About This Tool
This GPU stress testing tool is designed to push your graphics card to its limits, helping you evaluate its performance, stability, and thermal characteristics under heavy workloads. Whether you're testing a new GPU, checking for overclocking stability, or just curious about your system's capabilities, this tool provides comprehensive testing modes.
What Does It Do?
The tool runs intensive WebGL shaders that stress different aspects of your GPU:
- Compute Operations: Heavy mathematical calculations including fractals, noise generation, and complex algorithms
- Memory Bandwidth: Intensive texture sampling and memory access patterns
- Geometry Processing: Rendering hundreds of dynamic shapes with complex transformations
- Shader Complexity: Multi-layered fragment shaders with branching and loops
How to Use
- Check Your GPU Info: The tool automatically detects your graphics card and displays its capabilities
- Choose Test Settings: Select duration (5-120 seconds), test mode, intensity level, and resolution
- Start the Test: Click "Start Test" and watch your GPU work hard
- Monitor Performance: Keep an eye on FPS, frame times, and the real-time performance chart
- Review Results: Check average, minimum, and maximum FPS after the test completes
Test Modes Explained
- Compute Intensive Enhanced: Heavy mathematical operations, fractals, and complex shader calculations
- Memory Bandwidth Test: Intensive texture sampling to stress memory subsystem
- Geometry Rendering Test: Hundreds of dynamic shapes to test geometry processing
- Comprehensive Stress Test: Combines all test types for maximum GPU utilization
Important Safety Notes
- Temperature Monitoring: Keep an eye on GPU temperatures. Most modern cards throttle around 83°C
- Power Supply: Make sure your PSU can handle peak GPU power draw
- Cooling: Ensure adequate case ventilation and GPU cooling before testing
- Duration Limits: Don't run extreme tests for more than a few minutes at a time
- System Stability: If you experience crashes or artifacts, reduce intensity or stop testing
Understanding the Results
FPS (Frames Per Second): Higher is generally better, but consistency matters more than peak performance. Look for stable frame rates without big drops.
Frame Time: The time it takes to render each frame in milliseconds. Lower is better. Spikes indicate potential issues.
Performance Chart: Shows how your GPU performs over time. Thermal throttling will show as gradual FPS decline.
Troubleshooting
- Low FPS: This is expected under stress testing. If it's extremely low, check if your GPU drivers are up to date
- Browser Crashes: Reduce intensity level or resolution. Some browsers limit WebGL memory usage
- Blank Screen: Your GPU might not support the required WebGL features. Check the GPU info section
- System Instability: Stop the test immediately and check your cooling and power supply
Technical Details
This tool uses WebGL 2.0 (falling back to WebGL 1.0) to create GPU-intensive workloads entirely within your browser. It doesn't install anything on your system and runs in a sandboxed environment. The stress tests use fragment shaders with high computational complexity, multiple texture samples, and intensive mathematical operations to maximize GPU utilization.
Note: Results may vary between different browsers and systems. For the most accurate stress testing, consider using dedicated GPU stress testing software like FurMark or Unigine Heaven alongside this web-based tool.
