Linux Users Can Now Play Windows Games on Steam with In-Home Streaming
The In-Home Streaming feature allows users to stream games from a Windows operating system to a Linux-powered machine that also runs Steam. This is the solution proposed by Valve that practically enables Linux gamers to play any Windows-only titles, although it's rather cumbersome, to say the least.
Like any other major Steam update, the latest has been preceded by a flurry of smaller ones in the Beta branch of the software. This is basically just a collection of those features and fixes that were already available for all users of Steam Beta.
