Yes - Under 64bit Windows, SU can now address up to 4GB RAM. (I have tried it with a huge render.)

Do we have to do anything to XP (e.g. the /3GB tweak) and/or 32-bit Windows 7 and/or 64 bit Windows to use LargeAddressAware?

Do we have to do anything to SketchUp?

You don't do anything, but if you have a 64bit OS, SketchUp can address more than 2GB of memory, up til 4GB. Just make sure you have a 64bit OS and at least 4GB RAM.

Strange you guys didnt get the same message. This happened on 2 completely different machines. 1 a custom built desktop and the other on a Sony Vaio laptop. I will try reinstall later and see if I get the same message and I'll post a screenshot.
Thanks for your replies.

cadmunkey · 17 Jan 2011, 21:09

Just reinstalled but the message didnt appear. Obviously the info is still in the registry so doesnt need to do it again. I'll check out compatibility settings in the Microsoft forums to see what I need to do to take them off.

Al Hart · 17 Jan 2011, 21:22

It used to be in XP that you had to change the OS to give you 3GB rather than 1.8GB of 32-bit space. I presume that fix would still help with SketchUp.

The other half of my question was whether you still had to do something to enable LargeAddressAware in 32 bit Windows 7?

A;

No - LAA is not possible on 32bit Windows. You do have the 3G which, which gives applications 3GB RAM and the system 1GB (As oppose to the default 2GB/2GB). That also required you to have 4GB to make use of it. I found the 3G switch to make the system a bit flimsy and unstable.

Gaieus · 17 Jan 2011, 22:02

I also have the 3Gb switch "installed" in my boot.ini file (but I also kept the normal boot, too). I generally do not boot that way but I will make some tests if it helps with RAM-hungry operations in SU (say exporting large images with AA on).

Al Hart · 17 Jan 2011, 22:19

Thanks Gai - it would be nice to see if LAA let SketchUp grow larger for XP users who have 3GB or 4GB RAM and could make use of it.

Gaieus · 17 Jan 2011, 22:44

Al, iRender has been LAA for a while irrespective of SU running behind it, hasn't it? (Or is there a 64 bit version? I can't remember...)

Al Hart · 18 Jan 2011, 00:09

When we render, we jump out of the SketchUp process and run a stand alone .EXE, and we are able to have a 64-bit version. However, when extracting the model from SketchUp we are in the SketchUp process - running ruby code and DLLs which share the SketchUp process space. We have to be careful not to use to much RAM, because some of our clients send us models which can just barely fit in SketchUp even without loading our stuff and using it.

I think the answer to one question I am asking is "Is there something 32-bit XP users can do do let SketchUp have more address space" A by product of the answer will be that Render Plus Apps will run better on top of SketchUp as well.

The other question I am asking is "Do you have to do something to the operating to take advantage of LargeAddressAware? For all SketchUp users, that would be nice to know.

Gaieus · 18 Jan 2011, 01:36

Ah, OK, thanks, I understand the difference now. As I said, I am (also) planning to test this on my 32 bit OS (I have some pretty heavy models with over a million polys and such - even without entourage)

So, I just installed DivX and gave it a whirl, awesome, it worked so slick and the export was very fast. It looked super good.
If anyone would like to try, check out the difference between codecs like the default (I thinks it's Sorenson) and DivX. DivX is so much smoother, no where near as much jitter. http://www.divx.com/DivX

Which DivX codec: MEV, H264, AAC, AVI ?

Al Hart · 18 Jan 2011, 19:55

Regarding using LargeAddressAware on 32 bit machines.

I found out how to do this, See: LargeAddressAware Thread

Stinkie · 19 Jan 2011, 20:21

Mmm ... LAA + Vray ... Exporting large images fixed ... Looks like a useful update.

Bob,

Not entirely sure. I just downloaded the free DivX (Not the Pro) and installed the Codec Pack 1.0. I set it to export an .AVI, but I'm not sure which codec it uses. I don't believe I'm able to change what codec because I'm not using the Pro version. I hope that answers your question.

Bob James · 20 Jan 2011, 07:10

Thanks, Spence: I'll give it a try

honoluludesktop · 20 Jan 2011, 09:59

Doesn't DivX require a DivX player? Will it work with the WinMedia Player?

Pixero · 20 Jan 2011, 10:41

List of default codecs in Windows media player: http://support.microsoft.com/kb/899113

Everything else will need a special codec download.
As of DivX there is also the free Xvid. Still a codec is needed to play.

There's absolutely no difference between the free and pro versions in this case (since version 6, they can export animation exactly the same way).

If it does not work, there must be something else. To check if it does work, set the codec to something else than Cinepack. Export something (just a couple of frames) and open the export options again. If it did not change back to Cinepack, it works.

(I still like to export as image sequence better. I generally export at a double size then I batch resize them with some better antialiasing than what SU has and make the movie of the images - more control, more options, nicer output - but double/triple as much time to accomplish)

Plus, if anything goes wrong, like a crash, with images you can just continue where you left of while for a movie export you'd have to start from the beginning.

Gaieus · 20 Jan 2011, 12:06

Yes, exactly. And although not an excellent movie, this technique also allows me to use some special effects between the different parts like below.
