Vector Programs

Are all vector programs known for being sluggish? My computer is getting old (1.5ghz) now but as I have never done any vector work before so I`m not sure if this is normal. Normal paint programs like Photoshop work fine however but I want a dedicated vector program.

I`m using InkScape and it is really slow here.

If it is a CPU thing are there any other free alternatives out there that are a little nippier\computer friendly?

Also, one last thing, are there any programs around that allow you to vary the thickness of a line via a graphics tablet according to pressure? I assume the expensive ones do this but what about the free ones?

Thanks for any help,
Jason.

I don't know about speed issues. I used Inkscape a bit on an old 1.2Ghz Athlon and thought is was OK (on and old ATI card).

I'm sure, though, that I got Inkscape itself to recognise the pressure sensitivity on my Trust Tablet. I can't remember the option, but I'm sure there's a way to do it.

Nope, get a new computer.

Aha so are you experimenting with vector art instead of pixelated art? I was interested in that too as it's a way to get good looking sprites that are suitable for modern games.
