Ok! So many of you probably already know this, but I just realized and this to the newer players (why are you just started playing this game, I don't know, it's amazing). I tested the settings by running the fall of a cliff and die category. Now I am not the best, so I might have it wrong, but two of the same language (except English and English) is always faster. So by that I mean if you have an American Wii U set to English and the voice acting setting in-game to German, it's always slower. Besides, any voice-acting language with English text is slower. I also set the system language (the text) to French and then tried German voice acting and the results were [a lot faster than German and English], but slower than French and French which leads us to my original point. If you have German and French, sure the voice acting might be fast but the text will be delayed. If you have anything with English text, you are basically going to be experiencing the same speed as English and English (maybe slower).

TL;DR: Don't do two different languages as they are always slower. Stay with the same voice and text language for a better chance of success at running this game.

That's common knowledge already and the reason why nobody uses different languages. This has been tested immediately after the language switch was added.

Its simple: If you use Switch, use german. If you use WiiU, use German for PAL and french for NTSC.
