本软件是由crytek机构出品的CryEngine EaaS游戏引擎软件V3.8.1.13版，CryEngine 3.8.1.Build 13，大小：5.4 GB，支持Win系统，语言：英语。
CryEngine引擎将会进行一次新的技术升级，改进后的EaaS引擎将会针对普通人群进行低价出售使用，每月只需要9.9美元，极为低廉。以CryEngine引擎为原型开发的面向传统大众的新引擎"Engine-as-a-Service" (EaaS) 技术，这使得这一用于专业领域的技术能够大众化使用。CryEngine引擎拥有十分强大的性能，xbox one平台早期发售的画面精美的动作游戏《崛起罗马之子》就是采用这一引擎制作，使用这一引擎用来游戏开发也将更加方便。
Crytek正式发布了CryENGINE 2的升级版CryEngine 3，目前Crysis2《孤岛危机2》采用了该引擎。最新的CryEngine 3引擎为3版。CryEngine 3引擎是世界上最先进的和大量授权的应用引擎，该引擎不单只是授权给游戏工作室开发游戏，还大量授权给了学校，建筑公司，医院和一些视觉公司和个人使用等，个人使用者可以登录专门的网站注册，然后签署并提交保密协议，就可以获得相应的软件授权拷贝。
最新CryEngine 3引擎将会加入更多的图形功能，更强大的物理破坏效果，动画技术以及多个游戏技术的增强功能，例如大范围开放的环境、建筑内部丰富的细节、高级任务表情以及动作、新的改进版SandBOX编辑器、多种不同平台实时所见即所玩的开发、引擎内色彩等级、程序破坏与物理效果等高级先进技术。CryEngine 3引擎在PC平台上也支持DirectX 9、10、11，并且支持多核心技术来获得对称多处理和超线程，同时也支持32位和64位的版本。
作为声名显赫的CryENGINE引擎的第三代，CryENGINE 3继承了前辈在画质方面的突出造诣，而且这次不仅限于PC平台，还可用于PS3和X360等主机平台，这也是Crytek首次进军游戏机领域
CryEngine 3.8.1.Build 13
Welcome to CRYENGINE 3.8.1 (out now for all subscribers on Steam), the most feature-packed release since we launched the Engine-as-a-Service model in May of last year!
CRYENGINE 3.8.1 is now available
New API: OpenGL Support
Starting with 3.8.1, we are shipping a fully-featured OpenGL rendering implementation with CRYENGINE, which goes hand in hand with Linux support for your games (see below).
New platform: Oculus Rift Support
You asked about it, and we listened: Just in time for the announcement of Crytek’S new VR title “Robinson: The Journey” at this week’s E3, we are putting support for the Oculus Rift HMD (Head-mounted display) into EaaS users’ hands. We’ve included a small demonstration level, aptly titled the “VR_Demo” level. This showcases some information on how you can approach setting up your levels for VR, some of the implications and the immersive benefits of using VR.
New platform: Linux
As previously announced, we are adding Linux support for your Game.exe. While you will still need Windows to use the Sandbox Editor, you can now release your commercial games on Linux as well as on PC- and of course, there are still no royalties whatsoever!
New feature: Voxel-based Volumetric Fog
With today’s release, we introduce an all new voxel-based volumetric fog system. The system supports illumination from deferred lights, respects clip volume boundaries and works consistently with transparent objects including particles.
New feature: 8-weight GPU Vertex Skinning
Skinning of complex animated meshes that use more than 4 vertex weights (up to 8 weights) can now be performed directly on the GPU which can significantly reduce the CPU load.
Improved: POM Self-Shadowing
This is another topic we had a lot of feedback on from our users on the forums, so we are happy to report that POM self-shadowing is back and working efficiently with deferred shading, allowing the sun to cast shadows from the heightmap used for POM (Parallax Occlusion Mapping).
GameZero
The GameSDK project is a full blown game example. It demonstrates how most of the CRYENGINE features can be utilized, but its size and complexity can be overwhelming for first-time users. GameZero offers a minimalist approach to CRYENGINE. It allows first time users to get a quick overview of using the engine’s core functionality. It can be used as starting point for creating several types of games.
Added: Support for 3ds Max 2016, Maya 2016 and MotionBuilder 2016
Keeping our DCC-import pipeline up-to-date, we have added support for 3ds Max 2016, Maya 2016 and MotionBuilder 2016.
