This is what he has fixed and updated so far. I don't know if it worked for him, so consider what is written. [The new updates were not uploaded here, so anyone who wants/can is welcome to upload them]
Unlock all the progression with the Stepmom and you'll be able to do much more. Now she has all the needed progress for you guys to enjoy your time with her. (and that progression is all done within the chapters to make it more immersive!)
Huge FPS gain!
An increase between 30% up to 80% (Completely depends on the hardware) is noticeable! It can go ever higher, specifically in the scene with only one girls. The main reason for this improvement is switching from "Deferred Rendering" to "Forward Rendering", which is helping a lot in this quest to optimize! It did come at a certain cost at first, but I managed to actually improve the lights and shadows because of that. So it's looking slightly better with more FPS, everyone is winning now
Fixes and Improvements
Fix placement of the Dildo in the room and the easter egg one
Animation pose system with girls now is reset from an animation to another (it wasn't and I didn't realise it since I'm using mostly looping animation)
Added some boundary to prevent going out of the map with the new power
Improve rotation when sitting down (equal reach on each side)
Automatic girl movement now also increase guy pleasure progress bar
Improve transition with automatic sex system (shift+o), now it is smooth when enable and disable
Girl breathing/moaning are blend better when the girl speak (before they were remove, but not all the time, now it should be good)
Sound amplitude of sentence is used to close the mouth when having pleasure (she was talking with the mouth open and felt a little weird)
New light
Destroy cinematic when restarting a chapter
Fix chapter soft locking (it was because of some experimental feature made after the Flamingus update)
Fix stepmom trying to close TV if she isn't in the Life Cycle (unless it's scripted in the chapter)
Readjust light on girl (for the new rendering method)
Fix being stepmom being stuck in chapter "12 Minutes in Heaven"
Added default outfit when starting a chapter (the default is your setup and not an outfit)
Remove quantity objective when a chapter is restart
Added a lightweight Post-Process to create more ambience (like a fog) at need (will be nice in life cycle)
Block sex activity once a girl is using it (otherwise they could overlap)
Fix AI path finding in the stairs (to go downstairs)
Stepmom now have her orgasm bar moving! (I might improve some aspect of this soon (specifically during the life cycle and when I'll integrate the Threesome with the Best friend)
Fix Stepmom flying when going from the character creator back to the "Departure Day" chapter and other chapoter (I added a new variable in the previous state struct so it can know what was the previous collision settings when coming back in the chapters)
Fix dildo not working (apparently hands as well wasn't working, I might have fix both at the same time)
Fix progression icons on the menu (they were not getting refresh without closing the game)
Fix grabbing penis while holding object in your hands
Translation for all language (automatic, will need to be reviewed! Miss a few lines)
Link some sounds effect with the settings
Fix gift giving by Yawn D Big (Native event)
Improve some of the facial emotion with some dialogue in chapter "She want to know"
What's coming next?
Next, the "Life Cycle" is what I'll be fully dedicated to for a few weeks (probably between 8 and 12, maybe more if needed). The goal of the Life Cycle is going to be very simple, to make them have a life! Essentially, that mode is going to have a day/night cycle, a weather system, special events with the girls, the girls are going to move and do activities by themselves, and much more! Once this is completed, it will be time for another chapter, which I can already say is going to include a new character (Stepsis bestfriend in a Threesome).
