Uninstall all virus scanners, firewalls, toolbars, download accellerators and whatever. They all got lots of DLLs which get loaded into every single process. Each taking a good chunk away from the available 2GB.

Did you try patching the game? Furthermore, which game are you playing: DL, or DA?

try this web page http://support.microsoft.com/kb/833721 it might help, not sure if it helps 64bit OS's

Should allow 32bit apps to use 3GB of virtual memory instead of 2GB.

TotA is more efficient and if you want to play gigantic/immense galaxies then upgrade to it.

Many of us manage to play the game regularly and for hours at a time without encountering any errors. The problem would appear to be unique to your environment. Try using msconfig to clean boot the system and see if the problem goes away.

i am running Windows XP and everything on it is updated. i understand the RAM limitations of the OS, which makes me doubly question why this game fails to run reliably on a system for which it was written. i have the most up to date versions of Gal Civ and Dark Avatar, and i save the game every turn, and have the game set to auto save. The game doesn't crash... it just says it doesn't have enough memory to save the game. This is incredibly annoying. Especially if you have made numerous moves during a turn that can not, then, be saved. i play on the large map, not the huge or gigantic ones.

Does the game run any better under Vista whose RAM requirements are different? i can install it if so.

This is a really fun game to play, but i have never played a game before that simply fails to run on even the most maxed out systems. It seems to me that with the length of time this game has been available that these bugs would be worked out by now.

You didn't think it was worth mentioning previously that you're running via bootcamp on a Mac? And you're blaming the game and the coders when you're trying to run it in a totally unsupported manner on an emulated OS?

Lemme stress on rls669's comment if you don't mind.

Emulated OS'es (include even Linux, in that category would you!) can get a little tricky as they aren't really stock compatible with numerous different programs or even, variable conditions related to the actual machine(s) "setup".

What you have is a workaround Mac which pretends to be fully MS ready using a bootcamp alternative environment... you must cope (somehow) with such situations cuz it IS highly probable these may occur often or by luck, rarely.

I can happily say, though, that GC ISN'T a "piece of crap" (as you seem to imply) since it works perfectly well on my very low-end XPro/SP2 driven P4/1.5 (along with only 512/Ram supported by a tiny/sufficient/fixed length 1.4 pagefile.sys!); No crashes which can't be handled properly or if any, no annoying bugs whatsoever, unbearably slow in some specific gameplay "areas"... but, i don't care - it is, afterall a TBS game with very high graphical demands loaded into the above minimal PC (equipped with a genuine Intel CPU, single core). Turned off a few things (thanks to SD coders for the options, btw - shows me that THEY care about their customers, even if they own almost obsolete computers.) to MAKE it worth playing, and it does.

The problem isn't at all from GC coding or, more importantly, its minimal basic (very well explained both here on site and in the PDF guide given.) requirement(s), it is actually from your particular "pseudo" PC - no offense intended.

Troll much, Uranium - 235? We can probably try to keep things a little more civil here.

(I'm flagging your post for possible removal.)

Oh please. i didn't mention it because i knew some friggen idiot, such as the morons who attempted to flame above clearly show, would jump on the fact that i am running Windows on the Mac as THE problem... which, btw, it CLEARLY IS NOT. i am NOT running Windows under emulation, i am booting straight into it, and i have drivers downloaded and installed from the sites themselves for the WinTel components. Blithering idiots, can't wait to flame a Mac, eh? BTW, regarding the price tag... at least i can friggen' afford it and half of you would own a Mac if you had either brains or the wallet to do so, so lay the **** off. The Mac is not the issue. Bootcamp is not the issue. i am not running this game under Parllels, or any other sort of "emulation."

The game runs out of memory on saves. i can play the game, with no problems. But as the game gets larger, with more ships, and planets colonized, then it runs out of memory. This is not a problem with my MacPro, it is a problem with the Game. i run CIV IV and have absolutely zero problems. Are you going to tell me that GalCiv is more intensive than Civ IV? Please! Furthermore, i am hardly the only person having the memory problem. This site is chock full of such complaints, but of course you would have to know how to read to notice them, eh?

And one more time, for all those who might still be a little confused... i CAN play the game. i can even play the game on a gigantic map if i want. The thing runs quite smoothly. But, after several hours of play and the game becomes interesting, then it runs out of memory. Therefore, i have begun playing on a smaller map, and decreased demands on the system, but it still does this. Therefore i can't ever seem to finish a game. i think my irritation is quite justified.

i ask again, are there any differences in performance on the memory issue under Vista?

If you looked around the forum a bit you'd see a post by one of the devs made within the last few days, to the effect that bootcamp is absolutely not supported. It doesn't matter that the new Macs have Intel processors, they're still not running a native pc bios and pc software is by no means guaranteed to work.

He just said that the game crashes even on smaller maps...
dunno, just make the game autosave every turn and reload if it breaks.
