Whats the proper way to draw objects with vertex arrays?
Is it better to do this before every single object drawn:

    glEnableClientState(GL_VERTEX_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);
// draw my single object here
// gldrawarrays

   glDisableClientState(GL_VERTEX_ARRAY);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);

Or just do once this at the beginning of drawing every object (all objects)?

    

glEnableClientState(GL_VERTEX_ARRAY);
    glEnableClientState(GL_TEXTURE_COORD_ARRAY);
for i:=0 to num_objects do begin
// draw all my objects
// gldrawarrays
end;

   glDisableClientState(GL_VERTEX_ARRAY);
    glDisableClientState(GL_TEXTURE_COORD_ARRAY);

Whats the better (in performance) to do this?

Im currently using vertex arrays and not drawing that much of objects but still i get 25% CPU usage.
I dont know what causes this CPU usage.

I will try to pinpoint this of course in the meantime, but maybe the vertex array "order" is important.
Thats why i asked


EDIT: one thing i noticed, sometimes CPU usage is 25% sometimes 0.
In the same place of map.

I dont have any antivirus or something. But i do have enabled debug info and stuff.
I decreased visible range by 1, will see if that reduced the CPU usage.
