WattsyHow this FPS calculator works
Each CPU and graphics card has a relative gaming performance score based on typical benchmark results. The calculator estimates how many frames each part could deliver on its own at your resolution and game type, then takes the lower of the two — that's your frame rate. It shows a range because real results swing a lot between games, settings and driver versions.
"AAA, high settings" assumes a demanding modern single-player game. "Competitive shooter" assumes a lighter, well-optimized game like the popular tactical and battle royale shooters at competitive settings.
Do you need to hit your monitor's refresh rate?
No. With G-Sync or FreeSync, anything inside the monitor's variable refresh range looks smooth. A 144Hz monitor still feels better than a 60Hz one at 90 FPS. Matching the refresh rate matters most in competitive shooters, where every frame reduces input delay.
Frequently asked questions
What FPS do I need for a 144Hz monitor?
Ideally around 144 FPS, but anything from roughly 80 FPS up will still feel noticeably smoother than 60Hz, especially with G-Sync or FreeSync on.
Should I cap my FPS?
Capping a few frames below your refresh rate (for example 141 FPS on a 144Hz monitor) is a common way to keep G-Sync or FreeSync active, reduce stutter and lower power use.
Is upscaling worth turning on?
Usually, at 1440p and 4K. Quality-mode upscaling typically adds 25–50% more FPS with little visible difference. It helps much less when your CPU is the limit.
