Very slow 3D startup

Hi Scott,

Haven't used this feature much recently so I don't know when it started happening, but the current beta is extremely slow displaying the 3D view, even when it is showing a small area with regular 3D settings. It used to pop up instantly (though don't remember what TF version that was). It has been slow for some number of versions now. Any ideas?

Nvidia 9600 GT
275.33 drivers (June 2011)
XP 32 bit SP3
AMD 5050e, about 50% cpu load while waiting

TF 4.21 beta
~92,000 vertices
2.0 texture detail
bilinear
download/cache

Thanks,

Steve

Scott,

I have to second this one.  I haven't spoken up about it because of all the tampering I've been doing to TF and it's environment, thinking it might be something I've done.  I'd be interested to know if there are some users who have seen NO change.

Thanks guys.  So once the 3D image comes up it moves/rotates quickly, it's just slow to come up at first, right?  And while it is waiting it's just showing the hourglass and the original 2d map mode, right?

It does seem a bit slow to me when using higher "texture detail" settings -- especially at 4.0.  Then it's fast once it loads up.  I'll have a look at it, though not much has changed in the 3D code recently.

Offsides:
Scott,

That's it, exactly; slow to "load", normal to rotate, tilt, and pan.

Mine is somewhat different.

It will take 6-10 seconds to load up and the program is unresponsive. The progress bar doesn't show much and is only on the screen a bit if it does.

After it's loaded it delays again with hourglass for 2-3 seconds.

If you move off the end of the map it's the same as starting 3D up.

Even tried low monitor resolutions like 1280x1024 and although delays were shorter, still on the order of 4-8 seconds.

But you have identified the culprit. If I turn the texture detail to 1 problem solved. Instantly displays at all the settings I can through it at. I tried to see what difference this setting makes and I'm have a hard time seeing it. Maybe it's because I usually have the Tileset Preference at around 25% of full scale bar.
