What is frame time and why does it matter?

Frame time is the number of milliseconds each frame takes to render. While FPS tells you the average rate, frame time reveals consistency. Two rigs can both show "100 FPS" but one may have spikes to 50 ms that cause visible stutters — frame time exposes this immediately.

What FPS do I need for a 144 Hz monitor?

You need at least 144 FPS to fully utilize a 144 Hz display. Each frame must render in under 6.94 ms. Anything lower means the monitor repeats frames, wasting the refresh-rate advantage.

Is 60 FPS still acceptable for competitive gaming?

60 FPS (16.67 ms frame time) is playable but competitive players prefer 144 FPS or higher. Lower frame times reduce input latency and make motion appear smoother, giving a measurable edge in fast-paced shooters.

How do I interpret the frame time budget breakdown?

The budget shows how the total frame time is divided between GPU rendering, CPU simulation, and display pipeline overhead. If GPU time alone exceeds your target frame time, you are GPU-bound and need to lower graphics settings or upgrade hardware.

What is the difference between average FPS and 1% low FPS?

1% low FPS represents the bottom 1% of frame rate samples — the worst-case spikes. A large gap between average FPS and 1% low means inconsistent framing and noticeable stutters, even if the average looks acceptable.

Does higher refresh rate always feel smoother?

Only if your GPU can sustain matching FPS. A 240 Hz monitor running at 80 FPS will repeat frames 3x per refresh cycle, producing no benefit over a 60 Hz display at the same FPS. Match your FPS target to your refresh rate for full benefit.

Summary

Convert FPS to frame time, find recommended FPS for any refresh rate, and analyze your frame time budget for smooth gameplay.

How it works

Enter your current FPS or pick a target monitor refresh rate.
The tool divides 1000 ms by the FPS value to get the frame time per frame.
Frame time is compared against quality thresholds to rate your performance tier.
The frame time budget panel splits the 16.67 ms (60 fps) budget into render, CPU, and display overhead.

Use cases

Check whether your GPU delivers consistent 1 ms frame times at high refresh rates.
Find the minimum FPS needed to match your 144 Hz, 165 Hz, or 240 Hz monitor.
Diagnose stuttering by comparing average FPS frame time against 1% low frame time.
Evaluate whether upgrading from 60 Hz to 144 Hz is worthwhile given your current FPS.
Quickly convert a benchmark FPS score into a frame time for latency-sensitive games.
