GAME & ENTERTAINMENT – PC & CONOLE GAMING PERFORMANCE CALCULATOR
Frame Time Consistency
A precise tool.
What is the Frame Time Consistency & How does it work?
Frame time consistency measures how stable the interval between rendered frames is during gameplay. A steady frame time prevents visual stutter and makes motion feel fluid, even when the scene becomes demanding.
Average FPS gives a broad view of performance, but the 1 % and 0.1 % low frame times expose the worst‑case moments that can cause noticeable hiccups. These low‑percentile values are critical for assessing real‑world smoothness.
Consistency\ Ratio\ =\ frac{T_{low}}{T_{avg}}
Consistency Ratio = proportion of low frame time to average frame time
A lower consistency ratio indicates that even the slowest frames are close to the average, resulting in a smoother gaming experience across the entire session.

Frequently Asked Questions
What is frame time consistency?
Frame time consistency measures how stable the interval between rendered frames is during gameplay, ensuring smooth motion even under demanding conditions.
Why is consistency ratio important?
The consistency ratio helps identify worst-case moments in performance that can cause noticeable hiccups, making it crucial for assessing real-world smoothness.
How do I interpret the consistency ratio?
A lower consistency ratio indicates more stable frame times, while a higher ratio suggests more variability and potential stuttering.
What does average FPS tell me?
Average FPS gives an overall view of performance, but it doesn't reveal the worst-case scenarios that affect gameplay smoothness.
How do low percentile frame times impact gameplay?
Low percentile frame times expose the moments when the game struggles most, which can cause noticeable stuttering or hiccups in motion.
Can I use this calculator for any type of game?
Yes, you can use this calculator for any type of game to assess and improve its frame time consistency and overall smoothness.
What should my target consistency ratio be?
A target consistency ratio below 1.0 is generally ideal, as it indicates that low percentile frame times are closer to the average FPS, resulting in smoother gameplay.
