The Crysis 2 DirectX 11 Ultra Upgrade

In this article, directly from the Crytek Principal R&D Graphics Engineer, Tiago Sousa, you can get more information on exactly how we went about re-creating Crysis 2 in DX11.  See below for a small quote from the article:

"With Crysis 2 being our first multi-platform game, our main focus was to ensure a successful delivery on all supported platforms. Unfortunately, such constraint didn’t allow us to concentrate on DirectX 11 with the level of commitment that is to be expected from a Crytek release.

This is the reason why it was decided to give the R&D team sufficient time and effort after the release of Crysis 2. The “DX11 Ultra Upgrade” is the result of this work: it is a free visual upgrade add-on introducing DirectX 11 support, as well as a wealth of graphical improvements and performance optimizations for both DX11 and DX9 API’s."

比较感兴趣的是基于粒子的dof

mooncocoon

那么多deferred rendering，关注一下有没有CS进来掺和

rickerlian

没有，只有nv吹得最厉害的tessellation
One of the most important updates provided by the DirectX 11 API is the introduction of programmable hardware tessellation, via Hull/Domain shaders. We decided to push harder in this area。。。。
从pdf截图来看，tessellation效果看不出来，除了那堵墙，而我觉得那里更应该是POM的范畴

他增强效果(POM，SSDO，DOF)改进显得更给力

Edison

POM 和 tessellation 相比性能消耗可能更大，而且存在损害画面品质（假设 step 不足够的话，看上去会怪怪的）的问题。

rickerlian

也是，明白

mooncocoon

确实没见CS，不过留了个话茬。
We believe that we only started to scrat**e surface of what is possible with the DirectX 11 API. In the near future, we will see a mu**er usage of hardware tessellation for visual effects and compute shader functionality for new approaches.

这算是刷存在感么……

RLR的加入倒是很值得关注，这玩意弄不好可以改变整个FPS竞技和游戏的玩法。其他的，我觉得应该说乏善可陈。即便是Sprite-based Bokeh Depth of Field给我的感觉也不好。

现在DOF有滥用的问题，总感觉要么摄像机位置的人是近视，要么就是在拍微距，看着挺难受的。
