This 3DMark score validation warning appears when the benchmark frame rate exceeds the NVIDIA Max Frame Rate setting.

The NVIDIA Control Panel includes a Max Frame Rate setting that lets you set the max frame rate for a 3D application or game. This feature can help you save power, reduce system latency, or stay within a specific Variable Refresh Rate range on a G-SYNC or G-SYNC Compatible display.

If the Max Frame Rate is set too low, it will artificially limit the frame rate in 3DMark, resulting in an inaccurate score.

To get a valid 3DMark score, open the NVIDIA Control Panel and disable the Max Frame Rate setting while benchmarking.
