My PC is just a fairly basic Acer laptop, with an i5 intel core and 8 gigs of ram. It's not like a gaming PC or anything, but it fits my needs. I usually get 30-40 FPS on really detailed and big saves.
I am running:
Intel(R) Core(TM) i7-4700HQ CPU @ 2.40GHz
GeForce GTX 860M
12GB 1600mhz RAM
I get:
0fps on menus, -5fps on saves.
