I very much don't trust that article as a baseline. YMMV but I measured with a 240hz camera with a mid-high tier computer and a 144hz monitor in 2018 and a nice computer w/ 165hz in 2025 and I never got the huge latencies he experienced, I had click to photon of something like 10 frames max, so 42ms, with the average IIRC being closer to 5 frames.
