By 2021, the service had over 34,000 games with over 132 million monthly active users. By 2017, users purchasing games through Steam totaled approximately US$4.3 billion, representing at least 18% of global PC game sales according to Steam Spy. The service is the largest digital distribution platform for PC gaming, estimated around 75% of the market share in 2013 according to IHS Screen Digest. The platform also offers other digital content and Valve gaming hardware, including productivity software, game soundtracks, videos and VR headset Valve Index. Mobile apps to access online Steam features were first released for iOS and Android in 2012. Initially developed for Microsoft Windows operating systems, Steam was released for macOS in 2010 and Linux in 2012. Valve released a freely available application programming interface (API) called Steamworks in 2008, which developers can use to integrate Steam's functions into their products, including in-game achievements, microtransactions, and user-created content support. It provides the user with automatic game updating, saved game cloud synchronization, and community features such as friends messaging, in-game chat and a community market. Steam offers various features, like digital rights management (DRM), game server matchmaking, anti-cheat measures, social networking and game streaming services. It was launched as a software client in September 2003 as a way for Valve to provide automatic updates for their games, and expanded to distributing and offering third-party game publishers' titles in late 2005. WTF? I was able to get around this with Remote Desktop or TeamViewer but even that didn’t work sometimes.Steam is a video game digital distribution service and storefront by Valve. some steam games just didn’t like streaming and either failed to start at random or required me to go to the PC and hit ‘allow’ or something.

I fiddled around with virtual monitors, strange hdmi dummy stubs etc but never got it properly working.

I wanted to be able to stick my PC in a cupboard and just stream from it but that didn’t work out. inability to stream from a headless PC. Overall it work well but I ran into some issues which I do hope the new code in the new app will resolve:

I’ve been using the existing Steam app on and off over the past year to stream games from my 1060 equipped PC to my Mac laptop. Anything you can do with this, you could already do, but maybe people weren’t aware of it. This is just another version of the same app, but offered through the Mac App Store. Steam already offers a native game streaming app for the Mac. It’s important to recognise that this app offers almost nothing new.
