I have the issue in PvP as well. It started last night out of the blue. Smooth as butter in orbit, but once I drop into a pvp game it stutters to no end. GTX 1070, i7 6700K, 32gb ram. Haven’t changed anything from the last time I played except going from 16 to 32 ram. Either something in the weekly reset or for some odd reason the ram upgrade did it, which wouldn’t make sense. Going to give the steam friends fix a try later today, I really hope it works. It’s a dumb fix but the stuttering is near unplayable.
