When you sell 72 million copies, you're going to get support well beyond the normal time, and so it goes with Mario Kart 8 Deluxe.

The Switch sales behemoth has received a version 4.0 update tonight, which is focused on performance for Switch 2 specifically with faster load times and the option for 8 player split-screen as well as camera support if in a GameChat session. At least one Switch 2 controller (Joy Con or Pro Controller) must be connected for 8 player local play, but the numbers can be made up with Switch Joy-Cons.

For those who haven't upgraded yet, the patch also provides a speed increase - the patch notes give an estimate of one coin equivalent - and owners of the Booster Course Pass can now select a "96 Race" vs option.
