Wglgears.exe

The program displays three rotating gears and outputs a Frames Per Second (FPS) count in a terminal window, providing a basic performance metric.

WGLGears.exe is a lightweight OpenGL utility primarily used to test and verify the 3D rendering capabilities of a Windows system. It is a Win32 port of the classic "gears" demo, which has served as a standard benchmark for the OpenGL API for decades. Khronos Forums Core Functionality Performance Benchmarking wglgears.exe

If the animation is stuttering or the FPS is very low (e.g., below 60 on modern hardware), your system may be using software rendering instead of your GPU. Stress Testing The program displays three rotating gears and outputs

If you have ever installed a development environment for graphics programming (e.g., FreeGLUT, GLFW, or even older versions of Borland C++ or Visual Studio with OpenGL samples), wglgears.exe may have been silently placed in your system or project folder. below 60 on modern hardware)
