Do different versions of Deus Ex: Human Revolution differ visually or mechanically? How so?
Solution 1:
As described in that article on Ars Technica, the PC version has a few graphical enhancements:
- Use of DirectX 11-specific functionality.
- Support for AMD's HD3D and EyeInfinity technologies
- Higher resolution options (well, obviously)
The user interface is also reported to have been optimised for use with a keyboard, and mouse controls can be customised to fit your preferences.
I do not know whether the XBox 360 and PS3 versions differ in any significant way in either graphics or UI.
