serious slowdowns on some maps

I think your PC is relevant, and this is probably your problem.

This from the game guide:

The default installation will place a shortcut for the GameOptions programmes on your desktop. We HIGHLY
recommend starting the game via the GameOptions programme at all times.

This game will use a lot of Windows memory, so it is best if you run it on its own, bar any use of your browser to read the
game manual. It wants "real RAM" and so it is best to start any other memory hogs after launching the game, should you
wish to try say some word-processing or spreadsheet programme - start these after the game is launched.


The game wants as much real memory as possible, so for optimum performance, especially on lower end machines, try
to run the game with as few other windows programmes running in the background as possible. Also, since many other
programmes will fragment the main Windows memory, it is often a good idea to reboot the box and start the game as the
first thing run. Do not run it in paralell with any other games! - only windows desktop type applications.

Screen Size is the first determinant of horsepower required. The larger the screen size you choose, the more pixels the
CPU and graphics card have to push about. Especially with a lower end machine, you will have to find the screen size
that suits your hardware's capability. The smaller the screen size you choose, the higher the performance you will get.

Full screen DirectX mode is the fastest graphics mode. There is no Windows desktop to worry about co-operating with.
It will therefore likely be of most use to those users with older machines and/or graphics cards.



Hope this helps,

so to conclude, trees eat memory?

because so far i never noticed any problem...

PATHFINDING will eat memory as the AI decides which way to go. The more difficult terrain on the map, the larger the map, and the more enemy units to pathfind with - the more time it will take, naturally.

A map consisting largely of clear & open terrain - will not require much pathfinding.

So - you have a large AI force, on a large map stuffed with bad terrain - naturally more CPU will be required to process the AI force.

And your computer will make a difference in number crunching - a test game on my new (5 year old) Dell with single core P300 and 1 GB of RAM, takes a minute. On the 12 year old W98 box with a P120 and 256MB, it will take 10-15 or so minutes to process an AI turn of the same sort of size (map and force). My little netbook with a weedy Atom processor but a gigabyte of RAM takes 3 or 4. RAM is likely to be the main need since each unit is making a path list of its own. An AI helicopter unit will not require much CPU (all moves the same cost) - but will require more bytes to store its paths (and will test more potential target movement hexes = more bytes).

Also - AI formations a long way from contact will generate a formation march path to handle larger movements. each HQ may well need a lot of pathing of a large chunk of the map to find a way round a load of mud, trees, a river cross the map etc. So larger maps will generate much more AI pathfinding calculations - the more nasty terrain, the more it will need.
