SFML contains support for OpenGL inside of it, I would not be surprised if you were manually including OpenGL files into your project that conflicted with SFML, if you are not, then check that you have the max frame rate set low enough so that OpenGL dosn't flood your processor, if that is not it, check that your are calling sf::Window.Display() and glClear(GL_COLOR_BUFFER_BIT | GL_DEPTH_BUFFER_BIT); to first of all, display the screen, and second, to clear the buffer, or else OpenGL will be overwriting what was already written, if you did that correctly, and its still wrong, Email me at WeeveFerrelaine@yahoo.com, and I will Email you back with my project that currently implements OpenGL in SFML.
