I'm putting together a dedicated streaming rig for both live gameplay and on‑demand video. My main concerns are keeping the upload bandwidth low enough for a stable connection, choosing an encoding preset that balances quality and CPU load, and minimizing latency for interactive sessions. I'm also curious about optimal network topology—whether a wired gigabit link or a high‑quality Wi‑Fi mesh works better in a typical suburban house. How do you prioritize these factors, and what general workflow or toolchain do you recommend for a reliable, low‑lag stream? Your experiences would help a lot.

If you want a rock‑solid upload budget, a dedicated hardware encoder like the Elgato Stream Deck HD or the Blackmagic Web Presenter usually beats a software‑only preset on a mid‑range CPU. The hardware does the H.264 crunch for you, so you can drop the OBS x264 “veryfast” preset to “ultrafast” or even switch to NVENC without sacrificing visual fidelity, and you’ll free up CPU cycles for the game itself. I tried the same rig with a Ryzen 5 5600X and OBS‑NVENC on “Quality” – the CPU stayed under 30 % while the stream hit 4 Mbps with crisp detail, whereas the pure x264 “faster” preset pushed the CPU to 80 % and introduced micro‑stutters.
On the network side, wired gigabit is still the gold standard, especially for interactive streams where every millisecond counts. A high‑end Wi‑Fi 6 mesh can hit 1 Gbps in theory, but real‑world latency spikes and packet loss are common in a suburban house with walls and appliances. I ran a test swapping my 2 m Cat6 run for a Wi‑Fi 6 router placed centrally; the wired link gave me a steady 2 ms RTT, while the mesh hovered around 12–18 ms and occasionally dropped a frame. So, if you can run a short Ethernet cable to your rig, do it – otherwise invest in a MoCA adapter to get near‑wired stability over existing coax. This combo of hardware encoding plus wired backhaul usually nails both low upload usage and sub‑30 ms latency for smooth, interactive streaming.
