There's an interview with Eidos: Montreal and Nixxes Software on GameSpy discussing the Windows edition of Deus Ex: Human Revolution, the upcoming action/RPG prequel. This covers the efforts made by Nixxes Software and AMD to create a version of the game that is more that just a straight port of the console editions. Here are a pair of quotes about this:

Julien Bouvrais: First off, Nixxes developed a DX11 renderer that is used on the PC, when available. We did leverage this by adding several features you will see when you have DX11 hardware on your PC: real-time tessellation, improved Screen Space Ambient Occlusion, improved blurs and depth of field. We also added custom support for AMD's Eyefinity (multiple monitors), and 3DHD. On another note, the user interface has been tailored for the keyboard, and mouse controls can be fully customized for your gaming habits.

Jurjen Katsman: We did quite a lot of work on anti-aliasing as well. We offer various anti-aliasing options to gamers to choose from depending on how powerful their hardware is. They really help smooth out rough edges that you can see more easily on a PC monitor.
