If this is a "plug-in" as stated on W & S website, I'm assuming that you could continue to run the standard programme on an old machine, but elect to load the "plug-in" onto an up to date unit. The reason I ask is that until last week I had 2 useable computers, an Evesham using XP3 and a Mesh which I loaded Windows 7 into and struggled as it kept shutting the USB ports down. The psu then failed in spectacular fashion and the surge has wrecked most of the internals! I now have a unit equipped with an Intel i-5 Quadcore plus 4GB RAM, and a Radeon graphics card which has 1GB memory on the way!
I would have guessed that although this is a mediocre machine by today's standards, it should run the 3D add-on without too much trouble?
Tarbat will probably know the answer to this one.
Thanks
