To be honest, despite asking everywhere, there's no confirmation (from Warhorse that I can find) that KCD will be optimized to run on modern typical gaming PC at 60 fps. And by typical I mean i-5/i-7 with around 8GB ram and GTX 9xx or 1xxx card on 1920x1080. Anything under that would be a deal-breaker for me for sure.
Sure, Cryengine might be demanding, but all this wait is for nothing if final product is anywhere like the beautiful, yet horribly, horribly slow slideshow that beta was.
I guess lack of clarity on this, very, very important question is coming back to bite devs in the arse in the form of threads like this.
