Still cannot get the game to run properly in 3840x2160--rather, it's the diary portion of the inventory option that refuses to align properly at that resolution--it's unreadable. So am playing @ 1920x1080--which is not bad but not ideal. Wish they'd fix this. Otherwise, the game runs fine.

OK, using this updated patch:

I can at least run the game @ 2560x1440 without losing the diary notes! Definite progress...;)

How it looks @ 3840x2160:
