Bugs:

The mouse prompts are not where they are supposed to be, they are slightly offset. [FIXED]

The pre-rendered cutscenes are stretched. The in-game ones are not.

Some resolutions have a black bar on the side when in Dual Reality. [FIXED]

FOV Adjustment:

You can use this tool Link [framedsc.github.io] to raise your FOV by unlocking the UE4 console, pressing ~ and typing “fov xx” to your desired FOV.

1. Go to configs location

2. Open Engine.ini

3. Add the following line

[/script/engine.localplayer]
AspectRatioAxisConstraint=AspectRatio_MaintainYFOV

4. Save

EDIT:

To fix the button prompts and dual reality black bar:

1. Replace 39 8E E3 3F hex value with 8E E3 18 40 the same way you replaced the other ones above.

2. Save

Since the gamepass version is pretty locked tight, you can use this trainer that does the same thing but works on the gamepass version as well as an alternative:
