As you say, English is not my native language and I accept and I apologize if sometimes I may not be expressing myself with due clarity.
That said, there are several posts where I have wanted to define my opinion and feelings and I think they are clear and logical.
It is as simple as that, after that article on Xbox Wire, my feeling that TC's help was essential for the Matrix demo to work decently in XSeries and especially in XSS and that for the PS5 version, Epic did not need so much the direct support of a Sony studio because they are already more than accommodated to their hardware and tools.
Without this TC optimization work, the small Epic team would have suffered to achieve the result that is seen today and who knows if they had considered making only a single PS5 version.
Their experience developing on PS5 is objetively greater and they know their tools better because they even created a specific technical demo. In XSeries his experience is ""nil"" and that is where TC came in, to alleviate that experience deficit with XSeries hardware.
I have never mentioned things like using different mods of the UE5 for each console
.
To sumarice, I am referring to the advantage in terms of optimization of the simple experience of having worked with hardware (PS5) for several years (even in its design process) compared to not having (XS). Add that it is an engine in development and that there are still 1000 things to adjust before going to the market and you have the logic that TC was essential for this Matrix demo to be launched in XSeries, more so in this very premature state of UE5. (especially in XSS)
