NOTE:
This information is particularly relevant for game studios and small indie teams.


There can be issues with Steam - In-Game Recording running in the background, unvoluntarily. Depending on the context, this can cause massive performance issues.

Steam > Settings > Game recording


Notably for situations where a user would be remotely using a Gaming PC and that gaming PC would have BackgroundRecording set to ON, unvoluntarily. That could negatively affect video streaming and make a game totally unplayable.


I found the file that handles the GameRecording settings
0 = Off
1 = Background Recording
2 = Manual Recording


Path: C:\Program Files (x86)\Steam\userdata\UserID_Number\config  

File: localconfig.vdf

Code sample:
"GameRecording"
{
"BackgroundRecordMode"  "0"
}

Now all you have to do is create a script that runs on multiple devices.
A script that runs at the Windows startup and sets this feature to 0 .
