HERE GO A LOT OF REPLIES. IF I FORGOT SOMEONES, PLEASE ASK AGAIN.
ALL
One general thing I forgot to mention. If you ever turned AGP off (smartgart for example with ATi), you should turn it on for this patch to bring most of its benefits.

I don't understand what d3dquery and dynamicanimpaging is at all, sorry
Well, I don't have exact answer too... just these things might affect how my patch works,
so I tried to repeat my config in order to make fixes/suggestions easier when someone faces problems.
As for savegame... I can't attach it because it's size is above 500Kb, even zipped. Please mail me at 'headden@karelia.ru', so I will mail you back.

That's strange... Please try this 'id_mem_usage=32, insane_mode=0'. This should be stable with every system. Was it crashing when you zoom out before the patch? If not, please mail me 'headden@karelia.ru' with your savegame.

Yes, default settings should do. I am not sure my fix will solve movie stuttering problem. It's a bonus I didn't expect, and some people over here still had intro movie problems both before and after the patch...
There are two ways to uninstall it:
1) Uninstall in terms of functionality. Just set 'patch_on = 0' in Harkonnen.ini
2) Uninstall so that game can't detect anything later when it gets patched from Firaxis: download and replace original 'zlib1.dll' (see bottom of the post #1).

Well, this might be GPU overheating (for eaxmple dusty cooler) or it can be problem with power supply as well. Modern video cards state 300W as minimum. I could live with 250W for some time, but I have P3, and even putting 2nd HDD sometimes caused HDDs to restart on-the-fly, it was very scary sound with all that info... so if your power supply is below 300W, I suggest upgrading it to 300, or better 350-400W.

Same problem, same recommendation
Amazigh,

This game has more geometry than it deserves. And from my experience, at least ATi cards eat much more power within geometry-processing unit rather than with rasterizer. So, any overheating or power problems will surely strike you via civ4 if you have a chance to have them.

2Gb systems sometimesw catch CTD, this patch solved some of those problems for 2Gb systems. I mean that with 2Gb systems speed won't be improved, but stability will.
JackTheNarrator
Yes, probably

Thanks! I still don't know if there is memory leak or not. If there is, my tech just reduces its effects. I really faced invalid memory allocation by XML part and another oldschool ASM programmer faced invalid geometry deallocation, but I didn't investigate origins of these problems.
Amazigh
Just yesterday I had a problem of my HDD going off and on. I was damn freaking scared... all sources were there. Then my ATi after reboot told that its power plug is not in place. I opened PC box, plugged it in better, and the problem seems to have been solved.

Try 'insane_mode=0'. It's fast as long as video memory is fast... with 1Gb it's not so important.
Michelangelo
I think yes. Some intel graphics card got improved above in this thread. Though I don't remember if it was TnL card or not. Just give it a try. A patch is easy to be turned off, just replace downloaded 'zlib1.dll' with original 'zlib1.dll' (see post #1) for the link. I'd recommend 'vid_mem_usage = 32', 'insane_mode = 1' for starters. In case of bugs, set 'insane_mode = 0', it should work fine.

1. You should check VM_Size in task manager instead to get improvement measurements.
2. My patch works with geometry data and it was always able to free at least 100Mb with 'insane_mode = 0'. Does blue marble affect geometry data or just textures?
3. As I saw above 'Ti4200' cards impose performance penalties with my patch which are comparable to performance increase with reduced memory usage, so overally it usually works around same level.
Fallblau
Hmm... another small decrease with Blue Marble (was expecting ~200Mb). I'm going to their thread to ask some questions about geometry. Try reducing 'vid_mem_usage' down to 40, probably it'll help some.
Bast
Probably yes, it depends on the origin of these slowdowns. If they come from memory usage, fix will fix that. Sorry for tautology
JorenCombs
I think Windows is just reserving space in swap file for later swapping out of physical memory pages. Changing file size is quick operation, so it increases swap file size, but doesn't actually write something to it. Just a guess... Also VM_size is entire game allocations size. Mem_usage is how much of this is devoted to physical memory plus how much of physical memory is devoted to cache files.
Smidlee
Yes, 2gb people either received no gain from this patch or the gain was increased stability. If you had no CTD yet, then probably you don't need it.
