Hi Brian,
It's all or none. Though I didn't spend any time figuring out what a value of
would do ;-)

No worries Rick, I didn't think you were heavy at all, instead you raised good
points.
The reg key you have mentioned below, does that stop all visual effects for all
applications running in this shell?
thanks for your help.

Hi Brian,
Sorry, came on a bit heavy.
There's nothing intrinsically wrong with the XP interface, except for
the huge waste involved in supporting visual effects. Get a really old machine
and run XP on it with My Computer > properties > advanced > performance set to
either best appearance or best performance. Where CPU is limited, it makes a
huge difference to the perception of speed.
However there's nothing wrong with the XP user interface once
animations are disabled.
Just include the following unmanaged policy snippet in your TS policy
templates, disable visual effects and you can have the best of both worlds.
--------------------------
CLASS USER
CATEGORY "Visual Effects"
KEYNAME
"Software\Microsoft\Windows\CurrentVersion\Explorer\VisualEffects"
POLICY "Visual Effects"
PART "Disable Visual Effects" CHECKBOX
VALUENAME "VisualFXSetting"
VALUEOFF NUMERIC 0
VALUEON NUMERIC 2
END PART
END POLICY
END CATEGORY ; visual effects
-----------------------
regards,
Rick

Hi Brian,
Calling the XP interface a "rich" user interface is actually
quite correct. It costs a lot more and aside from making things pretty, adds
nothing to the functionality of the base item. Efficient and functional is
beautiful too.
[Lilley, Brian] very true indeed.
There are 2 good reasons for not even considering running any
of the special effects on terminal services. The first is an increased CPU
overhead and the second a significant bandwidth utilization increase. ANY
animation, be it fades or whatever has an overhead and across a WAN will
produce a perceived reduction in performance. Updating bitmaps takes cpu,
bandwidth and time.
[Lilley, Brian] I totally agree, that a TS design should cut
out unnecessary flashy gizmos, but, at the same time we can't remain with
legacy look and feel. Is the XP look and feel really going to cost that much?
Log in via a WAN connection, use Excel, enable "feedback with
animation" and insert a column in a spreadsheet. Now do it with "feedback wih
animation" turned off. Which one's better?
[Lilley, Brian] I totally agree.
Users will complain a lot less about a plain user interface
than they will if it's slow.
[Lilley, Brian] Absolutely, however will the XP look and feel
cost that much?
The latest client, with MPS 3.0 does support other skins for
seamless apps, but that overhead is largely borne at the client end so doesn't
have a significant effect on performance.
[Lilley, Brian] ah, ok... so does that mean we can have XP look
and feel at little cost.

Rick

hi list,
I understand that the XP theme is not available by default on
windows 2003
servers. I assume this is because you don't need a rich user
interface on a
server. Ok, well if that server is a terminal server then you
do potentially
want that rich interface (for well connected ICA/RDP clients).
So, my question is this, does anyone know the level of overhead
required for
the XP look and feel relative to the classic stylie? I guess
the overhead
here is two fold, firstly, one CPU overhead to render rounded
corners and
other XP 'stuff'... and the other overhead is in transmitting
this down an ICA
channel, i.e. does it actually require additional bandwidth.
Also, what would happen with transparent windowy bits I
understand the win32
client released with FR3 for xp included support for LUNA
(.net) seamless
apps, although ... I've never tried it...
any thoughts on the subject appreciated...
Brianos :o)
