This is likely a throughput issue and not what this fix was intended for. This was designed to fix specific freezes with certain movies (john Wick 2, Serenity for example) which seems to have been successful.
I would try mounting over NFS if you can, and using fstab instead of Kodi’s mounting options. I use NFS via fstab and watched Arrival on Sunday and it was flawless. Not sure how the bitrate compares to Gods of Egypt but there was no issue in terms of playback for me.
EDIT: Pretty similar bitrates for the video tracks on both which is all I checked against.
