Hello zale, koikatsu party and chara studio are two differents things, but they come togheter. Steam sell what you can see as an entry point to both, koikatsu and studio. I have about 8 gigabytes of ram and only use koikatsu's character creator mode (plus charastudio).

Is there any sort of optimization i can make that it won't push the ram to its limit?
