In real down to earth practical terms it means that boned animations aren't as fast as they could be (on newer hardware), normal mapping isn't as fast as it could be (on newer hardware), shadows aren't as fast as they could be (on...). Water, glass, grass, particle, smoke, haze, fog effects aren't as fast as they could be (on...) etc.
But, it also means anything you write in Blitz3D will run on almost any hardware. Which is a big plus point.
