So, I completely found all answers.
In my game of 260 Mb:
100 Mb consumes GC,
100 Mb consumes scene in glNewList.
And 30 Mb textures in glTexImage2D.
Very well, now I know what to do and how to get it smaller.
Big thanks to all.

Yes after initialize malloc'ed 1.2Mb in C it consumes 1.6 Mb. 4.8
Mb => 4.9 Mb
2. Have you examined smaller numbers for total? Does it scale
