Note: Note:
* The Windows key is not passed through by Moonlight, therefore Sunshine maps Right-Alt key to the Windows key * The Windows key is not passed through by Moonlight, therefore Sunshine maps Right-Alt key to the Windows key
* If you set Video Bitrate to 0.5Mb/s:
* Sunshine will use CRF or QP to controll the quality of the stream. (See example configuration file for more details)
* This is less CPU intensive and it has lower average bandwith requirements compared to manually setting bitrate to acceptable quality
* However, it has higher peak bitrates, forcing Sunshine to drop entire frames when streaming 1080P due to their size.
* When this happens, the video portion of the stream appears to be frozen.
* This is rare enough that using this for the desktop environment is tolerable (in my opinion), however for gaming not so much.
