How Many FPS Can My PC Run? Free Calculator & Bottleneck Tool

Estimate your average Frames Per Second (FPS) in popular games.

Methodology

How this calculator works

FPS model 2026.07 produces a planning range from a game reference profile and the selected 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

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.
