Unreal Engine 3/4 and lolzx Compressor

[danswano]

What is this compressor "lolzx"?
Is it available for public or it's just for personal use.
Because i'm seeing a very good compression ratio when used with Unreal Engine 3 or 4 games especially the textures.
Can you provide a detailed info about it please?
Thanks.

private compressor

The better ratio is due to the use of a precompressor (Pzlib)

LZMA is better

Are you a lolz developer?

LZMA didn't give me the same ratio.

You can use Lzma Ultra settings, but you need 16 to 32 GB of RAM

[Jiva newstone]

Yes . lzma2(7z) is best and fast

[danswano]

@JIvisPC
give us the parameters for lzma2 to get a better ratio or at least the same as of lolz

Afaik, lolz is slower than lzma when compressing, but very fast when decompressing. It supersedes lzma by decompression speed and ratio.

Do you have the compressor?

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

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

Guys, this is a private compressor by Profager. He may gifted it to fitgirl, or may fitgirl bought it from Profager. But it's not a public compressor afaik.

Ofc not, and if I had I would have never used it.

Then how you knew it's slower? did you just read that somewhere or there some benchmark tests?
There is no single compressor on the internet can compress unreal engine games 3/4 in such ratio better than lolz with such a very good decompression speed.

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

Sometimes it's worth the waiting, some games might end up with LZMA for 4.38 G.B and it's really sucks that you can't fir that game on a DVD5 just for those extra megabytes, and here comes the role of compressors like lolz to make a better ratio when needed.
I hope i can get my hands on it or something similar soon.
