It probably comes down to cash and time. I'm pretty sure I've read an article that talks about this very thing, and when it comes down to it, there likely are devs working on menus and control ui until the very last minute, but the ones in charge of money don't want to spend that money on the time required to implement/QA those changes instead of saving money and shipping as is.Fair warning, I think we agree. It's just that it really is not rocket science. This is really, really basic engineering and ergonomics. The answers are out there on the PCGamingWiki, I can't possibly believe knowing what an option menu ought to contain is an unknown to the gaming industry, not today.
If this is rocket science to them, it is because of incompetence or lack of willingness to care. Not because it is hard. Making a game is hard, not this.
I'm guessing this is what you meant but I still balk at the idea of acknowledging or rewarding the gaming industry for deigning make a proper port for PC games. They don't deserve recognition for doing a good enough job. Sales and user reviews are enough.
When it comes down to it, UI changes < other bugs/features
