With UE5 games you normally don't get a good ratio anyways. It is 80%+

However do you checked the game files and they are compressed with kraken level 7?

What game is this anyway?

^^ It was a game named motorslice though I figured out to fix it, I just manually replaced the oodle version ddl on xtool plus addons folder with the 2.9.10 version..Now atleast I get an average ratio!

this game also has mermaid streams. also you dont need unreal engine plugin for it. just do kraken+mermaid
mermaid streams -

Once again hello,
On one of my older posts I asked on how to make my own callbefore and after batch files which mausschieber told me to take a look at the original files..Even after taking a look at it, I still can't figure out on how to actually make it for specific games..Like The game I was planning to use callbefore and after batch files is Dead Cells which Kaktor told me to use xtool erase function to remove the files and mesa to get the .ogg files too, I tried to do it myself but no work sadly..If anyone could teach me abt making it, I would appreciate alot!
Thanks in advance!!

Take a look on this.
I suggest reading it with something like notepad++ to get a more visual reading experience (default notepad is fine too but for such cases I read it always with notepad++).

Anything what comes after
is your playground. There you can do much things.

Also take a look at all the user variables like !GameName!, !DataFile!, etc.
I added some notes as REM inside the bat files. What actions to do etc.

Settings.ini could look like this
It would be good to have at least rudimentary windows batch/cmd knowledge.

^^ Tysm Kaktor!! It really helps alot
