Game Size - 70 gb

Install time - 35 min.

sorry if these are a silly couple of questions but with xtool what codecs did you use? The "Game File Scanner" tool shows zlib and lzo strems but I'm not sure if there are others. Also what's pmt? Never used the razor tools before sorry if thats got an obvious answer.

uelr processes the lzo streams, xtool will process the zlib streams.

PMT = parallel multithreaded tool

RZ is a single threaded compressor, so PMT splits the data input into chunks and compresses those chunks in parallel to essentially harness multithreaded operations and speed up encoding / decoding.

Ah, thanks for clearing that up with UELR, I got distracted to properly figure out what it does and wasn't sure if it handles LZO streams or did something like unpack UE3 archives. Thank you for explaining what PMT does, saved me a lot of time! It's fascinating how people are able to come up with these solutions honestly.

English Only.

Code:

uelr+srep+lolz

*.bik, *.pck (videos / sound paks)

Code:

srep+LZMA2

11.5GB ----> 4.3GB

With all other languages:

13.2GB ----> 5.9GB
