Yes have obtained a 45 MB log file :-/ only for some seconds of SuperTuxKart
I have found something
SuperTuxKart use (or PLIB do that ?) drawarray BUT for EACH polygon
(me for cow3D I draw 1000 polygons each time that I call drawarray)
So for around 64 frames generated then drawarray() is called 68891 times
==> around 1000 drawarray per frame
(but intro dont have much polygon, last drawn frame call drawarray 4400 times
(( )==> Each polygon is truly draw with a drawarray
( drawarray can draw a full (single material) object)
Bad bad bad :-/
=============================================
From PLIB sources
void ssgVtxTable::draw_geometry ()
{
[...]
glDrawArrays ( gltype, 0, num_vertices ) ;
[...]
}
void ssgVtxTable::draw ()
{
[...]
draw_geometry () ;
[...]
}
But i didnt found what/where call draw() in SuperTuxkart or PLIB
