Despite their claims about "true 4K" and thus not competing with the pro, they're using the same techniques.
The Assassin's Creed Origins director confirms here that the game will be dynamic 4k on XB1X: https://www.youtube.com/watch?v=FtllzLCt1WY
Edit: there seems to be some confusion. Yes, this is old news for some but clearly new to others going by posts in this thread. Also, this thread is a reaction to Spencer's comments from recent interviews, as explained here:
For the record, I don't think there's anything wrong with checkerboarding or even dynamic 4K. I think they're fine techniques. I also think a "native 4k mandate for all games" would be a bad idea anyway.

I think the issue comes from Phil spinning the BS about how the Pro isn't in competition with the X as it's not got the power for True (Native) 4K when we all know full well it does and has done so on various games. Same situation applies over both machines, developers choose how they use the power available. There is no doubting the XBX is the more powerful of the two machines, but the crap Phil spouts about it not being true 4K surely then applies to his own machine if it's using other techniques to get there sometimes?
For the record, I don't think there's anything wrong with checkerboarding or even dynamic 4K. I think they're fine techniques. I also think a "native 4k mandate for all games" would be a bad idea anyway.
