Crytek has announced native Linux support for its CryEngine. Linux support is another win for gamers wanting the industry to move its focus away from Windows. 
The new engine will also include the features that made Ryse: Son of Rome's creation possible, plus a new Physically Based Shading render pipeline. In Crytek's words, this means real-world physics simulation to create realistic lighting and materials.
Here's a screenshot of CryEngine 3.
