TrueView Demo Playback Reconstructs the Observed Player's Original Experience

A new TrueView demo playback mode re-runs client-side prediction to reconstruct what the observed player actually experienced, including damage prediction effects, though very slow motion playback can still show small timing differences. It is disabled by default on old demos unless cl_demo_predict 2 is set. The update also fixes surf air acceleration and ramp jump-apex misidentification, an inconsistent sniper rifle unscope delay, and G3SG1 bolt animations.

G3SG1

misc

  • fixFixed a case where air acceleration was clamped incorrectly while surfing.
  • reworkAdded TrueView demo playback, which reconstructs the observed player's original experience more accurately by re-running client-side prediction.
  • reworkTrueView demo playback might not work properly on old demos and is disabled by default if the playback client version does not match the client version when the demo was recorded. You can set cl_demo_predict 2 to override this.
  • fixFixed a bug causing third person models to not animate smoothly.
  • fixFixed a bug causing time to lurch forward by one tick when unpausing a demo.
  • fixFixed developer console scrollbar to accept mouse clicks.

movement

  • fixFixed a case where slowly surfing up a ramp was handled incorrectly due to misidentification as a jump apex.

weapon

  • fixFix a bug causing "Delay Sniper Rifle Un-Scope after Shot" to be inconsistent.
  • reworkTrueView playback will show the effects of Damage Prediction, if it was enabled by the observed player at the time.
  • reworkTrueView does not reconstruct the precise timings of rendered frames, so some differences between the original player's experience and TrueView playback will remain, especially in very slow motion playback. The player's frame at the time when the mouse was clicked, which is used for hit registration, is shown accurately to the nearest demo playback frame. However, reaction effects such as recoil, muzzle flash, blood splatter, and ragdoll are delayed while playing the game by one or two frames due to the way CPU and GPU work is pipelined, and will not appear at the same time during demo playback.
  • reworkAnimation fixes for G3SG1 bolt.G3SG1
