That was really mean Benoit :) to promise all that without providing us a scons buildable code :p (ok, I know you use MSVC only)<br><br>Anyways,
I'm really willing to test that, so if anyone (jesterKing?) could take
a look at the linking problems (msvc+scons), it will be very
appreciated:<br>

BGE Scenegraph and View frustrum culling improvement.<br>
<br>
This commit contains a number of performance improvements for the<br>
BGE in the Scenegraph (parent relation between objects in the<br>
scene) and view frustrum culling.<br>
<br>
The scenegraph improvement consists in avoiding position update<br>
if the object has not moved since last update and the removal<br>
of redundant updates and synchronization with the physics engine.<br>
<br>
The view frustrum culling improvement consists in using the DBVT<br>
broadphase facility of Bullet to build a tree of graphical objects<br>
in the scene. The elements of the tree are Aabb boxes (Aligned<br>
Axis Bounding Boxes) enclosing the objects. This provides good<br>
precision in closed and opened scenes. This new culling system<br>
is enabled by default but just in case, it can be disabled with<br>
a button in the World settings. There is no do_version in this<br>
commit but it will be added before the 2.49 release. For now you<br>
must manually enable the DBVT culling option in World settings<br>
when you open an old file.<br>
<br>
The above improvements speed up scenegraph and culling up to 5x.<br>
However, this performance improvement is only visible when<br>
you have hundreds or thousands of objects.<br>
<br>
The main interest of the DBVT tree is to allow easy occlusion<br>
culling and automatic LOD system. This will be the object of further<br>
improvements.<br>
