Frames per second printing + + GLUT now looks for an environment variable called "GLUT_FPS". If it's + set, GLUT will print out a frames/second statistic to stderr when + glutSwapBuffers() is called. By default, frames/second is computed + and displayed once every 5 seconds. You can specify a different + interval (in milliseconds) when you set the env var. For example + 'export GLUT_FPS=1000' or 'setenv GLUT_FPS 1000' will set the interval + to one second. + + NOTE: the demo or application must call the glutInit() function for + this to work.
