OGL EXTRA HOOKS

OGL_EXTRA_HOOKS was first introduced with Xfire ingame since the beginning of Xfire ingame supporting OGL. It was added to every game using OGL... I'm guessing they just eventually incorporated it into OGL coding cause every current game support update has never included this flag so it can be pretty much deemed obsolete. If coding though and you can't get a game to work with OGL? You can try this just in case but I doubt it will bring you much luck.
