Yes I know this. T
he reason why I havn't mentioned this is becouse we were discusing perofrmance. And if you go and benchmark Grphic card performance when it is only using its internal Graphic memory or when using Extended graphic memory (some data may be loaded in RAM) you will clearly see performance diferences. The rason for this is the fact that Graphic card can read information from its internal graphic memory much faster than reading this information from RAM especially if some other part of your application is heavily utilizin RAM for some other things.
