Thanks for suggestion, but I 've already did this.

Since I last updated the compatibility page, I've updated to unofficial bootcampdrivers.com version 18.12.3
Which works with Mario Kart.

Anything above 18.12.3 seems to not work with Netflix when playing 4K, using Edge or the Windows Netflix app.
If you don't care about watching Netflix in Edge/App, then you should be able to update beyond 18.12.3
