        "One warmup per driver was excluded; four measured tests per driver. All baseline tests preceded the new-driver tests; this was not an interleaved comparison.",

        "Saved CFG hashes, Steam overlay state (off), game build and captured Windows conditions matched. Driver-defined defaults changed; this is a driver-package comparison, not a claim that every internal driver setting was identical.",
        "A new predefined DRS entry (548384728 = 1) was left untouched. NVIDIA Ansel policy 271965065 was 0 in both groups.",
        "Display alias changed from DISPLAY1 to DISPLAY6; resolution, refresh rate, position and orientation matched.",
        "The second group used a bounded NVML shutdown fix; sensor cadence and the measured PresentMon window were unchanged.",
        "Both sessions completed with restoration verified and no cleanup errors. Four tests on one system do not establish statistical certainty, live-match performance or physical input latency."
