Check his installed game size to yours, maybe it's lower?

I have already checked, I have created the checksums file on my installation and verified on his installation, the files are the same and in addition he included 137MB for the soundtrack... so his repack is 1GB or so smaller than my repack.

If you are interested send me a pm for the files... so you can try too. Thanks.

I will check this as soon as I have downloaded the game.

L0v3craft: Try it use LDMF and 1(!) threads only mode from LOLZ!

example:

lolz:dt:dtb1:dtw1:dtm1:dto1:dtd1:d256m:fba4096:mc1023:tt16:mt1:ldmf1:ldc0:ldl5  /or tt8 its barely faster/

and really recommend use defeault SREP level/chunks sizes, aka l512 !

Compressible PCM audio founds or not the archives? Video files? (checking via MSC.)

Quckly testing add delta filters before others, checking compression ratio gains or not. /gain yes = delta+srep+lolz/

I will test those lolz parameters this evening/tonight. Thanks.

Ok I need to add -l512 to my srep parameters, because I use srep 3.93 and -l is zero by default.

msc_tak works , infact it compressed from 55.7GB to 54.9GB.

But I tested srep+4x4/lzma -> 20.3GB and after adding msc_tak before srep and the final size is smaller only of 100MB.

I never tested "delta" before than srep+lolz. I can test it with 4x4/lzma like srep+delta+4x4/lzma. But again Freearc is showing that Elamigos used only srep+lolz, I don't see "delta" in his method.

[kj911]

Use the delta algorithm at the beginning of the chain. It may improve the ratio, it may not.

Use 3.92 from SREP! (The default value of the "l/c" parameters is 512, if not defined separately.) You can play a little more with the a0/a1/a2 parameters, although it does not multiply much. (v3.93 contains decompression bug.)

Did you run MSC with only WAV=1? With the RAW=1 option, how many audio streams does it find? True, unpacking can be a little more problematic this way, but usually it works. What can be a problem if there is no error during packing, but when unpacking it does, because problematic RAW/PCM audio files can appear that run with errors.

It is interesting to note that the small test results show that with MSC there is only an extra 100MB gain at the end of the compression chain, after the initial 800MB size reduction.

In the case of LOLZ, in the case of compression on 1 thread as described above, be prepared for it to take up to ~2-3 days! It might only bring ~5%, but it might be more, since you've run it on 10 threads so far, it might even be a bigger profit.

ps: Hint, try use DLZ replacement from LZMA, from faster compression times testing than LOLZ. Use 256-512MB dictionary.

My preferred switches: -slp -d512m -lp0 -fb337 -mc8192 -cu3 -cm43

I can't believe it... srep 3.2 is the solution.

srep(3.93)+4x4/lzma -> 20.3GB

srep(3.2)+4x4/lzma -> 19.4GB

but in decompression srep 3.2 doesn't work for me, so I tried srep 3.93 in decompression and works.

Don't use delta, it will only harm your ratio. Not useful since many years (if ever).

SREP 3.2 is always a good shout for especially buggy data too.

[Dunnowho69]

i normally use srep_3.92.exe -m5f -l128 -c64 $$arcdatafile$$.tmp $$arcpackedfile$$.tmp for srep but recently have been getting a lots of error: general (de)compression error in srep. and all those were unity games. it fixes if i remove -l128 and -c64 parameters. what could be the reason here ?

Not exactly. There are data samples which give better compression with delta. They are very rare and usually are found in obscure game engines, but still.
