I do use it with Carrara but mainly I use it for 3DSmax and Lightwave. I bought Carrara because I can model much faster with it than I can with my primary solutions. It works VERY WELL with Carrara but again I am running NT40 and I have yet to see Carrara ran under Win98 although many people do run it under 98, I have never seen it personnally so I cannot comment on it. But Yes the VX1 runs very well with Carrara and very fast also. So if you Carrara is one of your motivations for purchasing the card, oh then by all means go for it. VX1 + Carrara = A very happy user!
