Peeker’s Advantage Physics: Round-Trip Latency and Angle Geometry: Advanced Implementation and Real-World Architecture

[Luke Gray]

Alright, let’s talk real numbers here. I’ve been benchmarking my setup (240Hz panel, 5ms monitor response, 15ms total system latency) and I keep hitting a wall on how peeker’s advantage actually scales with round-trip latency. Everyone cites the “you’re peeking, they’re static” advantage, but nobody breaks down the angle geometry—specifically, how the effective exposure window changes as your view angle relative to the wall increases. At what horizontal angle does the extrapolation window on the opponent’s client actually close the gap, and is there an empirical threshold where the advantage flips to favor the static player?

Second question: I’m seeing wild frame-to-frame variance in my interpolation buffer (33ms target) when the network jitter pushes above 20ms. Are people running server-side clamping to prevent the extrapolation artifacts that make targets “snap” backward during a peek, or is this purely an engine-level cvar situation? And has anyone actually benchmarked the human reaction threshold against sub-50ms peek windows—like, is 120ms RTT still reactable by pro-level reflexes, or does the math say you’re dead regardless of skill? What’s your actual measured setup and numbers?
