star98 Monday, November 24, 2025I built a free tool called Volume Shader. It's a web-based GPU performance testing tool that combines benchmarking with real-time 3D volume rendering visualization.
You can use it to stress test your graphics card and get performance metrics like FPS, frame times, and GPU utilization, all directly in your browser without needing any installation. It's cross-platform and works on any system with a WebGL-compatible browser.
