So smooth. I've never played a Souls game that had a smooth framerate before.
You're in for a treat. I've played all Souls games on PS3 and then PC. (except for Demon's, of course)
I always prefer playing the PC version due to the stable framerate as well as the potential for graphical mods or tweaks.
EDIT: OH, and the loading times, obviously! Insane difference on PC even back before I used SSD.
