A massive update has just been released for Mario Kart 8 Deluxe with version 4.0.0.

If you’re just skimming through, you might have expected Mario Kart World as the game getting the update. However, this is indeed for Mario Kart 8 Deluxe.

There’s a lot here if you’re a Nintendo Switch 2 player. Nintendo is offering higher resolution on the console, shorter loading times for racers, support for 5-8 players in multiplayer, and CameraPlay. There are a few other general adjustments as well.

The full rundown is as follows:

• Added support for the Nintendo Switch 2 display and high-resolution TVs, allowing for clearer visuals.
• Shortened the loading time before races and battles begin.
• Added support for 5–8 players in Multiplayer.
  • You can connect up to seven Nintendo Switch controllers (Joy-Con or Nintendo Switch Pro Controllers) to the Nintendo Switch 2 system. In order to play with eight people, you need at least one Joy-Con 2 controller or a Nintendo Switch 2 Pro Controller.
• Added CameraPlay support.
  • A USB camera (sold separately) is required to use CameraPlay.
  • Players can turn camera ON or OFF in Multiplayer (2-4 players) and Online Play modes.

  • When the camera is ON, the player’s face is displayed during the race.

• Increased player speed during races by the equivalent of one coin.
