Stream to 3D — Performance primer

This page explains the main performance bottlenecks and the quickest changes that improve smoothness in Play/Stream/Convert.

If you see an LVE0xx error code, start with Licensing & Activation and Error Codes.

Start here (fast improvements)

  1. Start with Half formats (HSBS/HTB) for compatibility and performance. See Settings → Format.
  2. If Play/Stream can’t stay smooth in real time, convert offline (Convert) for the best quality and smoothness. See Video File Conversion.
  3. If streaming, start with HTTP and test the stream URL locally first (same PC). See Streaming.

Why formats matter (Half vs Full)

Full formats (Full SBS/TB) keep more pixels per eye and are more demanding. Half formats (HSBS/HTB) reduce per-eye resolution and are often the most reliable starting point.

If you’re trying to diagnose a stutter/lag problem, reduce load first (Half formats, shorter clips) so you can isolate whether the issue is conversion, encoding, network, or playback.

Encoding, FFmpeg, and GPU drivers

Frame rate and interpolation

  • Higher frame rates and interpolation can improve smoothness, but they increase CPU/GPU load.
  • If performance is marginal, prefer settings that are stable in real time, or convert offline (Convert) for maximum quality.

Network limits (streaming)

  • Make sure the client device is on the same LAN/Wi‑Fi as the PC running Stream to 3D.
  • If streaming is unstable, reduce resolution and/or bitrate first.
  • If it works locally but not on the device, check VPN/firewall routing. See Streaming first checks.

Live/screen capture performance

Before contacting support

To get the fastest resolution, include:

  • Your store (Steam/Gumroad/Itch/etc) and Stream to 3D version.
  • What workflow you’re using (Play/Stream/Convert/Live capture).
  • What output format you selected (HSBS/HTB/Full, etc).
  • Logs from Logs & Diagnostics.
