That's more of a side effect than anything. And it's not like the presence of NTVDM on your box lowered performance or anything.


It doesn't really work any better than the x86 version for that (unless you wanna try running x64 compiles). I'm perfectly happy with Vista x86 for that (and VS2008 is perhaps the app I spend the most time in)


That's a reason in itself to have waited some more. There isn't a x64 version yet (it's due for next year), and meanwhile running PS under WOW64, adding extra overhead, doesn't make much sense either. And once it's out, it just might need new x64 versions of your plugins and such too. Adobe themselves last time said there was no point going with a x64 version, because it wouldn't have helped at all (it's memory bound, and x64 doesn't make memory access any faster). You're only going to get some benefits, when you work on a few GB worth of images at once (100+ megapixel HDR pano shots? ) And again, most people will need to buy more RAM for it to make use of it in the first place.


Yes, I totally agree there. They seriously have to. Windows 7 shouldn't even come in a x86 version. It's not like anyone's going to run it on an old P4 or an Athlon XP, and by then 8GB of RAM will be quite cheap and getting close to mainstream.

I have been scouring Google and have not seen one single reference to Excel taking more CPU cycles to do calculations under a 64-bit OS. Can you provide me with some links?


You want an H.264 video in an MKV container? You got it. Screenshot attached. Vista x64, WMP11 64-bit.
"[Minori-Osu!] Zero no Tsukaima - Princess no Rondo - 01 (h264 848x480) [9EA0CE55].mkv"

I have also been scouring Google for any references to unsatisfactory playback of HD content in Vista x64, but have been unable to find anything.

Quickest ref to find, by Stéphane Rodriguez, is on the "OOXML is defective by design" blog here. He's a specialist in the subject matter, and he's documented the excel 2007 format extensively as you can see here. Again, it's just one example, to show WOW64 does add extra overhead.


Well, perhaps you're using different codecs instead of CoreAVC and the Haali splitter (or running those under WOW64) but again that's not exactly optimal (higher resource usage for sure).

It may be a side effect of the 64bit architecture, but the removal of the 16bit subsystem is a good thing. It's that much less legacy code that needs to be supported and less code problems to deal with on MSFTs part. The more legacy code that is removed from Windows the better. Instead of maintaining legacy code for old apps, they [MSFT] can put more effort into other aspects of Windows.


It does when you need to build 64bit binaries and need access to larger sets of RAM.


I didn't need to wait longer. I needed/wanted 64bit now, not later. When 64bit versions of my favorite programs comes along, I will already have the capability to take advantage of them. I like to future proof my PC parts purchases for at least a little while.


By that time (hopefully), with Nehalem, memory configurations of at least 12GB will be (somewhat) common. I have 8GB in my box now and sometimes it does get constrained a bit. DDR3 prices will be dropping sometime mid next year.


I use CorAVC and Haali, Xvid, QT and others almost on a daily basis under 64bit XP. Absolutely no problems whatsoever. Video playback in XP64 is a lot smoother than in 32bit XP.

In the link you provide, there is neither any reference to 64-bit nor "defective" as a word, so I'm not sure what I'm supposed to be looking at. It's a lot of code from an 18 month old article.


The player, when running that video, uses about 46MB of RAM. It uses 64-bit codecs provided from the x64 components pack, a codec pack that's been posted on these very forums since it's creation. WMP11 64-bit can't use 32-bit codecs, WOW64 or otherwise.

Crahak : 8gb ddr2 IS mainstream, maybe not in your country but everyone i know, has at least 4gb, and generally around 8gb is the norm.
I'm upgrading to 16GB once i can get hold of a decent 4x4gb set, should be out some next month hopefully.

8GB ddr3 however, wont be mainstream before early next year most likely.

Canada. And ~95% of new PCs sold nowadays only come with 2GB, for most of North America, and likely a lot of European countries too. 4GB is just barely starting to be what I'd call "mainstream" (there still isn't much "normal" people with that much RAM in their PCs)

The number of desktops I've seen so far with 8GB? Zero (and I see LOTS of PCs...) It's not anywhere near "the norm".

8GB might be mainstream among PC gamers, but that's a tiny minority of "enthusiasts".

hmm... i just downgraded from Vista x64 to XP x86 SP3. what i got was MUCH FASTER SPEEDS but abt 1 day into using it, i got a common problem i seem to always have sooner or later, when i start XP, sometimes it lags (maybe cos i clicked something too fast or what). when i go to task manager, i see that under the Username column, its blank! so it seems like explorer got corrupt or something... looks like its true that XP is faster but less stable. i always liked XP for its speed and Vista for its looks. but i nv thought Vista was actually more stable...

thinking of getting a Mac, but i just saw Apple's site and it seems "Snow Leopard" will be out soon? so i think i will go back to Vista for now?

xp.sp2 doesn't have these problems

i think there is... i searched around google i think last time, and learnt that its due to explorer.exe being corrupt i think

Hi to all.

We actually work (video editing) with an Athlon64 3700+ / 2Gb RAM / 2 x 500 Raid0 machine with Windows XP SP3 32bits.

We've buyed 5 x Canon HF100 and we have some problems to manage all FXP (1920 x 1080, 17 Mbit/s) streams together (multicamera edit).

We work with Sony Vegas that is 64bit compatible since the version 8 so, do you think that the switch to xp64 may help ?

Thanks in advice !
