Graphics display issue

[howiep]

Hi,

I recently upgraded from CreoElements to Creo 2. I have a
machine with a non-OpenGL graphics card, which I realise
is a no-no, but it worked flawlessly with CreoElements,
and subsequent versions. The actual card is an ATI Radeon
mobility 5165.

The problem is when I open an assembly, or open a new
window from an assembly, about 1/3 of the screen has a
crasy motion-blur effect. See the image below. Sometimes
that area is also black and doesn't refresh. It varies.


I have found a work-around, but it requires me to do it
every time I open a new part/assembly. What I do is go
into the 'entity display' menu, and change the anti-
aliasing settings. The strange thing is that it doesn't
matter what you set them to, or even if you set it back
to what it was when you started up. The mere act of
changing the setting temporarily fixes the issue.

I called the tech support our distributor offers, but he
wasn't able to find a solution. Changing the cofig
'use_software_opengl' to 'yes' did get rid of the issue,
but it also made the display freeze whenever a feature
was pre-highligted, so that's not really a useable fix. I
assume the problem there is that the card is not OpenGL
capable.

Anyway, I know I need to upgrade to a more suitable
machine (it is on the cards in 6 months maybe) but for
now it's really frustrating to know it's capable of
displaying perfectly, except for this little issue.

Any words of wisdom would be thoroughly appreciated!

Cheers,

Other options to try are:

graphics win32_gdi

or

graphics d3d

And see what you get.

If possible, try to get a low-end OpenGL workstation
card. The low end ones can be had pretty cheap (and may
be some used ones on eBay, etc.).

Had a similar problem when switching to Creo 2.0. Went to ebay and searched for nvida quadro. Purchased a used one FX3000 and this solved the problem.

Thanks guys. Tried both config options. Both fix the
original issue, but win32_gdi causes problems with the
pre-selection highlighting (takes ages to refresh). d3d
fixes the problem, but the pre-selection is still a bit
laggy and awkward. I'll try it out for a while and see if
it's better.

Upgrading the GPU isn't an option because I'm using a
laptop unfortunately .

Thanks again!

I had a similar problem that was corrected by setting the antialiasing control in the graphics card control panelto be controlled by the application.


Creo has a place to control anti-aliasing in the options menu in the entity display section.

try updating your graphics card driver
