[Virtools] Performance drop when textures come into view for the first time

[Patrick Hogenboom <p.hogenboom@mcw.nl>]

Hi all, 
first of all, let me wish you a fun and productive 2002 :D !
May it bring what you wish / dream for.

I'm having performance trouble when textures come into view for the first time after I reset / load a world.
What I mean is this :
_I load a cmo file
_rotate the camera
_the performance drops when ever I encounter new objects/textures
  the bigger the texture, the bigger the performance drop.
_after I have completed the full 360 degrees, there is no more performance drops
  Unfortunately, when I reset the scene, the problem comes back !

I think that the performance drop is some kind of AGP swapping / texture uploading to video ram.
But that it comes back when I reset the scene, just doesn't make sense.....

On fast machines the performance just dips, but on low-spec machines, the whole application freezes quite some time...
I've seen this under Dev, the standalone player and the webplayer.

My questions are these :
_Does anybody have more knowledge or an explanation of this phenomenon ?
_Why does it recur when I reset the world ?
_Can I pre-upload all textures to video ram ?
  That way the caching time gets added to the loading time and it doesn't interfere with the user's experience.
_Can I prevent the clearing of the cache, so that resetting doesn't recur the problem ?

Thanks in advance, Patrick
