Umm...no.

The main problem is the memorycap which does limit the amount of media you use. Textures tend to be larger issue than polygons.
FPSC can handle a large amount of polygons very well. It has never been a problem for me. Do you have a version after 1.16 installed?

The pack should support weaker systems just fine. If your computer is really too weak for it I am certain you will have problems with other modelpacks aswell.
Can you play more recent FPSC Games on your system? Like Into the Dark, Leviathan Crossfire, Euthanasia, Thanatophobia?
Quote: "the game slows down"
I can run this with shader effects in very large scenes at a smooth 60 frames. I am afraid it is your system causing the problems as I paid attention to the polycount.
