Some questions about games compressions

[max90]

Hello guys
I am trying to compress some games but there are no different in size after compressing i used first freearc without compression after that i used precomp and finaly freearc with ultra compression but like i said it doesnt work
so i have some questions :
1-can someone give me all the compression methods who works on games ? because i just know these one and its not working too "-precomp+step+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8"
2-is there a way to know the perfect compression method to a particular game ?
3-and what the use of arc.ini ?
sorry for the long post and thanks

In some games, precomp+srep+lzma is the best, sometimes pzlib/reflate+srep+lzma is best and in old games without zlib streams, -mx is the best compression. You should check the game with zlib checker, and if there are zlib streams, consider compressing with precomp or pzlib. And if there are no/very few zlib streams, you can compress with mx. Sometimes mx can be replaced by srep+lzma
