Hey folks,

I have a moderate computer, and civ 5 runs fairly slowly. I've been looking through my task manager, and discovered that civ 5 runs as 32 bit? Why not 64? My system is 64, and I assume that would help a lil' bit.

Can this be fixed? Does this matter?

Do you know how to run a DXDiag and post it here?
 
Sure do! When I run DxDiag, it launches the 32 bit version by default. Here's the 64 bit one. Culled.

it is a 32 bit application. you can't force it to run as 64 bit - it needs to be compiled to run with the x64 architecture to work
this doesn't really impact performance until you hit the memory limit of the address space (using over 1.8ish gigs of memory)
 
To build on what vexing is saying, the commands to perform basic mathematical operations are different between 32 and 64 bit, which necessitates the recompile. But unless the code is specifically refactored to take advantage of the greater number and size of registers or greater maximum memory available in a 64-bit environment, all you do is force the system to unnecessarily process larger values than is needed. Larger values means more processing, more processing means worse performance. CiV never comes close to hitting the memory limit of a 32-bit application in Windows so it doesn't need the extra memory; refactoring code is a ton of work for what would amount to at most a couple percentage points in performance while potentially introducing dozens of bugs.
 
Not only that but I doubt most of the support libraries linked against CiV are 64bit. There are tasks that can be programmed to take heavy advantage of a 64-bit processor but for the devs its a pretty poor cost / benefit ratio. You'll spend weeks writing new code that will only work on a subset of computers and also introduce loads of potential bugs.

unfortunately that's not true - large and huge maps hit this limit later in the game, and then start thrashing =(
 
You know, I hadn't thought about it...but that explains a lot about this game's performance issues with larger maps. It also explains why those problems have proved so intractable.
 
Thanks for your responses folks. It's regretful that the code isn't compiled to 64 bit productivity, though.

I have learned something today :D

CiV was built with LARGEADRESSAWARE. Basically this means on a 32-bit system it should be able to access approximately 3GB of memory and on a 64-bit system (running under WoW64) it should be able to access the full 4GB. So if people are finding it getting stuck at 2GB or so something is going wrong. I've never actually checked but will make a point to on my next monster huge map game.

Another problem that plagues apps like this is fragmentation of data structures. When you first start, everything is all in a nice neat block of continguous memory so your arrays and tree data and such is all in the same relative area making caching very efficient. As time passes and data gets created and destroyed, this data gets spread all over the place. This translates into lots of cache misses and can represent a major slowdown to the game. Unfortunately this problem can be stubborn and the fix challenging to integrate after release.

Hitting the maximum addressable space doesn't cause a program to thrash, it just crashes straight to desktop with an "Out of memory" error. Sins of a Solar Empire suffered from this for a long, long time until better optimization occurred in a patch a few months back. Thrashing occurs when a program tries to access memory not currently in RAM and the system has to retrieve it from the swap file on the hard drive. The hard drive being 2-3 orders of magnitude slower, every read operation of the application's memory takes much, much longer. Remember, although each application gets 2 GB of memory available to it by a 32-bit OS (3 GB with largeaddressaware), there won't necessarily be enough RAM to store every application's requested allotment. This was a big problem back before RAM got so cheap, particularly during the Win95-98 era, and those applications didn't come close to hitting the 2 GB cap.
