Need help in figuring out parts getting visually corrupted

[DT_10814054]

1) I have had a problem where the parts and sometimes assemblies get visually "corrupted". If it happens in parts it is still doable to work around it If I ignore it, as only the visual image gets distorted but I can still work with the part as normal (I can rotate, extrude, and everything normally). Things get tricky when a whole assembly starts to act this way, and I cant really ignore it.

I suspect that is occurs the most when I open a part from the assembly and start working with it, but I am not very sure why. 

I am not very knowledgeable of computers but these are my laptop specifications:

processor: 11th Gen Intel(R) Core(TM) i5-1135G7 2.40GHz 2.42 GHz

RAM: 16.0 GB

Graphics: Intel(R) Iris(R) Xe Graphics

Creo: Creo Parametric ver9

2)Another college of mine has a problem where Creo straight up just crashes and closes when it becomes a little heavy. The most we do is drawings and assemblies and it crashes for him. We rarely do simulations.  We suspect that it is because his low memory, but if there is a known reason for this it would be great to know.

CPU: Core i5-10210U 1.6GHz SSD:256GB

Memory: 8GB

Graphics: Intel UHD graphics

Thankyou in advance.

Hi,

my suggestion ... add following option at the end of config.pro file temporarily and test Creo behaviour.

graphics win32_gdi

If Creo behaves "decent" during the test, then you can try installing a different version of the graphics card driver.

Note: Both computers are equipped with Intel integrated graphic card. Usually users work with computers equipped with dedicated NVIDIA graphic card.

Martin most likely has the correct response here, but just to expand on that a bit:

PTC tests and certifies PCs (specifically graphics cards and drivers) to work and then publishes those known to work. Not all graphics cards are created equal and it is known that gaming graphics cards do not work well for CAD software. Hardware support is published here:

https://support.ptc.com/partners/hardware/current/support.htm 

Most likely the issue is not the underlying geometry of your parts, but merely the way that it is getting rendered on your screen. I say merely but in some cases poor graphics cards and or drivers can cause the software to crash and or be so slow that it is impossible to use the software.

Hi,

Ill write a little update, and a question at the end I'd like someone's opinion about.

Thank you for the suggestion, I followed them and tried using Creo normally for a few days.

As per the original problem, I have not been getting the "visual corruption" that I originally had, but I noticed a few other things.
Dimensions in drawing blink when moving the drawing. When I move my screen all the dimensions disappear and reappear very fast, making this very fast blinking effect when I move the drawing around.
Everything is just slower. Not dramatically but enough to annoy you a little when first trying it out (adding the option to the config.pro file).
They are not terrible overall , and with some time you could get used to.

We were thinking of using something like this when using Creo to compensate for things. Is it a good idea?

Hi,

when graphics win32_gdi option is included in config.pro, Creo graphic is slow and blinking. That's how it should be. The option is only intended to test whether the problem is related to the graphics card drivers.

Your test confirmed that the problem is related to the graphics card drivers. So remove graphics win32_gdi option from config.pro and try installing different version of graphics card drivers.

Example: My notebook is equipped with Intel UHD Graphics 620 and graphics card drivers version is 31.0.101.2125. In the past version 27.20.100.9466 was installed.

Regarding ADLINK, use of this external graphics is at your own risk. It is not supported by PTC.
