Best Compression Methods for 'Specific' Games. Q&A

[ZakirAhmad]

Compressed Mad Max Fury Road with ztool srep lolz to 3.90 from 32gb.<br>
The srep dictionary size is only 2200mb. I used settings srep:m2f:t1:l512:c512.<br>
srep compressed it to 9.9gb then lolz to 3.90gb. <br>
The only problem with doofoo settings is that he used multithreaded srep because srep with m1 and m2 uses multithreading hence reduction in co.pression ration. He also used l32 and c 32 whre as i used l512 and c 512 because my ram is only 4gb otherwise i might have gained may be better than this. <br>
The whole point is to limit creation of temp file which interupts fast installation.<br>
<br>
How can we achieve fast installation?<br>
The things i recommend is <br>
1. If useing prexompressor with multithreaded support, do not set processor useage to 100% because their r other tools like lolz srep etc in compression chain which also use cpu. If u set precompressor(1st tool in chain) usage to 100%,, it will restrict other compressors like srep and lolz to use cpu in parallel and hence the compressors will run one after another not parallel.<br>
#2. If a game is heavely compressed with srep like in mad max use m2f setting instead of m3f or m5f. It will in most cases restrict decompression dectionary to managable size.<br>
#3 useing multithreading for lolz when using precompressor is of no use in most cases i guess because if precompressor cant process much, it will automatically restrict lolz data processing or lazma etc.<br>
<br>
#4 use latest srep by profrager. And set memory usage in cls as 100%- 1250m. Why 1250m?, i observed if ur win 10 pc is idle, it uses only (1250mb ) of ram (at least in my case), what if we use 100% memory usage or 100% - 256m? <br>
I would not recommand doing this. U known in win 10 their r two ways to free RAM when it senses RAM is full, one is to use page file and another is to use compression and then page file. So when u set ram usage to 100% and if srep needs ur 100% of ram, it will first fill ur 100% ram and then will create virtual temp file file. But in prder to iuse 100% ram windows has to move own components to page file and or compress, this will increse instillation time exponentially and will make using pc hell impossible!<br>
However I have read that srep uses memory from free pool but i havent foumd doing it that. It just uses full ram if I do not use it that way.<br>
Also m5f -ia- swotches of srep promises to ise less ram without the cost of speed, so if any one has got fast computer please compress madmax with m5f -ia- switch and report decompression memory isage by srep back here. Use srep 3.93 because it provides decompression ram usage after processing the file.<br>
One more thing, please do press thanks, if u find this helpfull.<br>
