pLZ4 (LZ4 Precompressor) - Test
 

Some program I was working on before exam time, this took a day to make, what I noticed is sometimes it gives good ratio and sometimes it doesn't, will properly work on it once I'm free.

Tested on a few Frostbite 3 games such as Battlefield 4, Need For Speed Rivals, also works on Infinity Ward games such as COD MW Remastered or Infinite Warfare, however sometimes you get negative ratio when pLZ4 because of different LZ4 settings and public release version and because of xdelta but like I said, it still needs some work.

UltraFast

working great for me bro

what level to use for Infinite Warfare? I receive negative ratio :(

thx razor, wait reflate ^^

Gosh... Guys, pLZ4 is a precompressor, you are suppose to apply srep and lzma afterwards, oh wow... I released pzlib, I'm guess you used that without srep and lzma.....

plz4 + srep + lzma = negative ratio !

well besides that, there are a couple of people who ran plz4 as it is.

Tested in Battlefield 3 ES and US
Original size 12GB

plz4+srep+lzma = 10GB = Decompression in 25 minutes
pzlib+srep+lzma = 8.80GB (pzlib_1210) = Decompression in 25 minutes
pzlib+srep+lzma = 9.15GB (pZLib_v2) = Decompression in 15 minutes


Both take the same time of decompression, But pzlib compresses a couple of gigas more

Well, BF3 didn't use LZ4 compression at all, afair :)

sorry i don´t understand, plz4 detect lz4 streams or what?.
in that case we need an lz4 streams detector(i guess... for detect what games we can use plz4 for save time.)

Tested in Call of Duty Ghosts does not compress anything

guys the tool is not ready, it decompresses lz4 streams meaning when you apply lzma, you get better ratio, right now, the tool doesn't do what it is suppose to.
Any game from ea using frostbite 3 engine is lz4 compressed, this is why precomp, pzlib, reflate are not going to work, bf3 is frostbite 2, frostbite 2 engine used zlib, which is why pzlib works, bf4 is frostbite 3, pzlib doesn't work, plz4 should.
Grim dawn, street fighter v, codiw, codmwr are just some games that are lz4 compressed, game developers are ditching zlib to reduce loading times because lz4 decompresses much faster than zlib.

Call of Duty Ghosts or the latest Infinite Warfare, does not contain any stream, pzlib has no effect, the best compression ratio with Infinite Warfare and 90% by performing tests on files *.pak & *.sabl, are not able to go down as well, with a good speed and compression rate only with "ulz".

Ok thanks!. So frosbite engine 3 got it. What if those lz package are encripted?.
