Gaming FPS Calculator for Popular Games

Planning an upgrade or wondering if your current PC can handle a specific title? The FPS calculator uses publicly available benchmark data to produce an approximate frame-rate estimate for common resolutions and quality presets. Whether you’re targeting 60 FPS at 4K or high refresh rate at 1080p, it gives you a reasonable ballpark before you spend money.

Looking to optimize your competitive gaming setup? Check out ourBest CS2 Settings Guide for 144-300+ FPSwith pro player configurations and NVIDIA/AMD optimization tips.

  • 1080p, 1440p, 4K, and Ultrawide resolution support
  • Supports Cyberpunk 2077, CS2, Fortnite, Valorant & many more
  • Low, Medium, High, and Ultra quality preset predictions
  • DLSS 4, FSR 4, and Ray Tracing performance impact analysis

PC Builder & PSU Calculator

Build Your Gaming PC with Automatic Compatibility & Power Checking

The PC Builder checks the usual pitfalls for you — CPU socket fit, RAM speed support, GPU clearance, and power headroom — so you can focus on picking parts instead of second-guessing compatibility. Pair it with thePSU calculatorto size your power supply with sensible headroom, including transient spikes on modern RTX-class GPUs.

Frequently Asked Questions

Common questions about our PC building and performance tools

How accurate is the FPS calculator?

Our FPS calculator uses publicly available benchmark data to estimate frame rates. Predictions are approximate and can vary based on drivers, game updates, and system configuration. We recommend using the results as a rough guide and cross-checking with actual reviews for your specific hardware.

How does the PC builder check compatibility?

Our PC builder automatically validates CPU/motherboard socket compatibility, RAM speed and DDR generation support, GPU clearance and power requirements, M.2 slot availability, and case form factor matching—all in real-time as you select components.

What PSU wattage do I need for an RTX 5080 or RTX 5090?

For RTX 5080 builds, we recommend 850W minimum with 1000W preferred for high-end CPUs. RTX 5090 builds require 1000W minimum, with 1200W recommended for overclocked systems. Our PSU calculator accounts for transient power spikes up to 550W.

How often is the benchmark data updated?

We update our benchmark database continuously as new hardware releases, driver updates, and game patches affect performance. Major updates occur within 1-2 weeks of new GPU and CPU launches, with game-specific data refreshed monthly.

Can I compare CPUs and GPUs from different generations?

Yes, our GPU comparison and bottleneck calculator support all modern hardware including RTX 50/40/30 series, RX 9000/7000/6000 series, Intel Arc, and CPUs from Intel 14th/13th/12th gen and AMD Ryzen 9000/7000/5000 series.
