Great topic to dig into. The core misconception I see repeatedly is that client-side prediction and server reconciliation are competing systems when they’re actually a matched pair. The client applies your input locally for immediate feel, then buffers that input and resends it to the server, which is authoritative. When the server’s authoritative result arrives, the client reconciles—overwriting its prediction with the server truth and re-applying any unacknowledged inputs.

For anyone building a dynamic jitter buffer from scratch, the biggest mistake I see is treating the buffer size as a single knob when it really needs to be a function of recent RTT variance. I switched from a fixed 40ms buffer to an adaptive scheme that tracks the moving average of inter-arrival delays (roughly the last 32 packets) plus a couple of standard deviations, and it completely changed my feel for competitive shooters. The key insight is that you want to predict the next packet’s arrival using a linear extrapolation of recent jitter, then set the buffer to cover that prediction with a safety margin—usually around the 95th percentile of observed delay, not the mean. If you only chase the mean, you’ll get underflow stutters during bursty spikes, which is far worse for gameplay than running a slightly larger buffer. In titles like Valorant or CS2 where sub-200ms input latency matters, I keep my target at roughly 48-64ms of added delay and let the algorithm expand to 120ms+ only when it detects sustained congestion.

On the smoothing side, packet loss concealment and dynamic delay compensation work best when they’re decoupled. I run a separate smoothing filter (an exponentially weighted moving average on the render timestamp) so that even if the jitter buffer briefly expands, the game client sees a stable, interpolated state instead of visible frame pops.

The 0.03ms pixel response of QD-OLED completely eliminates motion blur without needing aggressive overshoot overdrive. 360Hz OLED feels smoother than 500Hz TN in practice.
