WebGPUStress is a browser-based GPU stress testing tool that uses WebGL to push your graphics card under sustained load. It helps detect overclock instability, thermal throttling, and performance decay without requiring any installation or plugins. Key features include:
- Configurable test duration (1-15 minutes), resolution (720p to 1440p), quality (Medium to Ultra), and target FPS (30 or 60).
- Real-time metrics: Average FPS, 1% Low FPS, Frame Time Stability, Drop Frame Ratio, and a Stability Score (0-100).
- Quick presets for health checks, thermal soak, and FPS drop analysis.
- Detailed result interpretation guides and a decision matrix for classifying GPU behavior.
- Works on desktop and mobile browsers (Chrome, Edge, Firefox, Safari).
- No direct temperature readout; recommended to pair with MSI Afterburner or GPU-Z for telemetry.
Use cases: after overclocking, laptop thermal checks, gaming stutter diagnosis, VM acceleration validation, new PC build verification, and cooling upgrade comparisons.
