- Consumer grade Nvidia cards are software limited to a specific number of encodes. See
`Video Encode and Decode GPU Support Matrix <https://developer.nvidia.com/video-encode-and-decode-gpu-support-matrix-new>`__
for more info.
- You can usually bypass the restriction with a driver patch. See Keylase's

Sunshine provided controller (connected to the guest) is the "first" one. In Linux this can be accomplished on USB
devices by finding the device in `/sys/bus/usb/devices/` and writing `0` to the `authorized` file.
Packet loss

Packet loss (Buffer overrun)
----------------------------
If the host PC (running Sunshine) has a much faster connection to the network
than the slowest segment of the network path to the client device (running
Moonlight), massive packet loss can occur: Sunshine emits its stream in bursts
every 16ms (for 60fps) but those bursts can't be passed on fast enough to the
client and must be buffered by one of the network devices inbetween. If the
bitrate is high enough, these buffers will overflow and data will be discarded.
This can easily happen if e.g. the host has a 2.5 Gbit/s connection and the
client only 1 Gbit/s or Wifi. Similarly a 1 Gbps host may be too fast for a
client having only a 100 Mbps interface.
As a workaround the transmission speed of the host NIC can be reduced: 1 Gbps
instead of 2.5 or 100 Mbps instead of 1 Gbps. (A technically more advanced
solution would be to configure traffic shaping rules at the OS-level, so that
only Sunshine's traffic is slowed down.)
Packet loss (MTU)
-----------------
Albeit unlikely, some guests might work better with a lower `MTU
<https://en.wikipedia.org/wiki/Maximum_transmission_unit>`__ from the host. For example, a LG TV was found to have 30-60%
packet loss when the host had MTU set to 1500 and 1472, but 0% packet loss with a MTU of 1428 set in the network card
