slow scrolling with new AIW Radeon 7500

[Adam White]

I just purchased a new AIW Radeon 7500 ... the boxed OEM version. I
installed it and now there are several screen display characteristics
that I find annoying and I'd like to change. I'm sure they are
related to the new AIW card, but I can't figure out how / where to
change them. Most likely, I just don't know what the settings is
called that is responsible for the particular behaviour I want to
change.

For example, scrolling in windows is slower with my new AIW card than
it was with my old card (ASUS AGP-V6600). This is evident in several
applications, and is worse in some than in others. For example, in MS
Outlook, if I am replying to an email message and I press and hold
down the <enter> key (to create several blank lines at the top of the
message), the screen is repainted each time the PC "reads" the <enter>
key being pressed. But if I enter, say, six lines the PC gets behind
and it takes a second or two to catch up (after I release the <enter>
key). The resulting screen / display is not pretty -- the entire
screen sort of "ripples" as each line of text is shifted down the
screen, and then shifted down another line, and then another ...

I KNOW this rippling was not evident before I installed this new card.
I'm guessing whatever display options are available in my OS are still
set the same (unless the AIW install changes them) and so they
wouldn't be to blame. I'm HOPING that there IS an option in the AIW
display settings that will control this ... and that the cause is not
simply this card is slower than my older one.

My old ASUS card was powered by an NVidea GeForce 256 and had a
"built-in 32 MB frame buffer, 256-bit QuadPipe rendering, AGP4X with
Fast Write, video acceleration, etc." My new AIW says "Radeon 7500,
64 MB AGP" on the box. There's no owners manual at all inside the box
(it's the OEM package).

What might be the cause of what seems to me to be slow updating of my
screen? Are there specific settings in the ATI settings screen that I
can check? I see over a dozen different tabs on this screen, but I
don't see any options that look like they are obviously to blame.

btw, My PC is running Windows 2000 (SP4) and I installed MMC 8.9
(display driver 7.991 / 6.14.10.6430)).

Thanks.

Did you completely remove the previous Detenator drivers?

Sounds to me like the hardware acceleration of your desktop isn't enabled...
I've had it happen a couple of times in XP when the new catalysts haven't
installed properly...

I would remove your current video drivers completely, reboot, then reinstall
the cats, let it reboot, then run dxdiag and perform all the 3d tests, and
see if it reports any problems there.

Hope this helps

Neil,

You are right! I uninstalled the ATI drivers (not even the other
apps, just the Display Driver) using windows control panel / remove
programs, then reinstalled the same drivers I had previously installed
.... and now my display seems fine. I haven't used it for all that
long yet, but the two main things I had noticed (hitting enter
multiple times in Outlook and also "jerky" movement of windows when
dragging them to new location on my screen) now seem fine.

I ran the dxdiag utility after my initial installation -- it did not
report any errors, but it DID say that my 3d graphics was
"unavailable." Now, after my reinstall, that message has gone away
and when I ran the 3d tests they all worked fine.

Finally, a note for those who may follow in my footsteps ... the first
clue I had that something was amiss was actually BEFORE I installed
the AIW drivers the first time! Prior to installing them, I had
uninstalled my old ASUS drivers. Well, after I rebooted (using
standard VGA driver) I got an error message from RUNDLL saying "error
loading NvCpl.dll". I figured this was some left over component that
had not been completely removed ... but I didn't worry about it. I
went ahead and installed my ATI drivers. I kept getting that RUNDLL
error message, though, each time I rebooted. I eventually removed the
NvCPL (nVidia Control Panel?) reference (and another ASUS reference
that had not been removed by either the uninstall routine or a
subsequent Norton Utility Windows check-up) using Mike Lin's Startup
Control Panel. Although I'm not sure WHY ... I think these components
must have somehow prevented the new ATI drivers from installing
correctly.

What I'd like to know is: if the ATI driver installation did not
complete succesfully, why didn't it produce an error message for
me!?!?

Anyway, thanks for your help.
Adam

THE most common Transition Problem from one brand to another is
leaving any prior driver files behind.
I swear manufactures do it on purpose. ;^) The files left always seem
to be most subtle, but detrimental to the next card.
I agree with your comment about errors while installing. Even though
the install may complete, Its rarely a good one. That goes for any
install, but especially with OS and hardware drivers. Glad it worked
out for you.
