What We Test and How to Interpret Results
Our GPU stress test uses WebGL2 particle rendering and physics simulation to push your graphics hardware in real time. Measure FPS stability, frame time, and performance under load—no installation required.
Run Stress TestWhat We Measure
We run a high-intensity particle system test in your browser. The test uses WebGL2 to render thousands of particles with physics simulation—gravity, wind, collisions—to create continuous GPU load. We track frames per second (FPS), frame time in milliseconds, active particle count, and performance stability over time.
Results help you see how well your GPU handles real-time graphics workloads similar to gaming, design tools, and simulation. You can adjust particle count (1,000–10,000) and physics complexity (simple, medium, complex) to scale the stress level.
How to Read Your Results
Average FPS and minimum FPS show how consistent your GPU is under load. Frame time variance indicates stability. Lower variance means smoother performance. Performance stability is a combined metric that reflects how well your system maintains throughput during the test.
Use the export option to save results for comparison after driver updates, hardware changes, or cooling improvements. Many users run the test multiple times with the same settings to confirm consistency.
Limitations
This is a browser-based tool. Results depend on your browser, operating system, drivers, and background apps. We do not collect or store your benchmark data; everything runs on your device.
The test is intended for comparative analysis and stability checks, not as a replacement for professional benchmarking suites. For the most reliable read, close other heavy applications, ensure good cooling, and run the test when the system is idle.
