The choices are around act 19 to 41 out of more than 200 acts. You can select what you want, there is not much difference. After act 41 your choices have no effect at all and you can "skip unseen content" with CTRL-key until you reach current content. That's maybe 1-2 minutes holding down a key. The story is linear and very short with only 21k lines of script compared to some other games.
If you right-click in the game (eg to Save / Load), you can access the Story Map screen (top center) which allows to directly select every single act of the more than 200 acts. V0.48 started with act 196.
For the special renders check the OP. There is a key combination to unlock all renders mentioned but I cannot say if it still works in current version.
If you are too lazy, you can unlock all images by pressing "ALT + SHIFT + U" when you are on the hidden gallery screen.
You can also directly find the special renders in path : GuiltyPleasure-0.51-pc\game\images\HG
Note :
If you want to enjoy the story, you should start a new game and go through the whole story again ... updates are short and lack variety so that the game feels worse than it actually is.
