I used the steams own fps counter, i got a 144hz monitor and i use v-sync. Because the monitor does only have freesync. Anyways ive played monster hunter world, and when i log in and havent moved at all i tested the fps, and there was no difference. Btw i also have 16gb 3200mhz ram and i dont think thats the thing. And the fps in the game i get at the place where i log in is between 78-80.
