Archicad 28 home screen delay

Takis — Tue, 11 Feb 2025 14:19:38 GMT

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

Still not liking that window and I agree it is extremely slow.

IMO after using AC for 20+ years I don't need to see sample projects…

Hi all,

We do know of an issue that is causing performance problems with web-based content across remote desktop connections.
Can you confirm if this is the case here or is the slowness present on your local machine?

Any pattern could help us to address this issue.

Thanks in advance,

Zoltán V.

It is on my local machine.

Unacceptably slow on launch in local machine connected directly to router with average dl speed of 500Mbs.

The pattern is simple:

Close AC
Launch AC and wait for 1-2 min until the screen opens
If AC opens it usually takes between 15-30 seconds.

I really Hate-HATE this screen and I hate it more every time I need to launch 27…

@Eduardo Rolon the "27" was just a typo hopefully, since there is no home-screen in AC27 🙂

I am really interested in getting to the bottom of this issue, since we do not experience this kind of problems and nor did we receive similar reports through other channels. So any input here is valuable to me: screen recording of the problem, display specifications, storage type info (hdd or ssd), recent list content, anything.

Feel free to reach out to me directly in direct message or email, so we can work on this together.

No typo.

The startup screen in 27 is much better than 28. I can launch 27 and select a previous file in under 8 seconds.

AC 28 takes 45.

So every time I open AC27 I am reminded of the slowness of 28.

IIRC I reported this during the Beta and at a minimum I posted this 4 months ago.

Archicad (28 in particular) certainly likes to be installed on the main SSD drive.

I had it installed on a second HDD as I was low on space, and it was much slower.

Re-installed on SSD and much faster.

But I have noticed it seems slows down over time - I am sure it is not just my imagination.

I think it is an accumulation of preference files and recent files and sometimes auto-save files in our user profiles that are not being cleared automatically.

I don't use 28 as my main Archicad, so have not really investigated anything.

Certainly in 25, 26 & 27, the recent list of files seems to slow the start screen.

I always try to clear the old ones when I know I don't need them any more.

I would happily go back to just having 8 or 12 most recent files as it was pre start screen.

Barry.

Every time I click on the recent list to remove old items it beachballs between 30-45 seconds. So clearing up the oldest 10 items takes between 5 to 10 minutes.

If I switch to another Tab I have to wait to switch back it doesn't come to the front since it is beach balling in the background.

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\

~/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.

robbyrobbyrobby — Fri, 07 Mar 2025 06:38:19 GMT

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.

Thanks for this! The home screen was getting ridiculous for me. Graphisoft should really come up with a solution to this, maybe allowing you to customise a limit to recent projects or something along these lines.
