This has started to happen to me across multiple versions of AC (our office uses 22-25). I was able to record this for AC 24 but it is persistent in those I have tested. Additionally, if a change is made to the view settings of the 3D window, it will jump to the last active 2D window almost like it is trying to regen.
To squash any questioning replies: yes my drivers are up to date, all system updates are in place, and all peripherals are updated as well.
This was not always the case for this specific computer, but we are in the process of testing how Windows 11 works with ArchiCAD as commercial sales are ending for Win 10 and support is dwindling across multiple platforms. This did start happening with the Win 11 upgrade but according to Graphisoft, they are supporting AC versions 25 and up for the Win 11 transition. It is unacceptable to have graphical lag impact performance and efficiency.
Has there been any fix for this? Are there even any constructive thoughts from GS? Has anyone heard anything other "update your drivers" from GS?
Any help would be greatly appreciated.
I had exactly the same issue and I had a hard time concentrating.
I finally solved it by uninstalling Archicad, but using iobit uninstaller.
The difference with uninstalling from windows settings is that iobit uninstaller erases everything, including registry records of the application.
I installed it again and it works great.
