SpectaES

How we calculate FPS

Specta estimates whether your PC runs a game and at how many FPS. It doesn't scan your computer: you enter your graphics card, processor and RAM.

Where the data comes from

Each game's minimum and recommended requirements and reference FPS come from the open PCGameBenchmarks dataset, published under CC BY 4.0. They calibrate their estimates against thousands of measured tests on known cards. Specta takes that data and adapts it: it combines it with your processor and RAM and extends it to other qualities and resolutions.

How we estimate

  • Graphics card: we compare your card with the game's reference cards and interpolate FPS at 1080p on High.
  • Quality and resolution: we apply average factors (for example, 1440p performs at about 72% of 1080p and Ultra at about 82% of High).
  • Processor: we calculate an FPS ceiling from your processor and what the game asks for. If your processor can't go higher, the card can't either.
  • RAM: if you have less than the game asks for, we lower performance.
  • Caps: some games are capped (for example at 60 FPS) and we respect that.

Margin of error

These are estimates for typical cases. A margin of up to 30% is normal (about 40% on integrated graphics). That's why we show a range instead of an exact number. Real results change with drivers, settings, temperature, game updates and the scene. We don't include ray tracing, DLSS, FSR or frame generation.

Games without official requirements

For games not yet out on PC, like GTA 6, we estimate from how they run on consoles and how games are usually optimized for PC, and we always label it as an unofficial estimate.

Help us improve

If a game runs differently for you, tap “Got different FPS?” in the result and tell us your real FPS. We use those reports to tune the estimates.

Shopping recommendations

When we suggest a part, we pick the one that adds the most FPS for that game among current models. Some shopping links are affiliate links: if you buy, we may earn a commission at no extra cost to you. It doesn't change what we recommend.
