Multiplataforma Sea of Thieves tendrá un modo opcional a 540p y se podrá bloquear a 15fps (EN PC)

We've actually added a 540p mode, so you can go below HD. We've also added a 15 fps framerate lock because when we were talking to the community some people were like: I'm actually happy playing 15 frames per second. We were like: that's actually really cool, we should support that. And to them go to them and say, oh, we've added that mode for you—it's below our Rare certified min spec, but if you're enjoying the game, why should we as developers knock you for that?"

Por eso lo hicieron así con el Lagman Arkhan Knight en PC?
