Higher texture resolution and more AA options.
Otherwise is the same game with 4 or 5 predefinied keyboard layouts and the same 900p ingame videos...
It's just a money grab.
I'm not sure what you think developers should do to cater to the PC better? Certainly you won't get extra content or major gameplay changes.
For the entire history of cross-development, PC titles were lucky IF they received high resolution textures (ultra) and more AA options.
If they did pre-rendered videos, scaling them up would make for an even bigger download, more QQ.
As a PC gamer foremost, better textures, resolution & AA are what I want to see available for the PC version. If it has that, it clearly shows the developers cared. To think some loyal NV user would go out of their way to throw dirt on these devs .. "it's a money grab"? LOL WTF are you expecting for your PC master race?
As for the graphics itself, you cannot claim its unoptimized when its running at great performance with SSAA AND giving superb overall IQ. You could say its unoptimized for NV hardware and hope for a driver fix.
