CDPR will hopefully backtrack a little and release a PC upgrade patch, if the sole reason for the downgrade is due to developing for the lowest common denominator (XBONE) then surely they could easily get much better results out of the PS4 and PC.
Well, less said about this possible reason the better TBH.
I think you might see a high res texture pack pop up just as it did for games like Crysis 2 and sleeping dogs etc... But I wouldn't hold your breath.
I did find the whole dynamic resolution for X1 a total joke TBH (and I know this'll upset folks) but really? If the machine can't do solid 1080 then thats just how it is, thing is PC is a different beast as users can themselves decide if they want framerates over resolution or settle for higher textures at 1080 with 30fps cap (using nvida inspector to radeon pro to cap the fps etc..
Consoles, well they are what they are, X1 is the weakest link then no game should be created on it when its across other platforms, its the weaker so no other gamer should suffer due to it. Its that simple, regardless if you agree or not.
PS4 isn't that much stronger the X1 truth told, its got a bit more grunt, but PC has way more power if you have purchased some top end kit.
Its annoying if this statement is true but wait and see I guess. I'm half on the fence to buy this for PS4 or PC myself. I'm not sure how my 7970M will cope with it, but then if is been created to work on X1 then my 7970M should be just fine in this regards : - )
