Why does it take so long??

[Master Zen]

I was just wondering why turns took so long after your units and improvements had been built.

Turns in HUGE games take quite long. I have noticed that the first part of the turn is the enemy moving. Considering that in the latter stages of the game the AI civs have huge armies, it is understandable why it takes so long.

The second part of the turn is when you finish building your units and improvements. Depending on how much is finished, it can or cannot take long.

The final part of the turn is quite unexplained to me. I have noticed that in this lapse is when Global Warming occurs, when your Galleys sink, when your resources run out, and when the AI civs build Spaceship parts. Yet for some reason this lapse is eternal even when I'm using a P4 1.7 GHz.

I have a hunch: I have noticed that the game pre-calculates combat outcomes since even when one restarts the game, the outcome of a military encounter remains the same each time. Same with exhausted resources. Perhaps the computer uses this lapse to calculate all possible combat outcomes of the next turn which IMO is really stupid because it takes too much time. Yes, it was "cheating" to keep loading saved games until favorable outcomes were achieved but TRUE and HONEST players will grin and bear it even when that Phalanx sank your Battleship!

Also, why does it take so long to build/capture a city in the latter part of the game too?

I would appreciate anyone explaining the reason for these unexplained mysteries to me. Thanx.

When playing on huge maps, turn off all animations except battle (my be even this!), that speeds the game a lot.

The play order in single player is:
- Human production
- AI production
- Human moves
- AI moves
So that "final part" you mention is the time the AI produces. There's quite a lot to calculate, it may take time.

Combat resultats are not precalculated, they are random. But the random seed is by default saved, so you can't cheat by reloading, because the seed is reloaded as well. If you want to cheat, you have to uncheck "Preserve random seed" when you set up the game.

Building and capturing cities late on takes long, because all trade routes are recalculated. That can be quite a lot at a huge map.

Try holding shift

[Master Zen]

So that explains it all... thanx, for a moment there I was considering a P4 3.0, fortunately that won't be necessary (i didn't have the money either hehe)

In any case, if you want better performance, go for more MEM..

A few other aspects can make it take a long time, such a a loss of a harbor. Trades routes will have to be checked. Lost of a captiol and some others that I forget.

[Harovan]

All what is related with trade takes time, in case of a huge map even a lot:

- Building a harbor or airport.
- Destroying a harbor or airport.
- Building, capturing or razing a city.
- The declaration of war (land, coastal and sea routes may be interrupted)
- A peace treaty (vice versa)
- Researching, buying or selling Astronomy, Navigation or Magnetism
- Connecting a luxury or strategic resource with a road.
- Cut off a luxury or strategic resource by pillaging or bombardement.

May be some more, but I tried to be accurate. All effects delay the game the longer, the larger the map is and the farther you are in the game.

Like mentioned above, holding shift down while the AI moves speeds it all up alot. Like if the AI has a bunch of units visible and moves the all the shift key will quickly speed through it all.

I am running CIV 3 on my Athlon XP 1800 with 768mb of pc-133 and it usually don't take very long even on huge maps with all civs. So I think memory may certainly help things out

Also no! You don't need a p4 3.0 to run civ3 fast...LOL. Save your money on that. Just throw in an extra 256mb memory stick and you will be good to go.

[Master Zen]

Heheh, the P4 3.0 thing was just a joke, I'd buy such a monster to play Doom 3, not Civ3..

I think processor power is more important for turn length than memory since many calculations are being done. I have a P3 500 with 256 MB and turns are eternal in the latter stages. When playing on my aunt's P4 1.7 with only 128 MB the game runs noticeably faster even though switching between apps is slower.

[alva]

the difference between:

p3 500 --- p4 1.7

128 --- 256 MB

isn't really a fair comparisson, is it???

[Master Zen]

the only good thing about taking so long is that I can do school work in the meantime...

BTW Alva, hadn't noticed the Tears for Fears quote...nice choice.

I wouldn't be so sure. I doubled my RAM from 256mb to 512mb on my AMD 1.1ghz and the time between turns went down incredibly. I used to avoid any map over 130x130 because the game would crawl by the Middle Ages; now I'm playing 170x170 and the time between turns seems to top out at one minute late in the game.

i'm playing a huge map (160x160 i'm guessing) with a Pentium... oh my god is that a celeron? 500 mhz, 96 RAM... i'm in mid-industrial age... loading/exiting the game and turns take over 3 minutes each now... 16 civs, all alive, i'm the biggest by a good margin and have 500 or so units. i dont see enemy movement at all and it doesn't make much of a difference if i do or dont

[Master Zen]

well, in spite of my experience, I guess the evidence is that memory does affect turns significantly. Guess I'll have to get some 256 MB extra, couldn't hurt anyway.

Now that you've all explained why turns take so long, why does it also take so long to load a game?

[alva]

Huge games can take up to 700MB of virtual MEM!!!
Take a look at task manager, you see.

There is an incredible amount of calculations that need to be done. btw map size is the problem as such, having a lot of civs at once are...
