Something something welcome to reviews! My friend is just getting into this game with us, but can only play this game on Mac. I don't know if there's currently a way to obtain a Mac build of this, so if there's a way that can be possible, that would really make these sessions better! Other than that, the uncapped FPS is awesome and the camera tilting, dear goodness the tilting!
There's no reason for you not to use this. Crashes are typically much less common than base game due to the large address aware flag making out of memory errors a thing of the past. Don't be scared off by the "Nightly" moniker.
