4GB Patch
« on: July 07, 2011, 02:22:55 pm »

Does it work with Dwarf Fortress?

http://www.ntcore.com/4gb_patch.php

(Maybe it could help against world generation errors...)


oh and hello forum!  :)


Edit: I used it for performance improvements for the EU3 mod MEIOU... well i noticed no changes  :)

I dont think it will help too much. DF is not that heavy on ram, instead, it is super heavy on processor, and it is almost always the first PC component to bottleneck the rest.

Ever generated a world, or tried to embark on a large site?

I think it would help for 64 bit processors (read: all computers made after 2005). It shouldn't glitch out or anything (unless you still use an old 32 bit processor, in which case it would probably fail badly), but the benefit might be less than one would expect.

If you read the page itself, you'll find that it only works when you're running a 64-bit operating system, since otherwise the upper 2GB of address space (or 1GB, if the proper option is enabled) is reserved by the operating system.

This tool might not even work correctly - some code is written to assume that a negative pointer address (i.e. >2GB) is an error condition.

I've found an article about this tool (german only). A comment says after patching the programm can adress 3GB of RAM under 32bit Windows (instead of 2 GB) and 4GB under 64bit Windows (eg. Win 7 64 bit).

http://beatmasters-winlite-blog.de/?p=4371

So i've tryed it on my own  :) . Patching works fine, after loading my old save (phoebus 31.25v17, 3x2 (?) embark, 80 dorfs, 60 clowns) there are still unchanged 47 fps. After a few minutes of playing there were no crashes so far.

It patches how much virtual memory a program uses. This is your page file. So, if you have one hard drive this will probably slow things down, not speed them up as your HD struggles to do multiple things at once.

It patches how much memory space is available to the program, period, whether things are being paged to the disk or not. "Virtual memory" does not mean "memory paged to disk".

thx dr. google i found out, that a user named TwelveBaud used this method for avoiding a crash during large and long world generation about one year ago:

http://bay12.dyndns-ip.com/dwarves/mantisbt/view.php?id=2715 

the status is still on "new".

Here's the original thread from the MEIOU forum where i found the tool (some posts below):

http://forum.paradoxplaza.com/forum/showthread.php?535848-FAQ-MEIOU-TD-Important-info-2Gb-Fix-Tutorial&s=c7f410fb4e0c631556cfa5b68e4be861


Edit: The patch seems to be the solution for this bug as well :

http://bay12.dyndns-ip.com/dwarves/mantisbt/view.php?id=136

Now larger embarks than 9x9 without crashes are possible, i tested an 12x12 embark and it works!!!  :) (but low fps, below 4)

Why?  It's about an "aftermarket" change to the game's executable, basically an automated hex-edit.  How is that not DF Modding?

Yes. Bug is for problems in-game, not for programs made to make it run better.

The bug reports forum hasn't been used in a long time anyway; you can't even start new threads there. Everything's moved to the Mantis bugtracker now.

ok, let us call it a "bugfix-mod"  ;)

Edit: Has someone else tested it already?

No, because it doesn't fix any bugs.
