    FurMark

    FurMark

    GPU stress test OpenGL and Vulkan graphics benchmark Windows/Linux

    FurMark is an intensive benchmarking tool designed to evaluate the performance of graphics cards using fur rendering algorithms. This tool is particularly effective in generating high workloads that can significantly increase the temperature of the GPU, making it a useful utility for testing the stability and stress tolerance of graphics cards. By simulating demanding rendering tasks, FurMark serves as a comprehensive test for assessing the robustness and thermal performance of GPUs under extreme conditions. FurMark from Geeks3D is a free OpenGL benchmark tool for Windows that can also be used to check the stability of a graphics card thanks to a built-in stress test. FurMark rendering is designed to overheat the GPU making it a viral-like stability and stress test tool (also called GPU burner) for the graphics card.
