grand-theft-auto-san-andreas

I'm wondering what is the stream.ini file for in Grand Theft Auto: San Andreas
Also there are the following parameters in the file.

memory      13500
devkit_memory   13500
vehicles    12
pe_lightchangerate  0.0005
pe_lightingbasecap  0.35
pe_lightingbasemult 0.5
pe_leftx    16
pe_topy     16
pe_rightx   16
pe_bottomy  16
dontbuildpaths

What are these for?

If you open stream.ini, you'll see a tag indicating how much memory is allocated to streaming content

I doubt you can achieve anything else than performance improvements by modifying the file. If you want to raise or remove some limits entirely, use Open Limit Adjuster mod. Variables:

 Building is anything placed by a IPL that is not a object (see Dummys or Objects to see what is a object)
