It struggle tu run on every hardware so i have fear to see how it run on switch tbh.
They should focus on optimization before thinking to expand on other platforms.
It'll be golden on the Switch. It'll run perfectly just on the Switch and PC. The XboneX and PS4 versions will forever run like ass but the Switch version will run perfectly. Not only that but when tech geeks and outside devs tries to investigate on how is it possible that PUBG runs so well on the Switch but runs poorly on the other console the only serious answer they will be able to give is "I have no idea how or why this is the way it is so we should all just accept it."
