Wildfire slows down

Does anyone have an answer to an unusual problem

I have recently upgraded my computer to an AMD dual core 2.4G Athlon
with 2 Gig ram and now Wildfire 2 has started giving problems.
It worked without a problem on the older computer - an ASUS with an
AMD 2.4 Gig single core with 1 Gig of ram. But I decided to upgrade,
mainly because of a bigger monitor.

I have a fairly simple assembly of a frame consisting of 27 simple
parts (square tubes and plates).
I am making changes to each part. But now when I have more than 4
parts open, the computer slows to a crawl. So slow that it is
unusable. The fifth object opened reacts slowly (rotations, moves and
zooms etc.) yet when I activate a previously opened part, it works
normally, even though I haven't closed the window with the fifth part
in. Going back to the fifth one and it doesn't work.
I have tried different combinations of opening the parts and the
problem is always with the fifth and subsequent parts. So the end
result is that I can't open more than 4 parts at the same time. This
is very inconvenient and it didn't happen with the old, single core
processor.

Asus has a utility called PC Probe II that monitors most of the
systems on the computer. The section USAGE shows me that when this is
happening, all the activity is with the CPU's. When I have four or
less windows open in Wildfire, both CPU's share the load. But when the
5th part is open and active, one CPU goes up to 100% and the other
remains around zero until I release the mouse and then both go to
zero.
This only seems to happen with Wildfire.
The voltages, temperatures and fan speeds hardly change. The changes
to the memory or Hard drive monitors is negligable.

Is there some setting that can optimize wildfire 2 for a dual core
processor?
Or does anyone have another solution?

Thanks for your input. Peter

 

Sounds familiar Do you have a drawing open at the same time as
the parts and assy? I found that slowed me down. I think it's to do
with two different ways of displaying - 3D and 2D. Now I have a second
session open with my drawing, I erase it when I have made changes in
the main session to the parts and I want to see the drawing updated.
Of course, this is pathetic and someone at PTC should be shot.

 

Graminator suggested that having a 2D drawing open at the same time
could cause it, but I only had the assembly and parts open.

Ben asked about the graphic cards and drivers.
The card on the old computer was a NVIDIA GEFORCE4 Ti4200 with a
driver 5.6.7.3 dated 4/7/2004
The card on the new computer is a NVIDEA GFORCE 7950 GT with a driver
9.1.4.7 dated 8/11/2006

Hello

It looks more a graphic card/driver problem. The behaviour is exactly the
same, as in "old days" using Nvidia GeForce 2 cards. Tweaking them to Quadro
card has resove the issue (I'm still usin one of those on my home computer
and it still working quite good (I'm using WF2). I suggest to try out some
other (older) driver for graphics card.

thanks for the reply.
I am not sure that there is an older driver for the 7950 GT and if
there is it has to run a very high resolution 30" Dell monitor. The
card has 512 meg of memory.
That was the reason that I upgraded the computer.
Besides that, the Asus system monitor is showing me that the second
core of the CPU is working great until I open a fifth window. Then it
fails but only on the fifth and subsequent windows. It comes back to
life when I either close the affected window or activate one of the
previous windows.
I have only noticed it with Wildfire but I intend to try it out with
some other programs where I can open several windows from the one
application.
