Archicad 29 Dimension Lagging issue

[Francois Swanepoel]

Hi GS Team, I hope you can help us with this one?

Archicad 29 Dimension Tool is lagging severely, making it near impossible to get any dimensioning done and seriously delaying our work.

Any ideas what is causing it and how to fix or avoid it, please?
See this short video: 

This is currently happening on Archicad 29 Build 5003, Windows 11 on 3 x computers in the office.

I ran Open & Repair on this file several times, it says it was repaired every time nut the file still has the issue in the dimension tool.

I'll appreciate any advice / assistance with resolving this issue.

Thanks

Operating system used: Windows 25H2

I found a couple of old posts that mentions the same problem.

Here is one of them ... https://community.graphisoft.com/t5/Documentation/Lag-while-dimensioning/m-p/357193

The partial solution there was to turn of certain layers, at least then they could dimension.

So you could try that, turn off everything except what you need to dimension.

Turn other layers back on to see if you can spot what causes the issue.

However that should not be necessary.

You say you specs are OK, but I hear the fans of your machine kick in when you dimension, which make me think your machine is having to work hard.

I am assuming you are using a laptop?

If so you will have a built in video card that Archicad will try to use but is possibly not powerful enough.

Go into your Windows Display settings then Graphics settings.

Set your Archicad program to use 'High Performance' settings.

I only have Archicad 26 and Windows 10 on this old laptop but you should see something similar to this.

You could also ensure your video drivers are up to date for both the built in and dedicated video cards.

Failing that I would contact support ... https://support.graphisoft.com
