Answers to common questions.
FPS = frames rendered / seconds, or 1000 / frame time in ms. For estimates, RunFps combines GPU and CPU benchmark scores (0-100) with a game performance curve, plus RAM, resolution and quality settings to predict FPS. For real FPS, use an in-game overlay or the RunFps FPS Calculator.
Use the RunFps Settings Optimizer for target FPS, then: lower resolution and quality preset, update GPU drivers, enable XMP/DOCP for RAM, close background apps and overlays, clean thermals, and upgrade the bottlenecked part (check the Bottleneck Calculator). Even small tweaks can add 20-40% FPS.
Update GPU drivers, lower graphics settings and resolution, close background processes, check CPU/GPU temperatures for throttling, run the Bottleneck Calculator to find the limiting part, ensure dual-channel RAM, and scan for malware. If FPS stays low, a GPU or CPU upgrade gives the biggest gain.
60 FPS is smooth and good for most games. 120 FPS is noticeably smoother with lower input lag, ideal for competitive shooters on a 120/144Hz+ monitor. Above your monitor refresh rate you see diminishing returns, so match FPS to your display for the best experience.
At 60 FPS, 1 frame = 16.67ms (1000ms / 60). At 120 FPS it is 8.33ms and at 30 FPS it is 33.33ms. Lower frame time means smoother motion and less input lag.
FPS estimates are based on GPU and CPU benchmark scores interpolated against real game performance data. Actual FPS may vary by ±10-15% depending on your specific system configuration, drivers, background processes, and other factors. We recommend using the estimates as a general guide rather than an exact prediction.
Each GPU and CPU has a benchmark score (0-100). Each game has a performance curve mapping GPU scores to FPS. We combine this with your CPU score, RAM configuration, resolution, quality preset, and other settings to estimate your FPS. All calculations run locally in your browser — no data is sent anywhere.
Use the FPS Calculator — select your GPU, CPU, and the game to see estimated FPS at different presets and resolutions. You can also check the Games Library for per-game FPS estimates across hardware tiers.
Each game page in the Games Library includes RAM, VRAM, and storage requirements. You can also see estimated FPS across budget to ultra hardware tiers to know exactly what to expect.
Hardware is ranked by a composite benchmark score (0-100) based on real-world gaming performance. You can compare specs side by side and see estimated FPS differences across popular games using a standardized test system.
Upgrade suggestions pick the next sensible step above your current part and filter it so it pairs well with your other component — we never recommend jumping several tiers at once. The estimated FPS gain is computed by simulating your system with the upgraded part. Actual performance depends on your full system, but relative ranking is a reliable indicator.
If your laptop has a dedicated GPU, you can look it up in our database. Select your laptop's GPU and CPU in the FPS Calculator to get estimates. Note that laptop GPUs typically perform slightly below their desktop counterparts due to thermal and power limits.
