ArchiCad 17 Performance

[Anonymous]

We've been 'playing' with AC17 for about a week now and the general consensus in the office is that it is more 'clunky' and 'sticky' to work with than AC16. I have migrated a large project from AC16 to 17 and it is noticeably slower and jerky, especially when navigating in 3D.

I thought AC17 was suppose to have performance enhancements?!

Thanks Karl, I didn't mean to hijack the thread, but...

Disabling the "Textures" checkbox seems to be the key. This means I give up the ability to see siding, etc. but that's fine for my usual editing in 3D.

Your solution was much cheaper than the new MacBook Airs and Pros I was looking at!

Free is good. 🙂 Glad it helped!

Martin-
Have you checked to see if there is an update on the video card? You seem to be running a newer iMac so I am surprised if you have problems. Mine is only two months old and it is working great. What other symptoms are you having???

Martin,

Have you gone to the Apple menu > Software Update... to assure that there are no firmware or other updates for your card from Apple?

If so, then it might be an issue related to your being on 10.6.8?? Don't know. But, Apple includes newer graphics drivers in the newer releases of the OS. (Of course, leaving 10.6.8 would mean leaving Rosetta and your ability to run old PPC software. So, if that is the issue, you'd want to create a complete bootable clone of your OS so that you could reboot into 10.6.8 in the future to run old software including ArchiCAD versions prior to 10.)

Perhaps post in the Hardware forum a request for other Mac people with the 5750 to report if they have the issue you're seeing.

The common experience seems to be that 17 is faster. It seems snappier to me but I haven't opened one of my monster projects yet.

A Xeon with 12GB and a Quaddro should be good enough. Hard to say what the problem is.

Would you regard this as a monster project?
