FPS Display: The frame rate is displayed in the window's title bar (e.g., "wglgears - 1452 frames in 5.0 seconds = 290.4 FPS").
Termination: The user closes the window or presses Esc, and the program releases the OpenGL context.
The code is intentionally inefficient by modern standards—it does not use vertex buffer objects (VBOs) or shaders. It relies on the "immediate mode" (glBegin/glEnd), which makes it a pure test of your GPU's legacy OpenGL pipeline.
University courses in computer graphics often provide wglgears.exe to students as a base example of OpenGL animation on Windows.
