Help me compress files much more efficently

[TadAws]

Hello everyone, this is my first time posting here so I do apologise in advance if I posted this in the wrong thread
But I recently got into repacking games, and I use a lot of tools to do so
However most games I compress, they only go down by a few GB compared to many repackers who has it down by 10s of GBs, how can I also compress games down by a lot?
I have attached an image of what I am using to repack my games and make bin files for setups
Thanks very much
