As for your questions
As far as I know it does work with non Glide vid cards. Actually from the pictures i've seen taken on a non glide machine using glidos it actually looks better than my voodoo card.
As I use a voodoo card I'm unsure about the glidos. But the pictures I just mentioned were taken using the glidos wrapper. They look spectacular.
The sounds are phenominal as are the graphics and more detailed planes on my machine.
