OpenGL OpenGL: Basic Coding

Is there a way to disable vsync in OpenGL ?

wglSwapIntervalEXT(0);

Beware though, this is an WGL extension. The vsync mechanism is dependent on the windowing system.

If you’re using GLFW, use glfwSwapInterval(0);

Works under Windows and X11 (recent nVidia Linux drivers support VSync selection, finally).
