FPS and Refresh Rate Matcher
Check whether a monitor can display every distinct frame your system produces and whether the PC can feed every refresh cycle.
Worked planning example
FPS and Refresh Rate Matcher
This reproducible example shows the inputs, formula outcome and decision the calculator supports before you enter your own hardware.
Example inputs
110 FPS · 144 Hz
Calculated reading
110 ÷ 144 = 76.4% · +34 Hz · 9.09 ms
How to use it
FPS above refresh rate can still reduce input latency, but the display cannot show more complete refreshes per second than its rated frequency. Adaptive sync changes pacing, not the basic ratio.
The tool compares FPS and hertz directly, calculates utilization of the refresh ceiling, and converts both values to frame-time budgets.
How to interpret the result
FPS above refresh rate can still reduce input latency, but the display cannot show more complete refreshes per second than its rated frequency. Adaptive sync changes pacing, not the basic ratio.
Calculation methodology
The tool compares FPS and hertz directly, calculates utilization of the refresh ceiling, and converts both values to frame-time budgets.
The calculator runs in your browser from the values you select. Estimates use transparent planning rules and the site’s normalized hardware data; they are not lab benchmarks.
Formula or model used
Display use (%) = min(FPS / refresh rate, 1) x 100
Calculation steps
- Divide FPS by refresh rate for display utilization.
- Find excess FPS or unused refresh headroom.
- Compare render and refresh intervals in milliseconds.
Assumptions and limitations
- Actual refresh behavior depends on adaptive sync, V-Sync and frame caps.
- Response time, scanout, latency and frame pacing are not predicted.
