Hi, im trying a lot of types of compression, but still cant find the best...
I take some files - together 681mb

arc a -ep1 -r -w.\ .\%arc%
594mb

arc a -lc8 -ep1 -ed -r -w.\ -mprecomp+srep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8
479mb

arc a -ep1 -r -w.\ .\%arc% -mprecomp:zl98:d1:t-jnf+srep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8
476mb

arc a -ep1 -r -w.\ .\%arc% -msrep+lzma:a1:mfbt4:d256m:fb128:mc1000:lc8
476mb

arc a -ep1 -r -w.\ .\%arc% -msrep:l256+lzma:a1:mfbt4:d200m:fb128:mc1000:lc8
474mb

arc a -ep1 -r -ed -lc512 -ld1600m -mt2 -w./ -msrep+delta+lzma:a1:mfbt4:d158m:fb273:mc1000:lc8
479mb

All of them bad its files from game Lords Of The Fallen - when i use this compressions, everytime i get around 10GB... Guy from another forum make 6.47GB and he said his compression:

arc a -ep1 -ed -r -w.\ .\%arc% -mprecomp:t-nfj:zl11,18,34,39,44,55,68,75,82,83,84,85,97,98:d1 0+srep+exe+delta+lzma:a1:mfbt4:d256m:fb128:mc1000: lc8

But when i try use this, i get same size around 10GB? Whats im doing wrong? Ther is screen of his file from freearc:
