RTX 5090 frame time and refresh rate calculator

Convert FPS to frame time in milliseconds and see how it compares with your display refresh rate.

How it works

Frame time is how long each frame stays on screen, in milliseconds, and equals 1000 divided by your frames per second. At 60 FPS each frame lasts about 16.7 ms, at 120 FPS about 8.3 ms and at 240 FPS about 4.2 ms.

Enter your RTX 5090 frame rate and your display refresh rate to see how close you are to filling the display.
