Archicad 28 home screen delay

[Takis]

Hello everyone,

I'm experiencing a long delay in the HOME SCREEN menu when opening Archicad 28 and when deleting recent projects.

The same delay also occurs when I open the HOME SCREEN while working on a project.

Is anyone else facing these issues?

Archicad 28.0.2 Int.

Intel(R) Core(TM) i9-10900X CPU @ 3.70GHz 3.70 GHz

32.0 GB (31.7 GB usable)

NVIDIA RTX A4000

Windows 11 Pro

Eduardo, yours is fast!

Mine is even slower than yours, so I have a very, very long list of recent files!

Just spent the last 30 min cleaning the Recent File list and after only leaving only one in the list the time from launch to selecting the file is down to 11 seconds.

@Eduardo Rolon thanks to trying and confirming. I will enter a high priority bug in our database to fix this.

The problem with slow start screen has been around for quite a while for me since AC24, especially after a huge module publish, most likely due to the recent open files list. To clear it quickly I always close all AC and delete the "Recent Documents (Project).prf" and "Recent Documents (Symbol).prf" under:

C:\Users\user_name\AppData\Roaming\Graphisoft\ARCHICAD 26.0.0 XXX R1\

or

~/Library/Preferences/GRAPHISOFT/AC 26.0.0 XXX v1

and it should be instantly quick afterward. I guess it still applies to AC28

Dear Minh,

Thanks for your help. I deleted those two files from the folder you mentioned, and now everything is working fine.

For now, it seems that the issue is caused by the "Recent Files List."

I'm not saying the problem is fully resolved yet—I’ll monitor it for a few days to see how it performs.

Best,

Takis

I am not sure that it is the recent file list itself that is the problem.

I suspect it has something to do with the preview (symbol) files that are saved for each file in that list.

Just a hunch on my part.

But keeping the recent file list to a minimum in all versions with the start/home screen seems to help.

Barry.

I've had no such  an issue with the earlier version of AC (27)  on the same local machine, which is my only 2 yrs old and the most powerful 27" iMac ! So it is definitelly not about the machine and it is about AC 28. Please consider this option first. I have the same problems as all the  participant in this conversation have mentioned above and it is new since upgraded to AC 28.

Same.  AC28 seems to be a bit sluggish compared to AC27. Maybe due to all the new "animated" tutorials.  Even when disabling all of these it still feels slower than AC27

Good morning, I am also experiencing a slowdown issue on the Archicad 28 startup screen. The macOS spinning wheel appears when loading the most recent files, which are stored on the local disk of the computer. Additionally, there are slowdowns when loading the sample projects hosted on the web. The most annoying part is the slowdown when launching the software and selecting recent files to start Archicad.

My setup is a Mac Studio M2 Max with 32GB of RAM, a 1Gbps Ethernet internet connection, connected to a 27” Studio Display monitor with a 5K Retina resolution.
