Introduction
This free FPS calculator estimates how many frames per second your PC can run in popular games. Pick a game, enter your CPU and GPU, and get results in seconds. You will see your average FPS, 1% lows, and whether your hardware meets your target frame rate.
The tool also shows which part of your system holds you back the most. Use it alongside our bottleneck calculator to get a complete picture of how your components work together. It compares your setup against other hardware tiers so you can see where you stand. If your FPS is too low, it tells you exactly what to upgrade first and what settings to change for the best performance.
Whether you play competitive shooters like Valorant and CS2 or demanding open-world games like Cyberpunk 2077, this calculator helps you know what to expect before you hit play. Competitive players looking to improve can also track their performance with our KD calculator. Adjust your resolution, graphics preset, ray tracing, and upscaling options to find the sweet spot between looks and smooth gameplay.
How to Use Our FPS Calculator
Enter your game, computer parts, and display settings below. The calculator will estimate your average FPS, 1% low FPS, and 0.1% low FPS so you know how smooth your game will run.
Choose Your Game: Pick the game you want to test. You can search by name, sort the list, or browse the game cards. Click "Check FPS" on the game you want.
CPU: Type your processor name into the search box and select it from the list. This is the brain of your PC and affects how many frames it can push.
GPU: Type your graphics card name and select it from the list. Your GPU matters the most for FPS in almost every game. Make sure your power supply can handle your card by checking our PSU calculator.
Resolution: Pick the resolution of your monitor. Choose from 1080p, 1440p, or 4K. Higher resolutions look sharper but lower your FPS. Not sure about your display specs? Our screen size calculator and PPI calculator can help you understand your monitor's capabilities.
System RAM: Select how much memory your PC has. Most modern games need at least 16 GB for the best results.
Storage Type: Choose HDD, SSD, or NVMe SSD. Faster storage helps reduce stutters and load times, especially in open-world games.
Graphics Quality Preset: Found under Advanced Options. Pick Low, Medium, High, or Ultra. Lower presets give you more FPS. Higher presets make the game look better but cost more frames.
Ray Tracing: Found under Advanced Options. Turn this on or off. Ray tracing adds realistic lighting but takes a big chunk of your FPS away.
Upscaling Technology: Found under Advanced Options. Choose DLSS, FSR, XeSS, or None. Upscaling boosts your FPS by rendering at a lower resolution and then sharpening the image back up. If you want to understand how upscaling changes the effective pixel count, our aspect ratio calculator can help visualize the difference.
Frame Cap: Found under Advanced Options. Set a max frame rate like 60, 120, or 144 FPS, or leave it uncapped. This is useful if you want to match your monitor's refresh rate.
Target FPS Goal: Found under Advanced Options. Set the FPS number you want to hit. The results will tell you if your hardware can reach this goal or not.
Best Settings Toggle: Turn on "Show me the best settings for my hardware" to get a recommendation for the highest quality preset and resolution that still hits your target FPS.
Once everything is set, click Calculate FPS to see your full results, including performance tier, bottleneck analysis, upgrade tips, and hardware comparisons.
What Is FPS and Why Does It Matter?
FPS stands for frames per second. It measures how many images your computer draws on screen each second while you play a game. A higher FPS means the game looks smoother and feels more responsive. A lower FPS makes the game look choppy and harder to play.
In competitive games like Valorant, Counter-Strike 2, or Apex Legends, high FPS gives you a real advantage. You see enemies faster, your aim feels tighter, and your inputs register quicker. Most competitive players aim for at least 144 FPS, while casual players usually target 60 FPS for a smooth experience. If you are serious about PVP, tracking your kill-death ratio with a KD calculator alongside your FPS can help you measure whether hardware upgrades actually improve your gameplay. You can also use our win rate calculator to monitor how your performance changes over time.
What Affects Your FPS?
Your FPS depends on your hardware and your in-game settings. The two biggest factors are your GPU (graphics card) and your CPU (processor). The GPU draws everything you see on screen. The CPU handles game logic, physics, and AI. If one of them is too slow, it creates a bottleneck — meaning the weaker part holds back the stronger one. Our bottleneck calculator can help you identify exactly how much performance you are leaving on the table.
Other things that affect FPS include your RAM, display resolution, graphics quality preset, and whether features like ray tracing are turned on. Playing at 4K resolution or Ultra settings demands much more power than 1080p on Low settings. Upscaling tools like DLSS, FSR, and XeSS can boost your FPS by rendering the game at a lower resolution and then sharpening it back up. If you are also planning your network setup for online gaming, our bandwidth calculator can help you make sure your connection keeps up with your hardware.
What Are 1% and 0.1% Lows?
Average FPS only tells part of the story. 1% low FPS shows the frame rate during the worst 1% of moments in gameplay. 0.1% low FPS captures the very worst stutters. These numbers matter because even if your average is 100 FPS, bad 1% lows mean you will feel sudden freezes and hitches. Smooth gameplay needs both a good average and good lows.
