三星在最新的智能电视系列中直接增加了Steam 流式盒功能。

如果你身在美国并且拥有一款 2016 年或 2017 年的三星 UHD 电视，我们邀你一起帮助测试 Steam 流式盒应用，三星 Smart Hub 现已提供免费测试版。

该应用使用与 Valve Steam 流式盒相同的流式传输技术，使用户在看电视的时候轻松播放他们最喜爱的游戏，甚至在 HTC Vive 上观看 VR 游戏。

测试期间，此应用包括 60 FPS 的 1080p 视频播放并支持 Steam 控制器。随后于今年夏天发布的全球版本中，将增加对流式传输 4K 分辨率和额外控制器的支持。

注意：电视上的流式传输要求具备 Steam 控制器和不低于 5GHz 的高质量的网络连接。强烈建议使用有线网络。

请告诉我们你的感受，并在 Steam 流式盒讨论区 提供反馈和提出问题：http://gtm.you1.cn/app/353380/discussions/

The following changes have been released in the Beta version of the Steam Client. To get these changes, make sure you've opted into this on the remote computer:
https://developer.valvesoftware.com/wiki/Betas

• Increased desktop capture to 60 FPS on Windows 8 and newer
  
• Added an option to change desktop resolution to match the streaming client in the advanced host streaming settings
  
• Added a separate option to enable NVIDIA ShadowPlay capture in the advanced host streaming settings
  
• Attempt to recover if the graphics driver resets during streaming. Graphics driver resets may crash your game anyway, and you should disable hardware encoding if you are experiencing these often.

NOTE
The latest NVIDIA drivers have broken hardware encoding in Steam. Please revert to driver version 376.33 if you need that. We are working with NVIDIA to get a driver fix.
