will it need a substantially faster PC to run this compared to D:OS 1 ? It run fine on medium settings on my PC, I've already backed the kickstarter and wonder if it will cause a problem.

here is my PC :

DELL XPS 8300
Intel Core(TM) i5-2320 CPU @ 3.00 GHz
8 Go Ram

graphic card is:
AMD Radeon HD 6450

thanks
