Valve's gpuvis turns messy GPU traces into a visual timeline

gpuvis: GPU Trace Visualizer

gpuvis is an MIT-licensed GPU trace visualizer originally built at Valve Software, now with 914 stars on GitHub. It renders Linux perf, Intel i915 and Xe driver traces, and Windows ETL captures as an interactive timeline, with support for Linux perf JSON export and WASD navigation. Built in C++ with Dear ImGui and SDL, it's a practical tool for anyone hunting frame-time spikes and driver bottlenecks.
