elevations and shadows

[Anonymous]

I still not very experienced in Archicad, but I allready managed to present one project in a 1/100 scale. I had no dificulties in executing all the elevations with shadows, it took a little longer to calculate but no problem.
In the project I'm working with I can't seem to do the same. by the time turn on the shadows he goes smothly to step 18 and then the preview time strats rising. I alwyas give up after 10 minutes or something! Is this normal acording to my configurations?

Thanks

What are your shadow settings? It should be fast enough with a core 2 due. The speed will depend on the size of your model, lighting, textures and shadow settings.
