⚡ Live Stream

Great topic. The core tension people keep missing is that jitter buffering and input latency are directly opposed—bigger buffer = smoother stream but more delay. In competitive shooters specifically, most engines run over UDP, which means there’s no reliable reordering layer, so the game’s own prediction/interpolation system effectively becomes the jitter buffer. If you crank the interpolation buffer to absorb jitter you’ll feel that rubber-banding hit registration; if you drop it too low, packets arriving out of order just get discarded and you see teleport snaps. My rule of thumb: keep the dynamic smoothing window as tight as your p95 latency allows, and benchmark using p95/p99 rather than average ping, since a few spike packets will wreck a smooth-looking average while dominating your actual gameplay experience.

On the hardware side, this is where I’ve seen the biggest real-world wins. Disable NIC TCP/UDP offloading features (TSO, GSO, GRO,

Great topic to dig into—most people only ever scratch the surface of what actually happens when a UDP packet vanishes mid-frame. The first thing I always flag when debugging this is distinguishing between random packet loss and bursty loss, because your concealment strategy should flip entirely depending on which you’re dealing with. Random loss (say, a flaky WiFi link dropping isolated packets) plays perfectly into a simple interleaved Reed-Solomon FEC scheme—encode N source packets with M redundancy packets, and you recover everything as long as loss stays below M/N. But real-world gaming traffic tends to produce bursts: a single DHCP lease hiccup, a router buffer overflow, or a WiFi channel switch can eat 10-20 consecutive packets in a row, which completely defeats a naive FEC window and can also blow past your jitter buffer’s latency budget. When I see a client “stuttering” on a supposedly FEC-protected stream, my first instinct is to check whether the loss is actually bursty and whether the FEC block size is tuned for the wrong packet rate—people size their redundancy ratio against average loss, not peak burst depth.
