In-Browser Demo Playback

Demo Playback is a GOTV-style video viewer that runs the actual demo on a GPU node and streams it back to your browser. Unlike the 2D/3D replay (which redraws the round from parsed data), this is the real game render — so you get true player POVs, weapon view models, and in-game HUD, with no CS2 install required.

When you start playback, a GPU pod boots (allocating a GPU, launching Steam and CS2, loading the demo) before the stream begins. If a map has more than one demo, you can pick which one to watch.

What you can do

• Spectate any player — jump between the ten player slots to follow whoever you want.
• X-ray — see players through walls (great for review; on by default).
• HUD — toggle the overlay and switch between horizontal and vertical layouts.
• Autodirector — let the spectator camera follow the action automatically, or drive it yourself.
• Round and kill navigation — jump round-to-round or kill-to-kill.
• Scoreboard — hold to view the live scoreboard.

Streamers can also create clips directly during playback.

Admin controls

• Demo playback requires at least one GPU node with demo playback enabled, plus a Steam account in the pool for the pod to log in with.
• Who can start playback and who can spectate are controlled by minimum-role settings.
• The default HUD layout is configurable.
