### adaptive_bitrate

<tr>
<td>Description</td>
<td colspan="2">
Allow supported Moonlight sessions to reduce the video bitrate during sustained network loss. Runtime
bitrate changes are currently supported by the Windows native NVENC backend. Recovery is gradual and
requires both a quiet period without new loss pressure and a fresh, healthy ENet RTT sample produced by a
reliable acknowledgement from Moonlight; the absence of FEC reports alone never permits an increase. The
controller never exceeds the bitrate requested by Moonlight or the configured `max_bitrate` ceiling.
Unsupported clients and encoders continue to use their fixed effective bitrate.
