Today’s patch replaces the current movie files with high-quality movie files.
If this causes performance issues, please use the beta branch “movie_beta” to opt out of the high-quality movie files.

To access the beta,

1)Open [Steam]
2)Select [Library]
3)Right click [Conception PLUS: Maidens of the Twelve Stars] and select [Properties]
4)Select [BETAS] tab, then from the pulldown menu, select [movie_beta]
Close the [BETAS] tab and the update should download automatically.
