[solved]XBOX 360: WHY wasn't it x86?[NEW QUESTION]How hard would it be for MS to emulate/go BC with original Xbox games?

[Zappykins]

A difference kind of question.

Since DirectX, at least on the PC, is always backwards compatible, with limitations on some things being stuck at DX 9C, it would seem to me not impossible for Microsoft to make Xbox One somewhat backwards compatible. (Where certain games run like the Xbox 360/Xbox Original.) So it looks like they could if they really wanted too.

I think they dropped all the backwards compatibly stuff on the Xbox One so it would be easier to optimize. I got that from a talk from Mark Whitten. There was a big break between DirectX 10 and everything before it as far as how it does things- which can cause computability issues. Xbox One used DirectX 11.2 - which is a mature refined version of the lasted DirecX set.

In addition to the hardware differences, the way the Xbox One's DirectX does things is also different. So perhaps with all these changes they just decided it wasn't worth it? (Plus that 100 million cost on the controller - doubt there was too much 'back wards compatible' budget left over.)
