Endurance Test Stress
A 15-minute sustained run with the 3D scene. The verdict charts performance over time so you can see whether it settles or keeps falling as the GPU heats up.

Before you start
GPU stress tests can significantly increase GPU load, temperature, power draw and fan speed.
Stop the test if your system becomes unstable, overheats, crashes or behaves unexpectedly. Do not run extreme tests on hardware with known cooling problems. This website cannot guarantee hardware safety.
This is a deliberately punishing test. It can push your GPU to its thermal and power limits for minutes.
- Laptops: plug in the charger and make sure the vents are clear.
- Make sure your GPU is cooled properly. Do not run this with known fan or cooling problems.
- Save your work and close other important tabs. A weak or overheated GPU can make the screen flicker or the graphics driver reset, which may close apps.
- You can stop at any time with the Stop button or the Escape key. The test also stops itself if frames take more than two seconds.
Long run: this test keeps the GPU busy for five minutes or more, so your computer will get warm. Laptops should be plugged in. You can stop at any time with the Stop button.

About this test
A 15-minute sustained run with the 3D scene. It charts performance over time so you can see whether the GPU settles at a steady level or keeps falling as it heats up. It is the longest of the standard tests.
It does not read temperatures and cannot say why performance changes, only that it did.
How to read the results
Read the performance-over-time chart first. A line that flattens after the first few minutes means a stable operating point. A line that keeps falling points to heat or power limits. The Endurance axis summarises the change; the first slice of the run is skipped because shader compilation and clock ramp-up distort it.
Frequently asked questions
Why fifteen minutes?
Cooling systems take several minutes to reach a steady state, so a long run shows where performance really settles.
Can I stop early?
Yes, but the verdict needs enough data to compare the start and end, so very short runs give less reliable results.
Should I use a laptop on battery?
No. Plug it in and select the high-performance mode, otherwise power limits will dominate the result.
What if my score rises over time?
A small rise can come from clocks and caches warming up. A large rise is unusual; check that nothing else was using the GPU at the start.
