Zoom Delay after update to Creo Elements/Direct Modeling 20.7

CS_9662297 — Mon, 28 Apr 2025 07:36:45 GMT

Hello,

i've done an update from Creo Elements/Direct Modeling 20.2 to Creo Elements/Direct Modeling 20.7.1.1.

Now the same assemblies are very slow in zooming and have sometimes a delay in movement.

I use WIN10 Pro, HP Z4 G4 Workstation with Nivdia Quadro P2000 and 2x16GB DDR4 RAM. Can i make any settings or hardware upgrade to make the programm as fast as it was with V20.2? Or should i install a version beetween V20.2 and V20.7 with more functions than V20.2 but comparable speed?

BR, Chris

Take a look - "Highly delayed zoom when zooming in and out frequently in Creo Elements/Direct Modeling Annotation": https://www.ptc.com/de/support/article/cs328535

Hello VladimirN,

thx for fast response, but the linked articel doesn't help to solve the problem. I updated from also V20.2 ...

windows has it's own (weired?) stragety to assign a high end graphic card to a process running!

Are you sure that the GPU is doing the job and not the CPU? ==>> the Task manager has a tab to show performance of different major components. When zooming / panning the 3D view port the GPU should get under load, not the CPU.

What is the situation on your system?

AFAIK you can assign the Nivdia Quadro P2000 to the process soliddesigner.exe using a Nivdia tool ("optimization" / "performance" .. )
Or you can disable the build in graphic card at all, AFAIR in the system's BIOS.

Both ways are already described.

So it might be by installing Modeling 20.7 Windows was doing the wrong guess (maybe it will be diced)

Hello Wolfgang,

thx for the hint of task manager performance... i saw, that the GPU is doing the job, if i zoom in/out.

Then i tried out to load the old version V20.2 ... and now the same slow speed zooming occured!

I remembered, that i had an error at opening new views in modeling after first installing V20.7.

"Fehler bei Aktion create_vp/signal/sigsegv"

I found a solution in the cad.de forum by setting an environment variable in the win system:

Name der Variablen: SDPIXELFORMAT
Wert der Variablen: SOFTWARE

After this the failure disappeared .... but after this zooming got slow.

Then I tried to erase the variable again, and V20.2 was fast, as it was before ... and what a WONDER: Also V20.7 functions now without problem and is also fast 🙂

Thx too all, who tried to help me!

SDPIXELFORMAT= Software is really the very last choice and a compatibility test only IMHO. Every thing what (even 15 year old) CPUs+ GPUs can do in hardware for graphic display is done in Software on the CPU (may be in a single thread) There fore it is slow, SLOW, SLOW.

Have there been a graphic driver update in the same time period?

Well, why SETTING and UN-SETTING the environment variable should solve the problem . Uhhh . that's magic and not understandable. (IMHO).

Any way. Keep your system as it it and let's keep the fingers crossed in addition.

Thanks for the feedback!

One Hint @ all . : better try to keep your old version of a software for some weeks to be able to compare old and new version's behaviour.. Well, if the specific setup.exe does allow parallel installations (which is not that common nowadays)

Perhaps the "View" failure occured only directly after 1st installation of V20.7, ...without new system start beetween.

Now V20.7 runs stabile and fast 😉
