Modeling performance problems

Modeling performance problems

For small models (about 100 objects), the load of a CPU core remains under 100 percent and the graphics card is about 50 percent capacity.

The model can be rotated smoothly and you can navigate very well.

For larger models (assembly with 142020 subordinate objects); a CPU is fully utilized and the use of the graphics card falls to a maximum of 10 percent.

The model can not be rotated properly (delay of several seconds, strong jerking).

It seems that modeling doesn’t provide the graphic card with the necessary data fast enough for large models.

That With the latest hardware, CED can not retrieve the available power / capability from the new system.

This is of course a pity or an absurdity.

Here, there is an urgent need for action that the graphics engine of modeling is adapted to the modern HW / operating systems.

We have the same Problem with large models (assemblys).

We fully agree to the request of Werner Knehr.

PTC should fix that.

Yes, please fix that. It seems certainly possible to move complex 3D objects quickly today (see Unreal Engine).

We can reproduce the problem as well.
The graphics card seems to have no relevance for large assemblies.

This has strong impact to the daily work of our engineers and my expectation to PTC as the "best in class" software company is to solve this issue.

I totally agree for this improvement-request. An important requirement for frictionless engineering. PTC you know what to do ...

Performance is very important for our designers. As we have to handle also large assemblies we like to handle this request with high priority.
