Videos with more lower quality to 720p 4-8Mb/s 30fps (from 1080p 16-10Mb/s 60fps). This should fix current problem for "Daymare 1998" cutscenes lags and late to audio. For lower end PC's.
DAYMARE 1998 cutscenes (720p 30fps)
Daymare 1998 main cutscenes are 1080p .mp4 avc video files with 16-10Mb/s bitrate and 60fps.
In this fix, videos rescaled to 720p .mp4 avc 30fps and even more lowered quality to 4-8Mb/s
Not sure why game can't handle those 1080p videos, but 720p work perfect for me.
Go to games directory:
I recommend backup whole "Movies" folder, or just those 33 files.
For that if 720p videos not helped fix or developers gonna fix playback issue later.
Just copy "Movies" folder from archive to game "Movies" folder and overwrite.
