You say your Titan X is running it good, well, that's fine for you, but, if you followed the steam thread on the game, people with Titan X's were complaining about performance as well.
Your 10.5GB number was got from before all the performances fixes. Fixes like reducing MSAA from 8x, as it made no visible difference.
The quality of the game IS the point. There is no way that this game should be using 10.5GB of Vram, there is nothing about it that looks better. IT was broken right from the start.
If this is an example of the games on the horizon, then it's a pretty bleak future ahead, no improvement in graphics with more memory use. And it's very relevant, I would hope that there is an increase in graphics quality for that amount of Ram use in future games.
