Why aren't graphics done as vectors?

[dwp9296]

As many people have said already vector graphics would not be practical for textures in 3D games.

That said I don't understand why vector graphics aren't used as widely for user interfaces especially in PC games. It doesn't require that much more power and would scale to any resolution.

There's alot of hurdles to doing this. Flash based games with simple graphics DO use them. But artists are slowly finding ways around the problem of not being able to comfortably draw/paint/sculpt their work.

But as has been said the files get extremely large.
