Ventura and Archicad 26 very slow

[g r a n t]

Hi....

I am NOT an IT specialist....so I may have made some mistakes when installing AC26 and Ventura. Last Fall I installed AC26 on the previous macOS. Then a week or two ago I upgraded to Ventura. 

After upgrading I noticed that switching between plan and 3D views on the models there is significant lag time before the model updates. I did not have such a lag in the past.

I re-read the installation notes and Graphisoft notes to first install Ventura then install AC26. My AC26 was already on the machine. Could this lack of recommended installation sequence be a cause of delay?

Thanks,

Have you installed the silicon build of Archicad 26? That will get over the recommendation of installing AC after upgrading to Ventura as it’s a completely different application and it offers significant performance improvements on the M series processors.

Hi, Yes. 4024 Int Full (Apple Silicone). That's why I'm finding it funny to have such a lag switching between plans and the model while the model updates. The models are fairly simple houses. Files were 25 but upgraded to 26. Thanks. Grant
