Problem with Asus9800XT and Archicad 8.0/8.1

Anonymous

Dear Archicad user,

My computer was running very smooth and fine until recently, that i was working on a 64mb hotel file based on 8.0 r2. It's a pretty complex and detailed model.

2d plans, sections and elevations were fine when i generate them.
The main problem is to generate 3D window. It took me 45 minutes to generate 3d windows. not photorendering yet.
the setting of 3d setting on 8.1: openGL.
rotating the model in 3d windows looked fine. but that's after 45mins!!! to generate it. Faster rotating speed compared to my last nvidia Ti 4200.
photorendering in 8.1 r1 took about 5 minutes.

Need help and advices for those who uses ati vga card, and their experience dealing with big files.

i doubt it's the problem with the openGL setting on ati card.

Kindly post your advice.
Thanks.

Perhaps you are using exceptionally complex elements. Roof tiles and balusters are often big contributors to the complexity of the model.

You might be able to reduce some complexity in these sort of parts to help speed things up.

Post a screen shot or two so we can see what you are working on.

Thanks for reply Matthew, you can find the screen shot on:

the elevation and all exterior works remained the same, only some internal elevations of rooms were changed. i dont think it affect the 3d model generating time.

one more thing: this project was created on the same system except the graphics card, it's a nvidia Ti4200@128mb.
the graphics card was upgraded to 9800xt 4 mths back.
it took about 2-3 min to generate 3d model on ti4200, on the other way round, 45min on 9800xt@256mb. this is what bothers me.

Please advice. Thanks.

ATI is at fault.

I also have ATIs at home and at work, both by mistake but ... Yes, the regeneration is QUITE slow, after that all is well. nVidias I used always had MUCH faster model generation time.

IMHO!

Your model does not look especially complex. It sound like Djordje has your answer. I am not having any speed problems on my PowerBook but it has the NVidia GeForce 4.

Hmee, well,

Thanks for the reply Djordje, i guess we can conclude that ATI is the major cause for the big slow down in the 3d generation of archicad model.
Agreed???

'sign' , not very worthwhile after invested on ati's high end graphics cards huh!

Any good recommendation from the new nvidia's?

Thanks.
