Hardware Busters GPU Test Suite
What it is
Hardware Busters GPU Test Suite is a free, open .NET framework for orchestrating GPU benchmarks, preserving measurement provenance, creating reports, and authoring profiles on Windows. It supports profile-driven game launching, navigation, capture, and benchmark orchestration, plus controlled GPU cooler test workflows. Run data can produce self-contained HTML reports. The public source release includes a curated Hardware Busters Verified game pack and disabled community samples. 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 the only capture-card model currently qualified for the full automated game-benchmark workflow. Building is documented with the .NET 9 SDK. The Apache License 2.0 software does not include commercial games, benchmark applications, downloadable content, accounts, or license keys.
For and against
For
- Open-source Apache 2.0 license
- Profile-driven game benchmark orchestration
- Self-contained HTML reports
- Controlled GPU cooler workflows
- Supports custom workloads and 12 presets
Against
- Windows platform only
- Commercial games and tools are not included
- Full workflow requires Elgato Game Capture 4K Pro
- Users must install and license benchmark content
The verdict
Hardware Busters GPU Test Suite provides a structured Windows framework for repeatable GPU and cooler testing, with profile support and portable HTML output. Its hardware qualification and separate game-licensing requirements matter when planning an automated setup.
Who it suits
This suite suits Windows users building repeatable GPU, game, or cooler benchmarks with custom workloads and report generation. Users must supply and legitimately license commercial games and benchmark applications.
