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

[78372]

Prince of Persia : The Sands of Time
data1.arc = All files except bink videos = 726MB
data2.arc = Bink video files (*.int) = 528MB

Method:
data2.arc = bpk = 413MB
data1.arc = 1. srep:m3f+4x4:t2:lzma:16mb:lc8 = 383MB
2. srep:m3f+rz:128mb = 364MB
3. srep:m3f+lolz:mtt0:mt2:mc1023:mtb64m:d128m = 384MB

*Can anyone suggest a better settings for lolz? I am really disappointed with this*

Lolz not always has better output then lzma, but the advantage of it is still decompression speed. Anyways, it depends much on cores and ram you have. Mtt0 sometimes performs better then Mtt1 but it depends on the game, also mtt0 needs at least same cores for decompression. I would try out to set mtt1 instead of mtt0, you dont really need to change mtb on mtt1 as the block size can be the same as the dictionary size, in your case d128. On mtt0 the mtb size should be always half or less then the dictionary size. Another things that can maybe help is setting up fba4096 and gm20. As its a small game you can test those things. For example, if you have 2 threads lolz:mtt1:mt2:d128m:mc1023:fba4096:gm20 (this will use something around 2.7gb of ram). If you have 4 cores and set it up to mt4 it will around 5.5gb. Another go is to do it on a single threat like mt1 and rise the dictionary size to d512 or less (depending how much ram you have). As said, as its a small game you can try out some settings but there is nothing "global" for all games, settings can be good or bad on other games.

just use test22c4b without srep
with lolz:mtt0:d384:mtb196:fba4096:dtb1:mc1023:gm20:pc4 :x2:ldl5 is the best setting for small games.
*note that ldmf work with mt1 only so no mt2 :eek:

Tested with that settings, result is 360MB and it took several hours
Difference is just 4MB with razor and that was a lot faster.
Seems lolz isn't good for this particular game.

What makes me angry about lolz is that there is no logic of use in its options, too many built-in options, and testing it thoroughly I realize that using different options in most cases there is no difference in Compression Time and Compression Ratio.
It is the only compressor that unnerve me by using it, but I've already abandoned it for some time.

Confusing compressor indeed. Currently only 4x4:t2:lzma:16mb:lc8 is the thing that works best for my shitty pc. It's fast and compression ratio is almost same as other lzma settings(2-4mb difference). Though only 16mb dictionary is used here, it actually beats 64/128/512mb dict in a lot of cases.

Good idea. I wonder why didn't I think of that?
