About
WebGPU Stress is a free browser-based GPU stress testing and graphics performance tool.
It runs sustained graphics workloads directly in the browser and tracks average FPS, 1% low FPS, frame-time stability, dropped frames, and overall performance stability.
The tool is useful for quick GPU stability checks, comparing performance before and after graphics driver updates, testing laptop performance under sustained load, and identifying FPS degradation during longer runs.
No account, download, plugin, or desktop software is required.
WebGPU Stress is designed as a lightweight first diagnostic step. Browsers cannot access detailed GPU temperature, clock, voltage, or power telemetry, so it complements rather than replaces native tools such as FurMark or GPU-Z.
