Original file Textures.tfc = 1.0Gb
Textures.tfc + lzma = 712mb
Later used UELR to decompress the *tfc file
after processing with UELR new file size= 1.37G
Test:
UELR(1.37G)+lolz =503mb (took 50min to compress)
UELR + srep + rz = 528mb
UELR + precomp + srep + lzma = 566mb
UELR + lzma = 573mb
UELR + srep + lzma = 575mb (

2mb more)
lolz is the best compressor, but took very long to compress.
