You can use paq8 to do that, if it's really worth waiting

Paq8 low compression speed is the speed of extraction?

Hey @everyone how can pzlib be used instead of lolzx for lzo compressed files ?
aren't pzlib for deflate and zlib detected streams ?
and lolzx for lzo detected streams ?

lolzx is a misleading name.

what is it for then ?

It's not misleading. lolz have nothing with lzo.

lolz, lolzi, lolzx, lol... are simply my namings for each generation and for saving backwards compatibility

Can you point me to a precompressor/compressor that can detect the streams in the .uassets files of unreal engine 3/4 to get a better ratio other than your private tool?

There are no such public tools.

@Fitgirl who uses that kind of tool are they blackbox or you ?

Other groups (excluding Revenants) can only decompress UE3 files, making them not bit-perfect. But in many games it leads to game bugs, including inability to play them through.

Yes lolz is stupid turtle but gives better compression ratio on many file formats in terms of lzma/lzma2 here are my 101tests on it i didn't write too much still but i hope this will be helpful for beginners;)

Real Example for Beginners

Code:

By Compressing Unreal Engine Files for e.g .tfc, .upk, .umap etc etc

I have found that by using uelr+srep64+lolz given me the compression rate was slightly strong than using uelr+srep+lolz

Note: srep options were -m3f -ia- -l512 compressed 1289kb-->848kb

srep64 options were -m3f -ia- -l512 compressed 1289kb-->846kb

   So my opinion is to use uelr+srep64( -m3f -ia- -l512 )+lolz on these unreal engine files



On Compressing sound .pck files compression rate was slightly great using srep64+lolz than using srep+lolz

Note: srep options were -m3f -ia- -l512 56.5mb-->48.6mb(1kb increased as compared to srep64)

          srep64 options were -m3f -ia- -l512 56.5mb-->48.6mb

          srep64 options were -m5f -ia- -l512 56.5mb-->48.5mb

          srep64 options( without -ia- ) were -m5f -l512 56.5mb--> 48.6(9kb decreased as compared to srep64(48.6mb)

 So my opinion is to use srep64( -m5f -ia- -l512 )+lolz on these .pck sound files



On compressing sound .pck files compression was awesomely fast by using srep64+lzma:ultra(but 2mb increase in file that i used to compress) than using srep64+lolz(slow compression), i think lzma is doing better in .pck files



On compressing .forge files with afr+srep64+lolz taken much time(headache) than using afr+srep64+lzma:ultra(fast compression but about 187mb in increase in file that i used to compress

NOTE: My file size was 1.91GB



As far as i know now i have tested a 35,264kb .forge file and the compression test was this:

by using afr+srep(options)+lolz      Based on srep(options) there was slight changing in compression 

by using afr+srep64(options)+lolz      Based on srep64(options) there was also slight changing in compression

{options of srep} using srep(-m3f -ia- -l512) compression was from 35,264kb-->10,397kb

                               using srep(-m5f -ia- -l512) compression was from 35,264kb-->10,463kb

                  but if we use srep(-m3f -l512) compression will be from 35, 264kb-->10,398kb (1kb increased without using -ia-)

                  but if we use srep(-m5f -l512) compression will be from 35, 264kb-->10,464kb (1kb increased without using -ia-)

{options of srep64} using srep64(-m3f -ia- -l512) compression was from 35,264kb-->10,400kb

                                   using srep64(-m5f -ia- -l512) compression was from 35,264kb-->10,458kb

                  but if we use srep64(-m3f -l512) compression will be from 35, 264kb-->10,401kb (1kb increased without using -ia-)

                  but if we use srep64(-m5f -l512) compression will be from 35, 264kb-->10,459kb (1kb increased without using -ia-)

At last i think for .forge files it's good to use srep(-m3f -ia- l512) but it may differ from time to time

Well actually you don't have to 'have' the compressor to know. I learned fron soneone I can trust. lolz has a better compression ratio, I appreciate that. But I don't like to wait hours and days to compress a gane

so what's your opinion which compressor shuld i use instead of lolz(turtle)?;)

Ya better use paq8 XD, 8h to decompress a 100m file :p
lolz is just too slow for me, 167k/s(Yeah I have a noob pc), not worth that speed, so I prefer dlz which also allows better dds compression like lolz.

Try -mc8 -tt1 -dto0 -dm00 and you will see the difference. Use only on textures, e.g. .tfc, .dds, .tex,... while lzma on rest. I just repacked almost 60g xcom 2 wotch like that, game compressed in ~2h how about that. Size = same as FG, not counting extra 6g gain from recoding vids.
