I have been playing on the PS4, and one of my biggest quips would be the sprint button. It's being treated like a PC sprint button rather than a console sprint button, you have to hold L3 to continuously sprint, where most games "toggle" sprint until you stop moving. I'm not sure if this is something that is easily fixed, but it definitely has put stress on my left thumb when playing for a while compared to other fps games on the PS4.
Loving the game, been waiting since I heard it was coming out for the PC. Thanks for all your hard work bringing this gem to PS4.
