Performance Tuning

[RussellAult]

So far I haven't seen anything really definitive about tuning the performance of Sunshine, so I thought I'd start the ball rolling and see what everyone else is doing.

My use-case: in-home game streaming, including first-person shooters
My goal: lowest possible round-trip latency without obvious visual sacrifices (e.g. screen tearing)

My current settings:

• On the host:
  • Hardware encoding
  • HEVC disabled
  • V-Sync disabled (in-game)
• On the guest:
  • Wired network connection
  • 1080p60 at 10 Mbit/s
  • V-Sync enabled

Things I haven't played around with much yet:

• On the host:
  • Encoder tweaks beyond disabling HEVC (What I'll try next; how did I miss these?!)
  • Running Sunshine as Administrator (Does GPU priority impact Sunshine's performance much?)
• On the guest
  • Trying more bitrates (Is lower actually faster? Do hardware encoders have a bitrate sweet-spot?)
  • Frame pacing (Won't this just slow things down?)

So far I'm reasonably happy with the setup's performance, although I feel like there might still be room for improvement. Does Sunshine have a function that will spit out realtime encoding latency statistics (like how Moonlight will display decoding latency statistics)?

I know this post is old, but in the process of migrating discussions I figured I would share something new.

New docs have a performance tuning section: https://docs.lizardbyte.dev/projects/sunshine/en/master/md_docs_2performance__tuning.html

Feel free to submit any tips/tricks as a PR.

this might not be useful here, but for a radius of ~2 rooms, using my pc's hotspot rather than my modem for moonlight on android is faster.

I think it was around 20ms latency shown in moonlight stats, it's been a while since I checked.

note: my modem is an old isp provided one, so this probably doesn't apply to a modern riced up modem or jeff geerling style pi router config.
