Why is my actual FPS different from the calculator’s estimate?

Real-world FPS can vary due to factors like drivers, cooling, RAM speed, background processes, and specific in-game settings. The calculator provides a baseline estimate for most users.

Can I use the FPS calculator for future games?

Yes, but unreleased games use a speculative planning profile with wider uncertainty until reliable PC performance evidence is available. Treat that result as an early estimate, not proof of launch-day performance or a purchase guarantee.

Do resolution and graphics settings affect FPS results?

Yes. Running games at higher resolutions (1440p, 4K) or ultra settings requires more GPU power, which lowers FPS compared to playing at 1080p or medium settings.

What do average FPS and 1% low FPS mean?

Average FPS summarizes overall frame output during a test. The 1% low describes performance during the slower portion of the run and helps indicate smoothness or stutter. On this calculator, both are planning estimates rather than values captured from your PC.

Does monitor refresh rate limit FPS?

A PC can render more FPS than the monitor's refresh rate, but the display cannot show more complete refreshes per second than its rated Hz. Frame caps, V-Sync and variable refresh rate can change pacing, tearing and the FPS you observe.

How do DLSS, FSR, XeSS and frame generation affect FPS?

Upscaling can improve GPU-limited performance by rendering at a lower internal resolution and reconstructing the output, but gains vary by game and mode. Frame generation inserts additional displayed frames, so generated or displayed FPS should not be treated as identical to the underlying rendered FPS or input response.

Q: How does the FPS calculator work?

The calculator combines normalized CPU and GPU performance indexes with a game reference profile, then adjusts the result for resolution, quality, upscaling and selected memory options. It produces a planning range, midpoint and estimated 1% low—not a measured benchmark of your PC.

Reading the estimate

How Many FPS Will I Get? How to Read the Estimated Range

The calculator returns a range because frame rate changes with the scene, game patch, drivers, cooling and background activity. Use the midpoint for planning, then use the low and high estimates to understand realistic variation.

What each FPS number tells you

Result	What it means	How to use it
Low estimate	A heavier scene or less favourable system condition.	Treat it as the safer expectation for demanding gameplay.
Midpoint	The centre of the modelled range for the selected setup.	Use it to compare configurations under the same inputs.
High estimate	A lighter scene or more favourable system condition.	Do not treat it as a guaranteed minimum.
1% low	A measure of slower frames rather than the overall average.	Compare it with average FPS to judge smoothness and stutter.

Why 1080p, 1440p and 4K change the result

Resolution changes how much work the GPU must do for every frame. The same CPU and GPU can therefore produce a different balance at each display target.

Target	Typical effect	What to watch
1080p	Lower pixel load can expose CPU or frame-rate limits sooner.	CPU per-core load, refresh-rate caps and high-FPS consistency.
1440p	Higher GPU demand often creates a more balanced gaming workload.	Graphics preset, upscaling mode and available VRAM.
4K	The GPU renders four times as many pixels as 1080p.	GPU load, VRAM use, upscaling and the selected quality preset.

Checking FPS on a laptop?

A mobile CPU or GPU can perform differently from a desktop part with a similar name. Laptop power limits, cooling and graphics switching can materially change the result, so select the closest mobile model and verify with an on-device test.

Action RPG

Cyberpunk 2077

Cyberpunk 2077 is demanding on both CPU and GPU. For the current Update 2.0 requirements, 12 GB RAM and an SSD are the minimum starting point. Ray tracing, crowd density and resolution can change the limiting component, so compare the official tier first and then model your exact build.

Forza Horizon 5

Forza Horizon 5 can run on a PC that meets the official minimum, but meeting that tier does not guarantee your preferred resolution, settings or frame rate. Its open world can shift load between the processor and graphics card, while resolution, anti-aliasing and environmental detail raise GPU demand. Compare the official tiers first, then model and test your exact build.

Methodology

How this calculator works

The FPS model 2026.07 estimates a planning range from the selected game profile, hardware and graphics settings. It is not a measured benchmark.

Inputs

CPU and GPU indices, game profile, resolution, quality preset, upscaling, anti-aliasing, RAM capacity and speed, VRAM pressure and storage type.

Calculation model

A per-game 1080p High reference is scaled by weighted CPU/GPU capacity, resolution and quality factors, supported upscaling, memory pressure and smaller system modifiers.

How to read the result

Results include a likely range, planning midpoint, estimated 1% low and likely limiting component. Wider uncertainty is used for speculative game profiles.

Estimated FPS = game reference × hardware scale × resolution × quality × supported modifiers

Important limitations

Patches, drivers, map or scene complexity, background tasks, thermals and game-specific settings can materially change FPS. Compare against independent benchmarks.

Understanding Your Gaming Performance: The FPS Calculator

In the world of PC gaming, Frames Per Second (FPS) is the ultimate measure of performance. It represents how many individual images your computer can display every second, directly translating to the smoothness of your gameplay. A high, stable FPS means a fluid, responsive experience, while a low FPS leads to stuttering and lag.

Why Estimate Your FPS?

Knowing your potential gaming performance before you buy a new game or upgrade a component is crucial. It empowers you to make informed decisions, manage expectations, and avoid the disappointment of a purchase that your PC can't handle.

How Does the FPS Calculator Work?

Our calculator provides an indicative estimate from normalized CPU and GPU scores. It considers three key factors:

Your CPU's Power: The processor handles the game's logic, physics, and AI. In many eSports titles, the CPU is the primary driver of high frame rates.
Your GPU's Power: The graphics card is responsible for rendering the visuals. In graphically intense AAA titles, the GPU does the heaviest lifting.
Your Target Resolution: Playing at 4K requires your GPU to render four times as many pixels as 1080p, which has a massive impact on the final FPS.

Low FPS? Your Next Steps to a Better Gaming Experience

Step 1: Diagnose the Core Issue with Our Bottleneck Calculator

Before you consider an upgrade, you need to know why your FPS is low. Is your powerful GPU being held back by an older CPU? Or is your GPU simply not strong enough for your desired settings?

Our PC Bottleneck Calculator compares internally normalized CPU and GPU scores. Use the relative score gap as a planning clue, not as measured FPS loss or a definitive diagnosis.

Step 2: Ensure You Have Enough Power for an Upgrade

If you're planning a GPU upgrade to boost your FPS, there's one critical step you can't ignore: your Power Supply Unit (PSU). Modern graphics cards can be very power-hungry.

Use our PSU Wattage Calculator to ensure your power supply can handle any new hardware you're considering.
