LZMA vs LOLZ & Scan Compress Method

I have some questions about LZMA & LOLZ

Q1) I want to know which one is better?

Q2) i want to know what is 256m, & what it does?

lzma:a1:mfbt4:256m:fb273:mc1000000000:lc 8

Q3) how do i scan and find the Compression like Oodle game?

I know how to find Oodle games. But i don't know how to find none Oodle games so help me please.

1. Depends on the file
2. 256m is dictionary size (https://stackoverflow.com/questions/...ttings-details)
3. Use Game File Scanner for non-Oodle games

Thanks for Reply :)

If i change 256m to 2048m?
it will give me better ratio.
I have test it.

If i use 2048m,
For decompression
at least require 2GB ram
Right?

can you please tell me, where is that
Game File Scanner and how to use it.

Can you please tell me about 256mb?
That link didn't mentioned it.

200m mean 2100Mb ram?
I have seen it in reflate thread.. explain please bro.
Tou know lot of stuffs si please share..

to use d2048mb you need to use fazip, but in compression need 20gb of ram...

[External compressor:rep,mm,exe,dispack070,4x4,lzma]
header = 0
packcmd = FAZip.exe -i0 compress:{compressor}{:option} <stdin> <stdout>

Thanks bro i really appreciate your help...

Yes i have always use FAZip.exe 64 version,
on UA R6 Diskspan.
Its perfect everything is set.

So i have 32GB DDR4 RAM,
i can go up to more right?
Its calculate like 200mx10.5=2100m right?

If i use more ram for compression can i decompress with under 4GB ram?
Without any error? Or
decompress need same memory?

If i use more ram for compressing i can get better ratio and i can finish the job faster right?

so what do you think the d short for :eek:
lzma is limited to 2 thread alone decompresion speed around 40-50 mb,

Please tell me in simple way.

For make your life easier ,i think you should stick with

Srep:a8:m5f:l512+lolz:d384m:mt2

Its more than enough/overkill for almost all games.
Maybe u can use some precompressor ,like x/ztool/pzlib,etc.

Sorry for my style ,i dont want to be rude.
Regards... :)

I don't understand this... Cause I'm new to this.
and I don't use LOLZ, cause it's taking too long.
Please tell one thing. *FAZIP* 64bit use cpu only 25%
How can i let it use 75%? It will be faster if FAZIP use 75% cpu

and i have try LZMA with 2048MB
for compression it used 21000MB 21GB..
still compressing... after it done I'll try to decompress with 4GB Ram and see what happens.

Using "7z.exe/lzma2" as the final compressor I would recommend this option:

Code:

a -txz -an -mcrc=0 -m1=lzma2:d512m:fb=273:mf=bt4:mc=999999999:lc=4:lp=0 -mmt=2 -mx9

Using "LZMA" as a final compression in a single option with a good compression ratio I recommend this:

Code:

-a1 -d27 -fb273 -mc999999999 -lc8 -lp4 -mfbt4 -mt8

Well with "LOLZ", so far today I have not found a good compromise of a good speed and a satisfactory compression threshold in relation to a higher speed.
With lolz continues to do your tests are of interest to everyone.;)

I always Use FAZIP 64 for LZMA so i need to know about it. I don't need 7z cause i will never use it.

So please FAZip64 LZMA info please..
