performance compared to the ArchiCAD version from 22-27

[Antoni]

Hi everyone,

I'm reaching out to seek some advice and insights regarding a performance issue we're experiencing with Archicad. Our team has been working on a project for some time now, and we've noticed a significant slowdown in performance, particularly in Archicad versions 22 and 23.

We initially thought the problem might be due to our hardware, so we tested the project on different, more powerful computers. However, there was no noticeable improvement in performance. Surprisingly, when we opened the same project in the Archicad 26 demo version, it ran much smoother.

I have a couple of questions:

1. Are there any known limitations in Archicad versions 22 and 23 that could be causing these performance issues, which might not be resolved by simply upgrading hardware? 
2. Can anyone confirm that each new version of Archicad, including versions 24, 25, and 26, has brought performance improvements regardless of the hardware used?
   
   We have tested a file on intel I7 4790 32gb ddr3, Ryzen 3900x 64gb ddr4, and 13950hx with 32 GB ddr5. 
   Our file weight about 1,5 GB which is caused probably by a large number of saved views, sheets and apartment cards and also linked DWG file and Hotlinks. 

Any insights or suggestions would be greatly appreciated. We're trying to determine the best course of action to improve our workflow efficiency.

Thanks in advance!

Best regards,

Speaking from our experience as we were mostly doing our projects in AC24 there appeared to be quite a bit of slowdown with subsequent updates to OS. Even though we are on Mac once files taken from AC24 to AC27 (and AC27 perfectly moved libraries across) speed improvement was about 3 times faster. Again this was just our experience and you might want to make a copy of that project and open with latest version available to you for comparison. Maybe our speed increase was due to AC27 being compiled for Apple Silicone but looking at your configurations they all seem to be quite capable even with 1.5 GB file.
