Patch 1.06 on Xbox One X significantly increased the resolution during cutscenes that are now capped to 30fps. A scene that rendered at approximately 1440x2160 on 1.04 now renders at approximately 3000x2160 on 1.06. These cutscenes still use a dynamic resolution that can reach native 3840x2160 and still seems to use the same temporal reconstruction technique as before.
The 30(ish) fps capped cutscenes also happens on Playstation patch 1.06 too. Still horrible framepacing issues. I don't see why they think this was needed.

Note that the base PS4 has also had the same cutscene frame rate cap applied to it and it also exhibits frame pacing issues. Patch 1.06 on PS4 Pro significantly increased the resolution during cutscenes that are now capped to 30fps. A scene that rendered at approximately 960x2160 on 1.04 now renders at approximately 2048x2160 on 1.06. These cutscenes still use a dynamic resolution and still seem to use the same temporal reconstruction technique as before.
