HZ/ref=oh_aui_detailpage_o01_s00?ie=UTF8&psc=1

Got the monitor today. it does have the display port in and I also made sure it was running at 144hz at the right resolution. I quickly figured out when i was running at 60hz at 100fps the screen tearing in pubg was pretty bad so I changed the monitor settings to what it should be. When I played after fixing the issue i was getting bad stutters like those micro stutters but the fps remained around 100 so there wasnt any noticeable frame drops.
Im not using v-sync or any other sync.
Questions
1. does playing at a lower fps then the refresh rate on a monitor affect gaming negatively.
2. if it does how do you fix it
3. does triple buffering cause micro stutters. (i wasnt using tripe buffering while in pubg games)
