Okay, i lost a day, but i get this.
So, i have a huge project, last month i worked only with mathematica (angles of players, corrections, etc), and i was really dissapointed with the falling of FPS and memory size.
1) I commented 99% of code: includes, startup and so on.
When i run nearly empty script, i got 2 functions running, empty screen and 400+ fps.
2) I uncommented and optimized some INCLUDE files, so the summary size of scripts increased... i got still 2 functions running, empty screen and 280 fps.
And its not the end.
Why this happens? Why FPS depends on number of strings, but not on number of running functions?
