Correct, Bea.. which is why I include both.. since changing a line of code twice to make it usable by a ton more people is an easy thing to do.  They won't be usable by people who can't run 3.* and don't own HSS though.. need regular basic DS 2 mats for that... which I also make if it's a commercial product.

Now.. that being said, you can get very nice results out of the basic surface tab and they render really fast. SS is bloody slow.

Which texture are you trying to make mats for and where is it living right now?
