SGI: Computer Graphics

Can anyone confirm that the 2.44 version runs 11% faster on a SGI then the 2.45 version.
And does anyone have a clue why this is?

Different versions of GCC (notably later 3.x to 4.0) can cause slowdowns. And of course comparing somebody compiled in MIPSPro to GCC will normaly show a fairly large difference

11% faster what?
if it's render time, then suspect the compiler.
if it's graphics performance then SOL.

I'm very sure that both versions where compiled using MIPSPRO.
And yes 11% faster when rendering .

three things come to mind:
1) is it only a mips architecture slow down, or it is intel as well?
2) the render pipeline has lots of steps, perhaps a default has changed? nuke your .blender directory stuff and try again.
3) there may be an 'enhancement' to the renderer to improve the quality of the image at the expense of more CPU time.

Ton used to spend a lot of time optimizing the renderer, not sure if they're doing that as well as they used to.
