Lag and latency

Improve smoothness through bandwidth, quality, encoding and network path.

Remote lag is not always "slow internet". More often it is limited upstream bandwidth, a relayed path, quality set too high, or a loaded host. Follow these steps in order and the experience usually improves clearly.

Find the bottleneck

The session shows current latency, frame rate and whether the link is direct. If it says relayed, peer-to-peer failed and the relay node affects latency.

  • Check the latency and frame rate readout
  • Confirm direct or relayed
  • Compare with another device on the same network
  • See whether lag clusters at specific times

Lower quality demands

Switch to the Smooth preset, disable wallpaper and animation, and reduce resolution and frame rate — this alone can cut the data volume by more than half.

  • Switch to the Smooth preset
  • Disable wallpaper and window animation
  • Lower resolution and frame rate
  • Turn off audio temporarily

Improve the network path

Prefer wired connections and off-peak hours; if other programs saturate the host uplink (cloud uploads, video calls), pause them first.

  • Use wired instead of Wi-Fi
  • Pause uploads and downloads using the uplink
  • Avoid peak hours
  • Stop bandwidth-hungry background sync

Host load

High CPU or disk usage on the host slows capture and encoding directly. Check for updates, antivirus scans or large build jobs.

  • Check CPU and disk usage
  • Pause antivirus scans and system updates
  • Close unneeded heavy programs
  • Add memory if the machine is short

FAQ

Latency is low but it still stutters.

Low latency with a low frame rate usually means limited encoding power or bandwidth. Lower quality and resolution and watch again.

Would a faster broadband plan help?

Upstream matters most. Many home plans have fast download and slow upload, so measure upstream before changing plans.
