FurMark vs stress-ng

FurMark is a free Windows application for GPU stress testing and graphics benchmarking. It applies a sustained 3D workload to examine thermals, cooling headroom, power limits, and overclock stability. OpenGL and Vulkan rendering paths are available where supported. Benchmark choices include 1080p, 1440p, and 4K presets, along with timed passes. Artifact-oriented checks help identify visual problems such as sparkling or corrupted textures, which may point to heat, memory strain, or unstable tuning. For sensor context, FurMark recommends pairing runs with vendor tools or overlays, including GPU-Z and HWiNFO. Downloads come as an installer or a portable edition that runs from a folder or USB stick without installation. It is aimed at overclockers, PC gamers and builders, reviewers, benchmarkers, and support technicians. The FAQ points to a forum for troubleshooting. Tests should be supervised, temperatures watched, and unsafe runs stopped. The listed plan costs nothing for personal testing on Windows 10/11.
