FurMark 1.39.4

FurMark: GPU Stress Test and Graphics Benchmark

FurMark, developed and maintained by Geeks3D, is a free GPU stress-testing and benchmarking utility for Windows and Linux. Designed to generate extreme OpenGL and Vulkan workloads, FurMark stresses graphics cards to reveal thermal limits, stability issues, and rendering artifacts that lighter tests may not expose. The tool serves as both a burn-in utility and a quick graphics benchmark with online score submission for comparative analysis.

Key Developments

• FurMark 2: Successor to the original release, offering improved Vulkan and OpenGL support, expanded command-line options, and native 32-bit and 64-bit builds for Windows and Linux. Built with GeeXLab and intended for modern systems and workloads.
• Legacy FurMark 1: Continued maintenance of the original FurMark 1 for compatibility with older 32-bit Windows environments and workflows that require the legacy build.
• Online Score Integration: Benchmark results can be compared against online leaderboards such as GPUMagick and gpuscore portals to evaluate relative performance across systems and drivers.
• Ongoing Resources: Downloads, changelogs, command-line documentation, and community support are available via Geeks3D resources, forums, and Discord.

Features and Functionality

• High-intensity workloads: Render patterns that create sustained, high GPU load aimed at exposing thermal throttling, unstable overclocks, and hardware faults.
• OpenGL and Vulkan benchmarks: Dual-API testing allows comparison of driver and API behavior under stress and provides quick benchmark scores for cross-system comparison.
• Cross-platform binaries: Native builds for Windows and Linux in both 32-bit and 64-bit formats, covering modern and legacy setups.
• Command-line support: Enhanced CLI options enable automated, unattended runs suitable for test rigs and integration into validation pipelines.
• Adjustable parameters: Control resolution, MSAA, duration, and workload settings to tailor tests to specific validation goals.
• Compact interface: A minimal, utilitarian UI emphasizes repeatability and clear test conditions rather than extensive visualization or telemetry.

Practical Applications

FurMark targets worst-case thermal and power scenarios rather than everyday gaming loads, making it useful for validating cooling solutions, detecting unstable overclocks, and reproducing driver regressions. It complements real-world game tests and other synthetic benchmarks by focusing on sustained, extreme GPU utilization.

Intended Users

• Overclockers: Verify stability after tuning clocks, voltages, and fan profiles.
• System builders and OEMs: Exercise GPU cooling and system thermal design under prolonged load.
• Enthusiasts and gamers: Confirm that a GPU operates within expected thermal and stability limits under heavy sustained stress.
• QA and benchmarking professionals: Use command-line automation and online score comparison for reproducible test data and regression detection.

Getting Started

1. Download the appropriate FurMark build from the Geeks3D downloads page for Windows or Linux.
2. Choose FurMark 2 for modern Vulkan/OpenGL testing or FurMark 1 for legacy 32-bit Windows environments.
3. Configure resolution, anti-aliasing, and test duration; use command-line options for scripted or unattended runs.
4. Monitor system telemetry alongside the run to correlate temperatures, clocks, and any rendering artifacts.

Support and Resources

Official downloads, changelogs, a gallery, and command-line documentation are hosted on the Geeks3D site. Community support and discussion are available through Geeks3D forums and an official Discord channel maintained by Geeks3D.
