My point was, saying a console won't be able to do something because a PC of similar spec can't is pointless due to better optimisation of the hardware for a console game compared to said PC of similar spec.
There won't be massive optimisations to be had from the off. Later down the line sure but my assumption already added a flat % (for ease) for the removal of Windows / DirectX and the allowance of low level access on consoles. It's a guesstimate at this stage of course but it's useful to gain an idea.
