Why is Interact slow or laggy on my computer?
Interact runs recognition in the browser on zone crops. Heavy pages, large zones, many zones, or a weak machine can feel laggy. Shrink the zone, use one Interact zone when possible, and avoid continuous fullscreen extras the product does not support.
Prerequisites
Interact is on.
Steps
Reduce work
- Keep the zone tight on the subtitle line — not the whole player.
- Prefer one Interact zone over several overlapping ones.
- Close unused tabs if the browser is already under memory pressure.
What not to expect
- Cover does not OCR every frame; Interact still costs CPU when the line changes.
- The subtitle panel is not injected into site fullscreen the way some desktop tools do.
