What are 1% lows?

A 1% low is a summary intended to describe slower frames, but tools use different calculation methods.

QUICK EXPLANATION

Treat it as a comparison, not a universal score

A low value can point to frame-time dips that an average FPS hides. Check whether the tool reports a percentile, an average of the slowest frames or another metric.

Results depend on the capture window, scene and calculation method.

Result: Comparisons are most useful when the same tool, capture duration and repeatable game scene are used.

How to check it

Keep the average FPS and frame-time graph alongside the 1% low. Avoid comparing numbers from different benchmark tools as if they were defined identically.

Check: Repeat the same capture and confirm the result is consistent before drawing a conclusion.
