In game v-sync is the one that causes the biggest issues for stuttering "FOR ME" , my work around is to turn it off in game and use the fast version in NV control panel , Im always using track ir with clouds on , in game settings set to high and doing a lot of 100mps 4k recordings at the same time , I would say that this gives me 98% stutter free where as before the game was almost unplayable on my mid range pc.
