Thanks GS - that is a very interesting suggestion and very helpful research!
After a bit of a struggle was able to update the GPU firmware (noting that neither the Gigabyte Control Centre firmware update function method nor the manual bios update executable method actually work by default with Gigabyte RTX GPU firmware updates - a long standing issue apparently. A workaround for anyone interested is posted here)
A couple of motherboard BIOS settings needed to change as well, but end result is Resizable Bar is now active.
While still slow, this time same settings did not time out completely on lowest resolution image in High Vram mode, but they still do time out on highest resolution in high Vram mode - even using minimum iterations settings (20)
In low VRAM mode, while still slow (still maybe a minute or two), it is noticeably faster with 20 iterations, on highest listed resolution (1216x832).
In low VRAM mode, with highest resolution, and highest available iterations (50), image generation does complete, and takes around 3.5 minutes
That said, while I can see the AI is riffing with the scanned shapes from ArchiCAD and applying its large catalogue of statistical patterns related to images of buildings, the lack of any innate understanding of how a building works is pretty evident.
This is still far from being useful as a design tool, and you would never want to show the results to a client, however nicely rendered - the basic and obvious mistakes might well get them questioning your fees.
Essentially this is generating a stylistic composition that has a superficial resemblance to a building without really reflecting any spatial organizational substance or functional purpose - the exact opposite of the actual architectural design process we are paid to undertake.
We are not short of much more coherent glossy magazine images already if we are just looking for inspiration
Lower prompt strength seems to generate slightly more plausible results (assuming you have enough of the critical elements resolved and modelled yourself).
But prompt strength set to the minimum 25%, gives results that are still far from usable
And of course having the critical elements modelled already then brings in to question the need for AI at all at that point, except to the extent I guess that you could create the impression of having done more modelling entourage work than you actually have.
But the minute the client asks you to extend a bedroom while leaving everything else as is, or to show you the floor plan corresponding to the image, the whole thing is exposed as fake, since without a resolved underlying model with 1:1 relationship to the image, these things can't (yet) be done, as far as I can tell.
I suspect the real value of AI as a design tool would kick in when AI can generate 3D models reflecting some insight as to the way buildings actually work - though hopefully (from a gainful employment point of view) that moment will not arrive too soon!
