Yeah, only an extra gig.
I got lucky, the RAM my PC takes was only about $20 with shipping for 1GB from NewEgg, but I know some people have more expensive RAM than that. I haven't really played around with the HDRI setting at all and I can't take that tS 7 interface, I use the included tS 6 interface (with a few modifications) because it's more like the older versions.
All said and done, I'm not completely warm and fuzzy about the program but you can't beat the price tag. Plus, it has some nice features if you don't mind the fact that it doesn't respond as quickly as the older versions, most of which were designed for Pentium and Pentium II computers running 64 and 128 MB of RAM. (except tS 6, I think it at least requires a Pentium III and 256 RAM)
