Method:

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.
