Nitro-Fueled has a steady frame rate of 30 frames per second on the original PlayStation 4 hardware, but those of you with an Xbox One X and/or PlayStation 4 Pro will be able to enjoy the game at a solid 60 frames per second when all is said and done. These will no doubt be the superior versions of Nitro-Fueled, though there's nothing wrong with taking the game on the portable front with the Switch, if you can step away from Mario Kart 8 long enough.
Super disappointing for the base version, but at least the people with a Pro or an X will be able to play it decently. It doesn't sound too good for the Switch though.
