Only solution (before getting a better PC), is lowering the graphic settings.
Go and seduce the girls and play the game in lowest setting.... put them higher to H the girls in Free H mode.....
Illusion never bother to really optimize their game, plus tons of mods interacting... yeah, anyone can see the result coming....
I spent 4 hours yesterday well into 5am using the KK manager to export a list of the selected cards, of all the needed mods, becaue I had removed the mods from the game folder.
I then went one by one and found the mods(some were tricky to find since the export list gave me an internal name of the manifest file of the mod, not the name of the zipfile itself) and moved the actually needed mods to "my mods" folder in mods.
I downsized the original 21GB that I was led to believe I needed, to 3.9 GB, along with the other mods, the total is roughly 8 or 9 GB. Now the issue is that there are 4 zip files I have to deal with still. Three zip files are missing, and 1 zip file says is outdated, I thought the betterrepack website was up to date but I guess not(I downloaded some from there cause I was having a hard time finding the mods at times and I got a few from posting the name in the internet and it took me to that site).
What I'm doing now, is that for those 4 mods, just in case I deleted them by accident before or something didn't download right. I'm going to redownload the files from here and then find the mods I need. That one saying that it is out of date is weird cause I don't remember seeing that report in-game the first time.
What I'm missing is:
nashi.Panties.ver1
nashi_ao_inmou <---used the KK Manager to find them, just realized I could use the search bar and it took me directly
roie.WBScarf
and what is apparently out-dated is:
moderchan.AhogeNoShake <--- last thing to fix
EDIT2: got it all to work now, at max settings I can handle 25 people at a time before it hits 100% memory, it was at like 90%(I have 16GB and Windows 11), the FPS, I assume is at 25 or 28, I'll probably lower it to 20 people to get above 30 fps
