Now where you using the trans pack im talking about? Or a program? Because all the transpack does is replace a couple .DLL files adding the themse to your list of options and changes some fonts and stuff. So in no way really can it take up anymore resources than your regular luna theme.
EDIT: Aye the gf got ahold of the internet drive!!! (BTW using Vista Transformation pack 4.0)
