One conclusion is that Unity's technology stack is more like a Tower of Jenga with pieces in random state of readiness and compatibility. More and more Unity comes out looking like a mismanaged mess that lost its way from the goal of "democratizing game development".

I'm guessing the studio was pressured to release on a hard deadline to make the publisher their promised profits. This game would have been a guaranteed first day purchase for me, but the bad press coverage now made me move on to other games in the limited time I have. So I may check back to see if the updates fixed the pefromance in 6mo or never. What I'm saying is that the person who decided on this release date likely made a long term strategic mistake for short term profit, or was forced to do so by another idiot up the chain.
