Like many I have major FPS drops by 30% (from 60 to 40). Really annoying and at times unplayable.
Already for a while I obeserved these stutters in OW. Maybe like a year or less. At least in Stadium it mostly happens during the perk phase and then suddenly vanishes.
Maybe Im wrong, but sometimes it feels like if I get too close to the spawn point the stutter happens again, also the enemy teams. But maybe Im totally off.
