Hardware Busters GPU Test Suite vs PerfDog

Hardware Busters GPU Test Suite is free, open-source Windows software for orchestrating GPU benchmarks, preserving measurement provenance, producing reports, and authoring profiles. It can launch games through profiles, navigate them, capture output, and coordinate benchmark runs. Controlled GPU cooler workflows add measurement and reporting support. Run data becomes self-contained HTML reports. The public source release includes a curated Hardware Busters Verified game pack and disabled community samples, with custom workloads and 12 benchmark presets. Documented workflows use PresentMon or RTSS for FPS and frametime evidence, while FFmpeg and an Elgato capture stream support OCR, navigation, and motion tasks. Elgato Game Capture 4K Pro is currently the only capture-card model qualified for the full automated game-benchmark workflow. Building is documented on Windows with the .NET 9 SDK. The Apache License, Version 2.0 covers the software. Commercial games, benchmark applications, downloadable content, accounts, and license keys are not included; users must install them and hold legitimate access. A documented pre-flight performs a bounded stream probe and says no image is retained. Bugs and security issues go through the repository issue tracker.

PerfDog is a performance testing and analysis tool for applications and games, with real-time views of FPS, CPU, GPU, memory, frame time, and jank. Its listed platforms include Android, iOS, macOS, web, and Windows, with support also listed for Switch, PlayStation, and Xbox. PerfDog says tests need no root access or jailbreak, require no app changes, and add less than 1% overhead. It claims FPS precision of ±0.1, timestamps at 1 ms, and a 1000 Hz sample rate. AI-driven reports and bottleneck detection include one-click analysis of a single report. PerfDog CLI plus Service supports remote testing and CI/CD integration. Its cloud dashboard stores and manages test cases and supports team tasks and sharing. PerfDog MCP offers 15 tool interfaces, and its site shows workflow results being sent to WeCom and Lark. The free version is for non-profit organizations; research users can apply for a charity quota. Pricing for other use is available on request.
