Crackdown 3 was running Native 4K and Microsoft confirmed that all of their games will run native 4K on the Xbox One X.

I believe Digital foundry more this time, they wouldnt have said it this way for Forza if that would be the case. They pixel count every trailer.

The crackdown devoloper said true 4K like every game was called this way in MSs E3 press conference
