Steam's native Game Recording is now available to all Steam users
After many, many months of several features being in beta and preview phases for both Steam and SteamOS, all Steam users can now play around with the latest features that this week's updates from Steam provide, with perhaps the biggest one being the native Game Recording feature that Steam has implemented.
The latest Steam Client update from November 5th added the brand new Game Recording feature by Steam, which offers players the option to record gameplay footage directly within Steam itself, without having to rely on any external screen capture tools or software. This last update was first introduced in the beta for SteamOS 3.6, which as of a few days ago, was released into the main Stable branch of SteamOS with version 3.6.19, but with the Game Recording feature missing. Now the latest update of the Steam Client and the subversion update of Steam OS 3.6.20 brings the missing feature to all Steam users to enjoy.
The main Game Recording settings are located beneath the Storage settings in Steam and it has 3 options by default, "Recording Off", "Record in Background"; which makes it so that recording automatically begins upon launching a game, and "Record Manually"; which toggles recording on or off depending on user input. Additionally, users will be able to turn recording on or off with the shortcut combination of the Steam button + A, and pressing Steam+Y will add a timeline marker to the recording. There's also options for maximum frame rate and video height for the recording as well as recording quality, and even an option to enable microphone recording (amongst some audio recording options if enabled).
Once a video has been recorded, Steam offers several options to share the video, be it through send it to another device, send it to phone, create a QR link to share with other people, or share to a chat. Some sharing options are limited by the length of the video. In case a video is too long, users can trim the video right from Steam by going into the Media setting.
Be wary though, as this new feature does take processing power from the system, which could cause a performance hit (-5 fps or so) when playing higher specs games, depending on what the system the recording is being made from.
