Windows 7: So, no WinXP Mode for me in the future.

Hi guys. I just tried XPM on my Windows 7 install. I had big hopes. Well, everything worked really good except the program I wanted to run in XPM : Adobe Audition 1.5.

The bug I had directly in Windows 7 is obviously gone coz it's running in WinXP. But the thing that made me go "No, XPM is banned for me" is the fact that the software LAGS LIKE HELL. The playing cursor does not follow correctly the waveform and when I click "Stop", it stops around 5 seconds later.

I know that Virtual Machines are limited in 3D application and such but this software barely needs 2D graphics that every Virtual Machine has right?



Don't blame my specs, coz my machine is really enough to run XPM.

Sorry you've experienced a let down. Spec wise yes, you're fine, but you are running the bare minimum for RAM (2GB) to use XPM and it is not the speediest set out there running at a fairly low clock (for today's standards.) The CPU is almost 3 years old now as well. I'm not denigrating your machine specs as they are very likely in the average window for the most common machines out there right now and are well within Windows 7 minimum specs (but we know the specs are higher for XPM of course.)

However, I would wonder more about the Adobe application you were using. How does it run in XP? Is it somewhat slow there as well? My experience with a number of Adobe applications (Reader, Acrobat, Photoshop, Premiere, After Effects) is that they are somewhat piggish as they are needing gobs of RAM and CPU in stand alone installs, much less a virtualized environment. They are also not known for their immediate compatibility with non-standard scenarios and I think XPM qualifies. How do other applications run in XPM on your machine?

I imagine that tweaks will be made to XPM to speed things up as it has just been released to the masses. The test base will be a bit smaller and may take more time but they've done a great job with Windows 7 so far so I have high hopes they'll do more here as well.

This post sheds some light on the subject as well...

Thx for replying. Gonna give you rep.

Adobe Audition (including the ancestor, Cool Edit Pro) is working like a dream on XP : every audio professionals or amateur prefers by far XP for audio needs because Microsoft ditched the audio in Vista (and Seven isn't great either) mainly because you can both Stereo Mix and Record from a Mic at the same time on XP and you cannot on Vista and Seven.

Perfs wise, it's not lagging at all except v2 and up where you need those to make it not lag :
- old 2D graphic card
- HUGE amount of RAM.

That's why I still use 1.5. Anyway.

Also, I've try it with 768MB of RAM on XPM and it still lag. I will try to put it to the max I can put : 1500MB of RAM on XPM at home this evening.

I haven't tried anything else on XPM but I may try Nero 6 on it (simply the best Nero EVER).

Ah, thanks!

I hope that adding more RAM to the VM will help. It should but it may not be enough until you upgrade the hardware in the future. It will be interesting to see how Nero works.

I've not taken the XPM plunge yet but I will soon. It's a pretty cool concept.

um at this point its not the 3d thats giving you the lag but the emulated sound card
(sound blaster 16 if i remember correctly)...
all the DSP processing (which happens in the Sound chip) is now happening on the CPU which is very inefficient...
hell even playback of a sound file takes about 35% of Cpu power in the least...
imagine running a DAW?
also i believe you installed Asio drivers (have less lantency than the regular driver)
and with all VM software all audio emulated is not useful for DAW usage...

Asio drivers? I have an on-board Realtek. I didn't check if the XP drivers were installed. I'll check this up. I'll keep you informed tonight.

I read this in the installation document that Microsoft released which may or may not be related to your issue but it sounds like it could be:

I wonder if installing a PCI sound card and making it the default card for the VPC is something that can be done to help in this case... worth looking into.

sorry but at this point all vm software all emulate HW execpt maybe usb (hybrid emulation since VPC installs a generic driver when you insert a usb into the VM...)
if you had a low latency usb sound card then maybe it might work..
but apart from the rest is emulated....
and thus cannot be changed...

OW... I thought I could run Adobe Audition 1.5 without losing Aero or having that pointing problem anymore with XPM . BUT! I'll try Nero 6 on it It needs some audio stuff but it's nothing to be afraid of. I only want to create Data and audio CDs.

Do sound editing and capturing in Virtual Machine is not very good idea.

It simply because a virtual machine have high DPC lentancy. Whatever the power of the host machine is.

DPC is the ability to make or play in real time multimedia stuff.

In the fac DPC lentendy vary from hardware.

You can see DPC lentancy of my computer in first picture and from my virtual machine on second.
