3. Controller Support: It offers broad controller compatibility, supporting various input devices including Steam Controller, MFI controllers, and more, which means you can play with the controller you're most comfortable with.

Con

1. Performance Limitations: The quality of the streaming experience can be hindered by network instability. Any network lag, packet loss, or jitter may lead to noticeable latency or reduced visual fidelity, affecting gameplay.

2. Compatibility Issues: Not all games may be fully compatible with the Steam Link app. Users may encounter problems with unsupported titles or with games that require peripherals not supported by the streaming device.

3. Resource Intensive: Streaming games via Steam Link can be resource-intensive for the host PC. This means the computer must be sufficiently powerful to run games while also encoding video for streaming, which could impact performance on less capable systems.
