Vulkan api seemed to be giving me the frame stuttering in some scenes involving npcs, like the story train heist part, or the robbing the shop keeper scene in the benchmark, switched to dx12 and cleared it all up. Still crashing in some town areas, twice in valentine, and once when I rode into town for micahs quest, heard a lot of others crash in valentine as well, hope they fix that shit soon. Also bugged out on the horse quest in online, had to restart to get it working properly again, then got infinite load screen for online today. Meh..
