I mean, that's the point of Dune? The 'prophesies' aren't real, they're seeded by the Bene Gesserit, the same group that spent millennia breeding the 'savior'. And, he's not meant to really be a savior, but their catspaw.
But also, he's definitely not actually a savior, on account of all the death he brings. It's complicated, but overall a deconstruction of white savior narratives and similar stories.
I'm talking about the stuttering, caused primarily not recalculating shaders. Something I just dealt with the entirety of my first playthrough of ER. But the fact that it still isn't fixed really makes me not want to play, or to pay them money.
