fomr
realtime. Its I have a ADM 3200+ with 2 gig of ram and a x700 256mb pci-e
and
it causeing totaly lag all over my system... DWM and explore whe dwm,exe
is
on hihg spikes the cpu at 70%
so I want MS to realse a patch to fix
this
so that itwill start at normal = 8 so I don;t have to maual set it to
normal
on ever restart.
What exactly is lagging? You do know what DWM IS right? What it does?
There's a reason it's set to high,

Desktop Window Manager
In Windows XP and earlier operating systems, applications draw their
graphics directly on the screen asynchronously, which occasionally leads to
inconsistent displays. In order to eliminate some of the issues generated in
this scenario, Windows Vista includes a Desktop Window Manager (DWM). The
DWM is effectively a Direct-3D application that controls the display and
update of windows on the desktop by aggregating screen content (sometimes
called compositing), and then drawing it as a finished image on the user's
display.
DWM brings two primary enhancements to Windows Vista, both enabled through
WDDM. One of them is an overall improvement in quality, and the other is a
signature user experience, called Windows Aero.
As mentioned earlier, Windows XP applications update the screen directly,
and this happens asynchronously with respect to the monitor's refresh rate.
Having multiple applications update the same screen in close proximity can
result in the user seeing windows tearing, or occasional images that appear
incorrectly or slowly. By drawing the entire image from one place, DWM
eliminates both issues, giving a very high quality desktop experience. The
user has a much leaner experience, and a more responsive system.
Windows Aero is Windows Vista's highest performing desktop experience. The
DWM makes the experience possible, and requires a machine with appropriate
graphics, including WDDM support, and one of the appropriate Windows Vista
product editions. Aero features include Live taskbar thumbnails for running
applications, DPI scaling, Windows Flip and Flip 3D, and the transparent
glass design on the displayed windows on the desktop. Aero gives the user an
outstanding user experience, putting a stylish effect on the UI of any
application, and is particularly complimentary with Windows Presentation
Foundation applications.

This gives screen updates priority over most other processes on the system,
and remember, how fast and smooth the images are rendered is usually how one
judges (really, perceives) how fast and smooth their machine is running.
Frankly, I'm puzzled since my machine isn't lagging (3 GHz P4 HT with 1G
RAM) at all, and I usually have a few memory and CPU hogging applications
running at once.
Setting the priority of DWM to "Normal" actually seems to slow down my
machine a bit, by that I'm citing noticeable lag when dragging windows
around, using Flip 3D, etc.
Something is wrong with your system (have you updated the video drivers?)
I've never seen DWM go any higher than 12% on my system, and that was moving
Media Player around the screen with a video playing, so if yours is peaking
at 70% or more, the DWM is working a lot harder than it should have to.
Oh, one more thing I'd like to point out . . .
DEMANDING patches in a primarily user to user help group is going to get you
exactly nothing.
