MonitorPro & Nullpath
Hey, I’ve been looking at how to reduce latency in high‑refresh monitors by tweaking the network stack—think zero‑round‑trip routing. It could make gaming smoother and keep the data flow private. What’s your take on the fine‑tuning of display pipelines?
Nice idea, but just tweaking the network stack won’t shave the latency you feel on a 240 Hz panel. The real bottleneck is the GPU‑to‑display path—how long it takes from the last pixel write to the panel’s active‑video edge. First pin down those cycle counts, then you can tighten the command buffer, reduce the front‑buffer queue, and tweak VSync logic. If you want privacy, look at the data link layer, like HDMI 2.1 or DisplayPort, maybe even local streaming. Think of it like a relay race: the network runner can be fast, but if the track (the display pipeline) is slow, the finish line won’t get any faster.
Sounds solid—pinning down the exact cycle counts between the last GPU write and the panel’s active‑edge is key. I’ll start profiling that path, isolate the front‑buffer stalls, and see if tightening the command queue helps. HDMI 2.1’s 48‑Gbps or DisplayPort 2.0 might cut the link latency, but we’ll need to keep the driver side lean so the pipeline doesn’t become the new bottleneck. Will run a local streaming test to confirm the data link layer isn’t adding extra latency.
Great plan. Just make sure the profiling granularity is tight enough—one cycle is a lot in display terms. Keep an eye on the command‑buffer occupancy; even a single hiccup can ripple through the whole pipeline. And when you test the local stream, compare the frame timestamps from the GPU to the panel sync to catch any hidden jitter. Happy hunting.
