What Is 1% Low FPS and Why It Matters

Average FPS tells you how fast a game runs overall. But it does not tell you how smooth it feels. That’s where 1% Low FPS becomes important.

The 1% Low measures the average of the slowest 1% of frames during gameplay. It highlights stutters, lag spikes, and inconsistent frame delivery.

The Formula Used

First, collect all FPS samples. Calculation follows these steps:

  1. 1% Count: Total Frames × 0.01
  2. 1% Low FPS: Sum of Lowest 1% Frames ÷ Number of Those Frames

For deeper testing, you can also calculate 0.1% Low using: 0.1% Count = Total Frames × 0.001.

Why High 1% Lows Matter

Two systems may both show 70 FPS average. However, if one has a 1% Low of 65 FPS and another has 45 FPS, the first system will feel significantly smoother. Competitive gamers rely on stable frame delivery to maintain consistent aiming and reaction times.

Frequently Asked Questions

Why is my 1% Low so much lower than my Average FPS?
This usually indicates a "bottleneck" or background software interference. When the CPU or GPU can't keep up for even a fraction of a second, frame times spike, dragging down the 1% metric even if the average remains high.
What is a good Smoothness Score?
A score of 90+ is excellent and feels perfectly fluid. 75-89 is good but might have rare micro-stutters. Anything below 60 will be noticeably "choppy" for enthusiast gamers.
