The game is running perfeclty with Proton 9.0-1. I've completed the championship mode without issues.
Gane works fine except the intro video
Intro videos are not playing, but can be skipped with a click
Runs OOTB with GE-Proton7-48
Lowered TDP to 9-10
During gameplay, there are a few moments where the game dips below 60 FPS mainly when there is more than 4 racers on the screen and at random points during races.
At the start of the game after the Nickelodeon splash screen, the game is semi stuck on a black screen, to get past it, you need to repeatedly press the select button and the start button on the Deck until you hear audio in which then you press the start button and then the game works perfectly fine.
I didn't really need to change any of the graphic settings besides putting them on low to help conserve battery life as well as lower the TDP on the Deck, but other than that, expect 60 FPS gameplay with a few hiccups described above. DOn't know why the game has an unknown rating because it works very well.
