When a developer was asked if he felt PS4+GLNext, or X1+DX12 would come out on top. Brad Wardell responded that he would pick the Xbox One. Brad is currently working with both GLNext & DirectX 12 and is scheduled to deliver talks on each at GDC 2015.
Brad seems to be quite impressed with DX12.i think his studio will be showing off their DX12 engine at GDC. I just hope devs(1st and 3rd party) working on upcoming games decide to use DX12 as the standard on Xbox One also whatever surprises MS has planned for GDC must be good..been hearing some good things..cant wait.
im sorry that guy is full of crap , he stated in an interview that the ps4 has better hardware , now he says dx12 with x1 will be better. lol. he is like mister x.
