Noticed today, that Win7PE_SE despite having all drivers installed, delivers a really poor performance for audio and video.
So i ran it on an older machine (Celeron D 3,2GHz) to better accentuate the difference and the performance is abysmal compared to a real Win7.
100% CPU usage to play a mp3 file, on the above computer.

Can anyone confirm or report the opposite?

[MedEvil]

Strangly Taskmanager itself consumes a lot of CPU cycles too, if open, but drops back to normal values when minimized.

Anyone an idea, why this happens?

comodo is either picking up allot of false positives or viruses since when I ran it it found 3 viruses in this build, in the shell and config and hiderun_x86.exe reported virus warnings. these files came from vistpe and imported into this newer build,I might run it through virustotal.

false positive. you can find the full source code for hiderun under C:\[your winbuilder dir]\Projects\Tools\Win7PE_SE\src

ok thanks for letting me know,it was over looked by me

Playing mp3 320kbps with VLC 1.1.11, cpu usage is between 2 and 4% here.
Playing an avi-movie 1932kbps the cpu usage is between 15 and 20% here.

The VLC media player script is here:
http://reboot.pro/15...268#entry133268

The above is from a win7pe with directx & audio scripts enabled…


Ps. Using this hardware:
MoBo: GA-MA78LM-S2H
Cpu: AMD Athlon II X3 425 (rana) 2712.2 MHz
Chip: AMD 780G / SB700
Ram: 3072 MB
Gpu: ATI Radeon 3000

In "real" machine (xp) cpu usage = 0-3% playing the above media files.

Thanks for the test al_jo.

As far as i can tell, there's something internally not properly working in Win7PESE. Therefore it does not work as efficiently as a real Win7.

Ran a few dependency scans and it doesn't seem to be related to missing files.

On faster computers it is no problem, when the media player produces around twice the CPU load in Win7PESE as in a real Win7. On slower ones it can be.

There seems to be a problem in the grphics subsystem.

When i move a window like taskmanager fast across the desktop in a swirling fashion, there is no and should not be any 'trail' draged behind, with DirecX and graphics driver installed.
However, if i open a explorer window and then do the same, the area of the explorer window retains the trail images until i stop. Only then it is redrawn. This should not be happening. The redraw should be instantanious.

Any ideas on, how to pinpoint the root of the problem?

yes, exactly that is my experience, too

I noticed the same types of issues like MedEvil has. I have directx and display drivers being installed and this happens both on laptop and my PC. Not sure where the hangup is but its definitely a weird occurrence.

Edit: Ive even had video issues playing youtube videos in opera and internet explorer. So definitely not a browser problem.

This is a DirectX problem in all Win7PE. For some reason, background (re)drawings are not DirectX accelerated, even with DirectX and graphics driver installed.

This creates some spectacular effects in certain programs. Yet, not spectacular enough, for me to keep this feature!

Unfortunately the old and informative Dxdiag was replaced with a useless version, which does not only not offer any details, but also states that everythings works perfect, when it clearly doesn't.

btw. mp3 playing with XMPlay in Win7PE up to 3% CPU usage. In NaughtyPE without DirectX 0% all the way.

Hi MedEvil

i use this modded win7pe_se based on 'Win7PE_SE_2011_07_22' project,
using x86 RTM(SP0) Ultimate en-US source
for me - on real hardware - seems there is no so horrible problem with audiovideo, youtube etc.
i attached a .log file, too
just to see what scripts were used/disabled.

these scripts mainly originated in the time of yahook's original Win7PE or Joshua's RescuePE - so maybe now not everything needed, and only this bunch of scripts will increase really the size of your PE - and not the display2.script He-He!


Regards,
dera

[MedEvil]

How am i to use the scripts in the archive? Simply add them to an existing 'Win7PE_SE_2011_07_22'?

[dera]

Yes
+
just disable the original equivalent scripts that come with the original package
according to the attached log.html
(i mean
hotplug <> z_own\hotplug
display <> z_own\display2
BitLocker <> z_own\bitlocker
Drivers\Audio <> z_own\audio\audio_w7_v5)

Your script pack includes a script named "add for wmp". You wouldn't have to have the wmp script that belongs to that?

[MedEvil]

Dera, i think i might misunderstood you.
Your initial post gave me the idea, that those scripts would greatly increase the size of the wim.
Instead they made it even a bit smaller.

The Hotplug script works actually a bit worst, than the one included in Win7PE_SE.
Besides that, i didn't really notice any difference in functionality. Though the network tray icon was nice.

[MedEvil]

There seem to be a bunch of troubles actually. USB behaves unpredictably. Sometimes refreshing the explorer view on first insertion of a stick, even the one that didn't work before, the next time not even refreshing the view, when the good working one is used.
Sometimes sticks can be pluged in and out multiple times, without explorer starting to work properly.

USB-Audio is included in the default Audio script, not in the Hotplug.script or your audio.scripts. So i had no sound anymore.

Networking script is useless as far as i see. Without Penetwork, it is not able to make a connection.

The benefit of the cpl script also escapes me. Yes there are a few more icons in control center, however a new working one, i couldn't find.

Hi

Currently my main problem is the search script,
in the past (with previous versions of win7pe_se) it worked,
but now it doesn't.

Hi MedEvil

my hobby is feedle with PE.
so these scripts mostly originated in the past (VistaPE, RescuePE era),
i created them not for the public just only for myself,

the 'adds_for_wmp' script itself is the 'Windows Media Player' script

dera

I understand that. I was just surprised, that things didn't work for me, since you said, you use them yourself.

Yes, thank you. Figured that later out too, but forgot to post.
The script integrates WMP really nicely into WIn7PE_SE. However it seems to break the ability to switch users.

[MedEvil]

Don't know, if your problem with the search script might be the same as mine.
I miss the reg files the script wants to merge.

Hi

seems you are right
sorry for this!
(probably i confused my test projects)

yes, i use them in a Win7PE_SE_2011_02_10 based test build
and for me those scripts work
(e.g. the screenshots in post #9)

[MedEvil]

Ok, i still have a Win7PE_SE_2011_02_10.

Like i said, WMP is working great. Starts fast, no first run wizard. So far the best i tested, in any Win7 project.

I just wished, that Winbuilder wouldn't require the makeDir command.
Would be really great, if a single script could be run against an empty Target folder, to compare the files two similar scripts copy.

Maybe its just an "english" issue, but I am not clear on what makeDir has to do with comparing things? Are you looking to compare their "results" or the actual scripts? How "similar" are the scripts? Maybe if you tell us more of what you want to achieve (instead of how), someone would write a tool to do that.

For me, I always use tools like WinMerge (which can compare files in a fairly intelligent manner) or wingrep to llok for specifics in files, etc. That is usually enough for me to track down what is changing and to manage the "changes"...

[MedEvil]

For instance, when i try to compare the 'adds for wmp' script from dera with the 'WMP 12' script from Ludovici. I'm out of luck. Though both scripts aim to provide the same functionality, they can't be compared scriptwise.
They both use completely differnt commands, not to mention, that one copies single files, while the other copies a few times complete folders.

The only way to compare such two script, is in my experience to compare the results. Which ... requires to create the complete folder structure in Target beforehand, since WB does not create folders on the fly when a copy command demands a non existing folder.
