Modern graphics processors are designed to handle complex visual workloads across gaming, design, and simulation. To truly understand how your hardware performs under pressure you need more than specifications.
You need a reliable real-time GPU stress test that runs directly on your device.
On this site you run a particle-based GPU stress test: thousands of particles rendered with WebGL2 and simulated with physics (gravity, wind, collisions).
The tool measures how stable your system stays under load and reports FPS, frame time, and performance stability—all in your browser, no installation required.
The test uses WebGL2 particle rendering and physics simulation to load your GPU.
Running it at different particle counts and physics settings gives you a clearer view of how your hardware handles real-time graphics workloads.
Understanding GPU Performance Under Load
A graphics processor does much more than render images. It calculates lighting, geometry, textures, and real-time effects simultaneously. When a GPU is under stress it must maintain consistent frame output while managing heat and power.
Our stress test uses WebGL2 to render thousands of particles with physics simulation—gravity, wind, collisions—creating continuous load similar to gaming and real-time applications.
By observing FPS, frame time, and stability during the test you can see how your hardware performs under pressure and whether it is suited for demanding workloads.
- • Performance clarity — A stress test shows how well your GPU maintains frame stability during continuous rendering.
- • Stability verification — Extended testing helps identify crashes driver issues or graphical glitches.
- • Thermal behavior analysis — As load increases temperature rises. Monitoring this behavior helps ensure proper cooling.
- • Real world performance insights — Testing provides realistic data rather than relying on manufacturer specifications.
- • Running the test at different particle counts and physics complexity levels helps you understand how your system scales under increasing load.
