(enough for highest quality at 4K) yes the game seems to have s* optimisation.
RT = Ray tracing PT = Path Tracing FG = Frame Generation

Since that gpu has 24 GB of vram the game might be using more than it really needs, just because it can. The best way to test the importance of vram would be to get two cards of the same tier with different vram amounts (like the A770 8GB and 16GB) and see how that impacts performance.
There are also plenty of totally reasonable settings that require less than 12GB, 1440p maximum settings for example. If you want the best of the best, obviously you have to pay for the best of the best.
(It’s still a lot and a minimum of 12GB is already ridiculous. I’m just saying the claim of 16GB being not enough is kinda dishonest)
Hasn’t this been an argument by PC gamers against consoles, that games aren’t deliberately held back by old hardware?
I think it was mainly about games releasing with 30 or 60 fps hard caps back in the day than graphics being held back.
