See how your FPS matches your monitor refresh rate and if you should cap it.
Common refresh rates:
Match quality
FPS
Frame time
FPS per Hz
Type the FPS you get in game, for example 120 or 165.
Type your monitor refresh rate in Hz, such as 144.
Refresh rate (Hz) is how many times per second your monitor draws a new image. FPS is how many frames your PC renders per second. When they do not line up, you get screen tearing (FPS above Hz) or stutter and judder (FPS below or not matching Hz).
Ideally FPS matches Hz exactly, or is an exact multiple or fraction of it. G-Sync and FreeSync monitors adapt their refresh to your FPS to eliminate tearing. If you play with V-Sync on a fixed refresh panel, cap your FPS just below the refresh rate for the lowest input lag.
Higher FPS still reduces input lag even on a fixed refresh monitor, but without a sync technology it causes screen tearing. With G-Sync/FreeSync, higher FPS up to the refresh cap is always better.
For a 144 Hz fixed panel, cap at 143 or 140. For G-Sync/FreeSync, cap 2-3 FPS below the max refresh (for example 141 on a 144 Hz monitor) to stay inside the sync range.
Judder is visible unevenness in motion caused by FPS not being an exact multiple of the refresh rate, such as 60 FPS on a 144 Hz monitor, where frames are shown for unequal durations.
