Loading up time

[Bazza]

I know this is a old regular, but here we go again....

A month or so back I upgraded my Terrain Mesh to 20 metre. I am still on FS9.

Following the usual good advice I placed it at the end of my NZ sceneries in Scenery Library along with my Red Baron Topo.

I then found very slow load-up time for my NZ stuff. The "Create a Flight Box" qauge showing the "load up" would run through until it got into the Terrain area where it would stop somewhere between 45 - 55% and just sit. After possibly as long as a minute, it would then move forward a few percent at a time before finally running out of the Terrain load and speed up. This was taking several minutes overall.

Initially I put this down to the increased size of the 20 metre mesh program but thinking about it I wasn't happy with this.

Today I bunged it up to number one on the Scenery Library list. Immediately it loaded at normal speed again, virtually straight through.

Without doing a big test, I am sure the Mesh is working. At Tauranga it gives me the Mount, which is a quick reference for me.

Everything I have read over the years suggest that it should be installed at the tailend of the Scenery list, not the beginning. Any thoughts...?

That's a really good point, I'd never tried that

I might try that tomorrow, thanks for the heads-up

I assume its happening because of the way FS9 handles prioritisation, it probably slows down the loading of scenery at low priority, so that the high priority (top of the list) stuff loads fast. So when its out of order, and the really detailed scenery loads slowly, it slows everything down to a grinding halt, metaphorically speaking

Actually, looking at the VOZ 1.7 User Guide now, I see that they recommend Mesh, then Scenery, then Landclass. This agrees with what you suggested.

Well Done for being observant and picking up on it

A lot of people probably don't realise how much of an impact this can have on performance

Let us know how you get on Matthew......interested to hear the result, surely it can't be just me ? Glad you replied, was beginning to think everyone thougbt I was nuts...over 50 views, no comments ?

I have now had 5 days using it as stated and can't see any problems, everything is loading faster, no other problems showing themselves.

Keep on fiddling, eh ?

[Matthew]

lol yeap.

I'm busy at the moment, but will test it out this evening

Hmmm ... I tried that - on my FSX install (with most of Robin's RealNZ scenery) and got very weird results - around AKL at least - with no real speed up on loading.

I thought that mesh scenery needed to be below any localised scenery?

[toprob]

Library priority really doesn't have any effect on mesh -- the sim will always display the best mesh for the area, no matter the priority. Normally, though, it is accepted practise to put large-scale scenery like mesh, topo, landclass etc, first, then localised scenery on top.
Landclass required a bit more thought, as it can cover up photo scenery if it is higher in the scenery library.

I should have added that I also shifted my NZ Topo up to 2nd on the list....

I have no doubts that this may not work for everyone, however the results were dramatic for me and must have reduced my loading-up time by about 9/10ths. Just in case anyone else is experiencing this type of slow start-up, it may be worth a go....it's only a five minute try-on.
