[Papervision3D] Optimizing performance: anything else I can do?

[Alan Pinstein]

Ok, so here's a few things I just tried:

1) I was wondering whether texture size has an effect or not, so I  
cloned one of the panos but shrunk it down to 25%. So the texture went  
from 3 segments of 2400x910 to 3 segments of 600x228. There was no  
difference.

What is somewhat noticeable is the mix of CPU load:

> CPU usage: 57.06% user, 29.75% sys, 13.19% idle

Very high sys load, and some idle time. To me that screams of resource  
contention or iowait. However I have confirming with network  
monitoring and iotop (dtrace) that there is no IO going on.

Maybe this is a clue... I know that flash *can* get to 100% CPU, so I  
wonder where the resource contention is? Anyone have any ideas?

2) Tried this before, but I'll try again.

Yikes! This time when I tried it the images got totally messed up,  
horrible graphical bugs. Maybe that's why I didn't use it.

On that note, I am using v883. Should I be using trunk or something  
else?

Anyway, from all I can tell mipmapping cannot possibly help when using  
textures at original size.

3) From my code:

Sorry, no dice.
