I use ArchiCAD 9 Build 2045 USA FULL on Tiger 10.4.1.
I am not sure if this is something that just started happening, if it started with the upgrade to Tiger or the if the latest upgrade to ArchiCAD which came out a few weeks ago triggered it, but I experience what I consider to be extremely slow user interface performance. Basically what happens is whenever I change tools or select an object of a different type the interface freezes for a second. I tracked the problem down to the Info Box. What I think is happening is that the info box is redrawing info for the newly selected tool and it takes a second to calculate it. With info box closed I have little or no user interface lag. I have my info box at default width but at going down entire length of left side of my screen. Yes, it is large but it is the same setup I used with ArchiCAD 8.1.0 v2 (2284) with no UI lag. In ArchiCAD 8.1 info box changes almost instantaneously. Now one second doesn't sound like a lot of time but I find myself waiting for the UI almost every time I want to perform a command and it is really annoying and unproductive. I am working on a project in 8.1 and some other projects in 9.0 right now and it seems like I work much slower in 9 because of it.
I use a Dual 2.5 GHz G5 w/ 2.5 GB Ram and a NVIDIA GeForce 6800 Ultra DDL graphics card so I am pretty sure that my Hardware is not to blame (plus 8.1 works great). What have other people's experiences been running ArchiCAD 9? Is anybody else experiencing what I am talking about? If this is some kind of display bug Graphisoft needs to fix it right away, if it is not then I don't know what to say.
P.S. - Also have major IU lag in object viewer; sometime is can take several seconds to update preview window when new object is selected.
