Subject: 64-bit Curious but Yellow

I have to admit, I have a fairly old computer that I have to wind-up before I use it :), and I'm thinking of using my bonus in Nov. to get a new one, though it always makes me nervous to actually spend money.  So I'm wondering about this 64 bit thing.  How much of a difference does it reallly make in render time.  I'm no hardware guy, but logically wouldn't a 64 bit computer be twice as fast as 32 bit that's otherwise the same?  Or is it more complicated than that?

In Poser in general, not terribly useful because Poser is a 32-bit app.  In Poser render time, negligible difference - if anything it'd be a bit slower because the OS has to run 32-bit apps in an emulator, but it works.

The benefit of 64-bit computing isn't speed, it's being able to address very large amounts of memory in applications that are written in 64-bit instructions.  Since Poser isn't, at least up to this version, it doesn't help you.  However in other apps, like Vue, Cinema 4D, 3ds Max and Maya etc. that have 64-bit versions, it can be VERY nice, because you have effectively no limit on memory the program is allowed to grab - this can enable you to render very complex scenes that are much harder to get done in 32-bit applications.

So, if I''m actually doing the rendering in Vue, the 64 bit thing will allow me to  do more complex scenes?  This would nice, since things seem to freeze up bad after about 3 characters.  I did see that the next version of Poser (Poser  Pro) would handle 64.

Re: the upcoming "Poser Pro", the renderer will be 64-bit, which is imo the really important part anyway and what tends to break your work with previous versions of Poser, so that's a nice change.

If you use Vue6, which you seem to, then don't hesitate and get a 64bit system and bang in as much RAM as you can afford, it really is worth it. pjz99 has said it all really!

Check out my image here, this has 28 fully textured M3's and a complex room model all rendered in Vue6Inf on a 64 bit machine with 8 Gig RAM. no specific atmosphere with just a hint of DOF, took about 30 minutes to render in Final.
My olde 32 bit pc wouldn't have even looked at it before running away and hiding!

So, this isn't using the ecosystem thingy.  This is 28 actual Poser figures?  Wow, I really do need to upgrade to 64.  :)

Nope, not eco system, if I'd used that I could have had literally hundreds or even thousands in there, great for long distance big army type scenes but not for what I wanted in this one!

But is it true that a  64 bits Os can allow  2 gb ram each 32 bits softs and you need an 64 bits installation to use more than 2-3 gb of Ram on one computer?
Example:
Hypothese: Two 32-bits softs  and an Os and 4 gb ram installed on motherboard

----On 32 bits system ,like XP ,you can manage 2 and ,with parameters manipulation ,3 gb of ram maximum for loading OS and after the two softs
----On a 64 bits system ,like XP64 or Vista 64 ,you have acces to all the 4 Gb for loading Os and  the 2 soft, each  one can have access to 2 gb max
It is correct ?
If true a 64 bits sys will be better even with 32 bits softs because generally  for the graphics soft the more ram that you can have better it is


thefixer ( ) posted Mon, 08 October 2007 at 1:02 AM

The extra RAM won't be much use if your app is a 32 bit app, true.
Fortunately Vue6Inf is a fully 64 bit compliant app to it can use all the system RAM available to it!

Keep in mind that we are talking about 64 bit Operating Systems here.
Just about every CPU you can buy at moment is actually a 64 bit CPU, so almost every computer you buy will be 64 bit machine. If you can get it install both a 32 bit OS and a 64 bit OS on the machine. That way you have a choice and if you do encounter a program that will not behave in a 64 bit environment you can always fall back.
In a new machine with all new hardware 64 bit Vista should work. If you want to reuse old hardware 64 bit XP is probably a better idea. For the 32 bit OS always go for XP (proven technology).

My emphasis ^
No. Each program has it's own address space, and will reference as much system RAM as needed.
If you are running two programs (and you are actually running dozens on boot up), neither is limited by anything other than: 'free RAM' + page files.
If a program attempts to use more than available:
a) 'insuffiecient memory' message, aborts command.
b) crashes
Graphics software (and any performance based software) generally just crash; because checking system resources for every single command execution is a HUGE performance drain.
I.E.  If one program (Poser, for example) is using 1GB out of 4GB available; then the second (Vue 6i, for example) can use 3GB without a hitch. Close Poser, and Vue can then use the extra GB.
That would be true for 32-bit or 64-bit OS/applications.

The difference is the size of the 64-bit address space (2^64, or ~17 billion GB) vs. 32-bit (2^32, or 4GB). No current OS can use 16 exabytes of program address space, even if you actually had that much RAM installed. There are imposed limitations. I think 16GB for Windows and MAC, 64GB for Linux, I could be wrong about those figures; but there is some imposed limitation at this point.

Important note, the above is true for a 64-bit OS running a 64-bit application.  32-bit apps running on a 64-bit OS are still limited to 2GB, or 3GB if they were compiled using a certain switch to allow it, described here:
http://www.microsoft.com/whdc/system/platform/server/PAE/PAEmem.mspx

I can tell you from direct experience that Windows XP 64-bit can address at least up to 20GB of memory without trouble - even though I only have 8GB on my machine, I have a large page file (8GB more by default) and the page file can be extended dynamically when needed.  I once rendered a very complex hair setup in Cinema 4D 64-bit as polygons, and the process grew to 20GB, but ran smoothly otherwise (took a bit of time though!)

The idea would still hold true for 32-bit app. on 64-bit OS.
Each application has it's own address space, and RAM is not partitioned on a 'per process' basis...
But yeah, if you hit the architecture's max. address space usage limit, then an app. obviously can't use any more than that, no matter how much left over you have.

That switch only works for 'large address aware' programs. Not all 32-bit progs can use it. You would have to consult technical manuals/docs to see if a specific program supports large addresses.
64-bit OS doesn't use that switch, it doesn't need it. If the 32-bit program is 'large adress aware' then the LAA switch is already working under 64-bit OS. It was an extension of OS hosted address space from 32-bit to 36-bit.
I suppose that is a benefit of 64-bit OS right there; but it won't do anything (either the switch or 64-bit OS) if the address space of the application isn't configured to use it.

I also found that the 'imposed limit' of Vista 64-bit address space is 8,096 GB. Guess I was off a little with the 16GB figure...😊
Oh, well, it's still an imposed limitation.

ive heard that Poser Pro is 32bit and the render engine is 64bit, so does this mean that because the main program is 32bit poser will be limited to the amount of ram it will be able to use during rendering or will it be allowed to use 4gb's of ram during rendering and 1.5gb's during normal poser running??????

Getting old and still making "art" without soiling myself, now that's success.


pjz99 ( ) posted Mon, 08 October 2007 at 8:35 AM

There "shouldn't be" any practical memory limit while rendering, which imo is the really important part of the job anyway, I never ran out of memory in any other situations in Poser 6 or 7.
