Present view: screens to show

Un-tick screens you never present. Numbers 1–9 follow what is shown. Saved on this device only.

Live preview

Max: lowest delay and highest frame rate OBS can give, bigger pictures, every screen as fast as possible. It uses a lot of CPU and graphics-card power, so do not use it while streaming on one PC. Live: about 15 fps. Saver: about 2 fps, much lighter. Off: no pictures at all, so OBS spends nothing on previews. Use Off or Saver while streaming. The eye button in the top bar switches it quickly.
