What is FPS?
FPS refers to the number of frames that a graphics processor (GPU) can render and output per second. It represents the performance of computer hardware (mainly graphics cards and CPUs) in specific tasks (such as gaming).
Testing Methods
Usually specialized software is used to monitor and record FPS in games in real-time, such as Fraps, MSI Afterburner, or built-in FPS display functions in games.
Testing Purpose
Evaluate your computer's performance bottlenecks. High FPS means your computer can quickly generate many frames, making games feel smoother. If your computer has high FPS but low monitor refresh rate, you may not see all frames, causing screen tearing or stuttering.
Monitor Refresh Rate Classification
Entry-level Standard Screens: 60Hz
The most basic screen refresh rate standard
Application Scenarios
- •Most 24-27 inch office monitors under $1000
- •Mainstream home laptops (non-gaming/high-performance models)
- •Standard home TVs (non-premium models) basic refresh rate
Characteristics
Sufficient for daily web browsing, document processing, video watching (most video frame rates are 24/30/60fps, matching 60Hz screens), smooth enough for non-high-speed dynamic scenes, but may show slight motion blur when playing fast-paced games (like FPS, racing games).
Mainstream High Refresh Rate Screens: 75Hz - 144Hz
Advanced smooth experience choice
Application Scenarios
- •Mid-range office/entertainment monitors (focusing on “light smooth experience”)
- •Entry-level gaming monitors (balancing daily use and light gaming)
- •Mid-high-end home TVs, tablets (some 4K TVs come with 120Hz standard)
Characteristics
Compared to 60Hz, less motion blur, smoother web scrolling and window dragging, while adapting to most games' mainstream frame rates (most AAA games can maintain 75-144fps at 1080P quality), balancing “daily use” and “light entertainment”, currently one of the most cost-effective standard screen choices.
Special Purpose Screens: Below 60Hz
Rare special purpose screens
Application Scenarios
- •Some old screens or special purpose screens
- •Early small portable monitors
- •Low-power e-ink screens, some industrial displays
Characteristics
May use 50Hz (mostly early imported equipment adapted to PAL format) or lower refresh rates, but have gradually been replaced by 60Hz, rarely seen in daily consumer markets.
Brand Monitor Refresh Rate Comparison
Different brand monitors have varying FPS (refresh rates). Here are some common brand monitors and their refresh rate specifications:
Sony
ASUS
AOC
HKC
Thunderobot
Koorui
FPS Test Principles & Algorithms
Frame Rate Calculation Principle
FPS (Frames Per Second) is an important metric for measuring device graphics processing capabilities. Our FPS test tool uses advanced algorithms to calculate frame rates through the following method:
FPS = 1000ms / Average Frame Interval (ms)Refresh Rate Detection Algorithm
Monitor refresh rate detection is based on the requestAnimationFrame API, determining the actual refresh rate by analyzing the distribution of frame time intervals:
Refresh Rate = 1000ms / Minimum Frame Interval (ms)Performance Assessment Standards
Test Accuracy Optimization
Uses sliding window algorithm to calculate the average of the last 100 frames in real-time, ensuring accurate and stable test results. Also uses WebGL technology to simulate real gaming scenarios, providing test results closer to actual usage experience.
FPS Test Applications
Gaming Performance Testing
Test actual frame rate performance during game operation, evaluate whether devices meet game requirements, help users optimize game settings and hardware configuration.
Monitor Refresh Rate Detection
Accurately detect the actual refresh rate of monitors, verify if they reach the nominal value, help users understand the real performance of display devices.
Hardware Performance Evaluation
Evaluate GPU and overall system performance through FPS testing, provide data support for hardware upgrades and system optimization, help users make informed purchasing decisions.
FPS Test Examples
| Device Type | Typical FPS Range | Refresh Rate | Performance Rating | Use Cases |
|---|---|---|---|---|
| High-end Gaming PC | 120-240 FPS | 144-240Hz | Excellent | Competitive Gaming, VR Applications |
| Mid-range Gaming PC | 60-120 FPS | 60-144Hz | Good | Mainstream Gaming, Design Work |
| Entry-level PC | 30-60 FPS | 60Hz | Fair | Casual Gaming, Office Applications |
| Mobile Devices | 30-90 FPS | 60-120Hz | Variable | Mobile Gaming, Daily Use |

FPS Test FAQ
Why are my FPS test results unstable?
FPS test results may be affected by various factors including background programs, system load, temperature control, etc. It is recommended to close unnecessary programs and ensure the system is in a stable state for testing.
How to improve FPS test accuracy?
To improve FPS test accuracy, it is recommended to update graphics drivers before testing, turn off vertical sync, ensure monitor refresh rate is set correctly, and test in a stable network environment.
What is the relationship between FPS testing and actual game performance?
FPS test results reflect the device's graphics processing capabilities, but actual game performance is also affected by CPU, memory, storage devices, and other factors. It is recommended to evaluate comprehensively with other performance indicators.
How does monitor refresh rate affect FPS testing?
Monitor refresh rate determines the maximum frequency of screen updates. Even if FPS is high, if it exceeds the monitor refresh rate, users cannot perceive higher smoothness. It is recommended to match FPS with refresh rate.
