  "description": "NVIDIA Low Latency Off versus Ultra with Reflex disabled: eight measured CS2 tests, frame timings and downloadable results.",
  "verdict": "Off had better 1% lows and p99 in this test",
  "conclusion": "Ultra recorded a 10.16% lower median 1% low and a 7.76% higher p99 frame time. All four pairs favored Off for these metrics, with non-overlapping ranges. Median average FPS was 1.98% lower with Ultra, narrowly below the declared 2% decision threshold. This does not establish which setting has lower input latency.",
