Extremely slow rebuild from model in view - Intel Core 7 265K

[andrejkovac]

Hello, can somebody please solve my problem. I have fairly complex model of historical building with a lot of morphs/objects on facade. So I expect it to run a bit slow. But it is simply extreme on my Intel  Core 7 265K + 64GB RAM - which should by quite powerfull. Rebuild from model takes around 10min. I tested the same model on Ryzen 5 7600 32GB RAM and it takes only 2min and on MAC M5 16GB RAM it takes only 1min and 30sec. Is this arrow lake Intel really so bad CPU? Thanks in advance.

Operating system used: Windows 11

I have that CPU - wouldn't mind running a comparison. Otherwise I haven't noticed issues in performance.

Is that 64GB 2x32 or 4x16?

[andrejkovac]

2 x 32

Weird thing is that I ran Cinebench 2026 test and the results were very good.

So the CPU is working as expected only this specific task in archicad is problem. Every other operation in archicad is flawless.

I don't know if there are any other things that may be different between your computers that have something to do with this slowness. For example, if you Intel computer has HDD as a system drive, but the AMD computer has an SSD, that could also cause this difference.

Anyway, you could try some optimization of the geometry. You could try to speed it up by saving the most complex repeating geometries (like those Corinthian-like columns) as Library Parts and placing those instead of individual very complex Morphs. Of course, keep the original Morph on a hidden layer in case you need to modify it and resave the Library Parts. So if doing this help in any way.
