even if there is a difference it probably just is a slight change in performance

The difference is in performance. OpenGL uses the video board's full capabilities, while DirectX uses software-based kludges to emulate similar capabilities. In other words, OpenGL places the image processing load on the card. while DirectX places the load on the processor, thus the performance hit.

The Schutzstaffel (German for "Protective Squadron"), abbreviated SS, grew from a small paramilitary unit to an elite force that served as the Führer's "Praetorian Guard," the Nazi Party's "Shield Squadron" and a force with as much political influence as the regular German armed forces. Built upon the Nazi racial ideology, the SS, under Heinrich Himmler's command, was primarily responsible for the crimes against humanity perpetrated by the Nazis during the Second World War.

"We cannot continue to rely only on our military in order to achieve the national security objectives that we've set. We've got to have a civilian national security force that's just as powerful, just as strong, just as well-funded." Barack Obama - 10/30/2008
