About

For PC gamers, the metric that matters most is FPS (Frames Per Second). Building a rig or upgrading components is an investment, and knowing what performance to expect is crucial to avoid buyer's remorse. This PC Gaming FPS Calculator utilizes a vast database of hardware benchmarks to estimate real-world performance.

By cross-referencing the single-core and multi-core capabilities of processors with the rasterization and texture fill rates of graphics cards, this tool provides an accurate estimation of average FPS. Whether you are aiming for 144Hz in competitive shooters or a stable 60 FPS in 4K open-world RPGs, this tool helps you visualize the capabilities of your hardware configuration.

Formulas

The estimated FPS is derived from a composite score of the CPU and GPU, adjusted for the specific optimization demands of the selected game engine and resolution scaling.

FPS_est ≈ (Base_game × Score_gpu × Score_cpu) ÷ Factor_res

Resolution scaling follows an inverse power law where 4K requires exponentially more GPU processing power than 1080p:

Factor_res ∝ (Pixels_width × Pixels_height)^0.75

Reference Data

Game Title	Resolution	Settings	Target FPS (Competitive)	Target FPS (Cinematic)
Cyberpunk 2077	1080p	Ultra / RT On	N/A	60+
Valorant	1080p	Low / Comp	240+	144+
Call of Duty: Warzone	1440p	High	144+	100+
Elden Ring	4K (2160p)	Max	N/A	60 (Locked)
Fortnite	1080p	Performance	240+	144+
GTA V	1440p	Very High	120+	60+
Red Dead Redemption 2	1440p	High	N/A	60+

Frequently Asked Questions

These estimates are based on aggregated benchmark data. While highly accurate for average scenarios, real-world performance can vary due to thermal throttling, background processes, driver versions, and specific in-game scenes.

Resolution determines the number of pixels the GPU must render. 4K (3840x2160) has 4x the pixels of 1080p. While the drop isn't perfectly linear due to CPU bottlenecks at lower resolutions, the GPU load increases massive at higher resolutions.

Yes, particularly in CPU-bound scenarios or open-world games. Faster RAM (e.g., DDR5 6000MHz vs DDR4 2400MHz) can improve 1% low FPS, making gameplay feel smoother, even if the average FPS only increases slightly.

Common causes include thermal throttling (overheating), outdated drivers, Ray Tracing being enabled (which is very demanding), or background applications consuming system resources.
