How SpecBeacon FPS checks work

Pick a game, choose your GPU, then adjust CPU, RAM, resolution, and target FPS if you want a tighter estimate.

SpecBeacon compares your setup against benchmark coverage and points to the first upgrade that meaningfully improves the result.

Use the full guide pages on About and Terms if you need more detail on how the service is operated.

How does SpecBeacon estimate FPS?

SpecBeacon compares your selected GPU, CPU, RAM, and resolution against benchmark rows in the catalog and projects the closest likely result.

Can SpecBeacon suggest upgrades for higher FPS?

Yes. Raise the target to 90 or 120 FPS and SpecBeacon will suggest the first GPU upgrade worth making when enough benchmark coverage exists.

Do I need to enter every PC part?

No. GPU is the most important input. CPU, RAM, and target FPS make the estimate and upgrade guidance more precise.
