Just finished chapter 2 (it was a hecking masterpiece with the music syncs) and no problem with animations.
I tried moving the game from hdd to sdd but it's still laggy during some parts of Noel's h scene.
In chap 1, Amy h scene (handjob street) is fine = good fps. Clara h scene (self peek) is fine, but gets blurry and bit laggy towards the end. Noel h scene (bj dream) is mostly fine but very laggy during bj clockwise rotation, then its fine in POV, then it's fine during bj with hairbun, then it's very laggy during POV of the same scene.
No clue why this is, but meh at least it's not a widespread problem.
Ty for the game and gl for future development !
