GPU Torture Test Stress
Eight stacked full-screen raymarching passes per frame, so even a fast GPU cannot simply sit at its refresh rate. Heavy: read the warning first.

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
Stacks eight full-screen raymarching passes per frame so even a fast GPU cannot simply sit at its refresh rate. It is a heavy load meant to find the limits of cooling and power delivery.
It needs an acknowledgement before it starts and has an always-visible Stop button. A browser cannot read temperatures, so watch them with a monitoring tool. It does not prove long-term stability.
How to read the results
Watch the average FPS for how much work the GPU finished, and the 1% and 0.1% lows for stutter. The SMG Verdict after the run scores power, steadiness, endurance, pacing and spike control from 0 to 100 and gives a tier from S to D. The class score removes intensity and resolution so runs at different settings share one scale; about 2,000 is a steady 60 FPS.
Because the load is not capped by the display, the score is not tied to your refresh rate. Compare Torture runs only with other Torture runs.
Frequently asked questions
Is the torture test dangerous?
It is demanding but within what a healthy GPU is designed to run. Keep an eye on temperatures, make sure cooling is working and stop if you see artefacts or the system becomes unstable.
Why does the screen look choppy?
That is expected. The load is designed to push frame rates down so you can see the GPU's limit.
When should I use it?
After overclocking, a repaste or a cooling change, when you want to see how the system behaves under a heavier load than a normal game.
What does a failure mean?
A crash, a black screen or artefacts under this load suggests instability. Reduce overclocks or check cooling and power.
