Since this is the 1.09e memory thread, I figured I'd post that I haven't seen memory-related crashes since this patch. I am still getting the occasional 'in combat' freezeup though (quit & restart game time). Thank goodness for autosave.
I regularly play on large maps with 10 opponents. I've made it past Turn 300 a couple of times now before deciding I've pretty much won and start a new game.
AMD Turion 64x2, 2 gigs memory, ATI Mobility HD2600, decent free hard drive space. Windows Vista Home Premium.
I use the old 'define min & max virtual memory at same values' trick, paging file size set at 16,384. Dunno how much of an effect this is having on memory performance since the patch, but I figure I'd mention it in case it might help anyone.
It looks like they are at least getting a handle on this for most of us. For those still having problems, posting your system specs and error files is always helpful to the developers, so they can try to figure out what configurations are still having trouble. As the OP on this thread did.
