Advanced Usage#
Sunshine will work with the default settings for most users. In some cases you may want to configure Sunshine further.
Performance Tips#
In Windows, enabling Enhanced Sync in AMD’s settings may help reduce the latency by an additional frame. This applies to amfenc and libx264.
Enabling Fast Sync in Nvidia settings may help reduce latency.
Configuration#
The default location for the configuration file is listed below. You can use another location if you choose, by passing in the full configuration file path as the first argument when you start Sunshine.
The default location of the apps.json is the same as the configuration file. You can use a custom
location by modifying the configuration file.

- Description
When enabled, Sunshine will pass through native pen/touch events from Moonlight clients.
This can be useful to disable for older applications without native pen/touch support.
- Default
enabled- Example
native_pen_touch = enabled

pactl info | grep Source # in some causes you'd need to use the `Sink` device, if `Source` doesn't work, so try: pactl info | grep Sink
- macOS
Sunshine can only access microphones on macOS due to system limitations. To stream system audio use Soundflower or BlackHole.
- Windows
tools\audio-info.exe
Tip
If you have multiple audio devices with identical names, use the Device ID instead.
Tip
If you want to mute the host speakers, use virtual_sink instead.
- Default
Sunshine will select the default audio device.
- Examples
- Linux
audio_sink = alsa_output.pci-0000_09_00.3.analog-stereo
- macOS
audio_sink = BlackHole 2ch
- Windows

ls /dev/dri/renderD* # to find all devices capable of VAAPI # replace ``renderD129`` with the device from above to lists the name and capabilities of the device vainfo --display drm --device /dev/dri/renderD129 | \ grep -E "((VAProfileH264High|VAProfileHEVCMain|VAProfileHEVCMain10).*VAEntrypointEncSlice)|Driver version"
To be supported by Sunshine, it needs to have at the very minimum:
VAProfileH264High : VAEntrypointEncSlice
Todo
macOS
- Windows
tools\dxgi-info.exe
Note
For hybrid graphics systems, DXGI reports the outputs are connected to whichever graphics adapter that the application is configured to use, so it’s not a reliable indicator of how the display is physically connected.
- Default

wlr |
Capture for wlroots based Wayland compositors via DMA-BUF. |
kms |
DRM/KMS screen capture from the kernel. This requires that sunshine has cap_sys_admin capability. See Linux Setup. |
x11 |
Uses XCB. This is the slowest and most CPU intensive so should be avoided if possible. |

nvenc_twopass#
- Description
Enable two-pass mode in NVENC encoder. This allows to detect more motion vectors, better distribute bitrate across the frame and more strictly adhere to bitrate limits. Disabling it is not recommended since this can lead to occasional bitrate overshoot and subsequent packet loss.
Note
This option only applies when using NVENC encoder.
Choices

- Default
disabled- Example
nvenc_spatial_aq = disabled
nvenc_vbv_increase#
- Description
Single-frame VBV/HRD percentage increase. By default sunshine uses single-frame VBV/HRD, which means any encoded video frame size is not expected to exceed requested bitrate divided by requested frame rate. Relaxing this restriction can be beneficial and act as low-latency variable bitrate, but may also lead to packet loss if the network doesn’t have buffer headroom to handle bitrate spikes. Maximum accepted value is 400, which corresponds to 5x increased encoded video frame upper size limit.
Note
This option only applies when using NVENC encoder.
Warning
Can lead to network packet loss.
- Default
0- Range
0-400- Example
nvenc_vbv_increase = 0
nvenc_realtime_hags#
- Description
Use realtime gpu scheduling priority in NVENC when hardware accelerated gpu scheduling (HAGS) is enabled in Windows. Currently NVIDIA drivers may freeze in encoder when HAGS is enabled, realtime priority is used and VRAM utilization is close to maximum. Disabling this option lowers the priority to high, sidestepping the freeze at the cost of reduced capture performance when the GPU is heavily loaded.
Note
This option only applies when using NVENC encoder.
Caution
Applies to Windows only.
Choices

Description |
|---|---|
disabled |
Use high priority |
enabled |
Use realtime priority |
- Default
enabled- Example
nvenc_realtime_hags = enabled
nvenc_latency_over_power#
- Description
Adaptive P-State algorithm which NVIDIA drivers employ doesn’t work well with low latency streaming, so sunshine requests high power mode explicitly.
Note
This option only applies when using NVENC encoder.
Warning
Disabling it is not recommended since this can lead to significantly increased encoding latency.
Caution
Applies to Windows only.
Choices
Value |
Description |

Note
This option only applies when using macOS.
Warning
Disabling realtime encoding might result in a delayed frame encoding or frame drop.
- Default
enabled- Example
vt_realtime = enabled
Software Encoder#
sw_preset#
- Description
The encoder preset to use.
Note
This option only applies when using software encoder.
Note
From FFmpeg.
A preset is a collection of options that will provide a certain encoding speed to compression ratio. A slower preset will provide better compression (compression is quality per filesize). This means that, for example, if you target a certain file size or constant bit rate, you will achieve better quality with a slower preset. Similarly, for constant quality encoding, you will simply save bitrate by choosing a slower preset.
Use the slowest preset that you have patience for.
