I'm interested to hear others experience with Revit 2012 & 3D performance. I've got an GeForce 9800 GTX+ and tried both the autodesk 'certified' drivers and newest drivers. In general navigating perspective views is a little slower than 2011. The most noticeable lag is with ambient shadows on. When starting the walk command there is about a half second delay before you start moving. A half second doesn't sound like much but the result is that you 'jump' after the delay if you've moved the mouse at all. It makes it difficult to use the walk tool with ambient shadows turned on.

Revit 2012 & 3D performance...

We just built a new system in office that is using the new i7 2600, 8 GB DDR3 1333 and an nVidia GTS450. Hasn't been any issues using 3D with this setup. However, the new changes to the 3D engine in Revit did bump up the requirements on the video side a little bit compared to 2010 and 2011. Our older C2Quad machines do experience a slight lag as they are running GTS250 graphics cards. The lag is less than 1/4 second though.

If anyone else is experiencing this issue I described with camera view and ambient shadows, I encourage you to submit a support request. So far mine is the only report they have and they don't seem to be able to reproduce the issue. If they have more reports/more data, it may help them solve the issue.

Since my original post I've upgraded to a faster computer with faster video card (GTX 560 Ti) and I don't really notice any performance issues with the relatively small models I work with. I do still have the specific issue I detailed regarding navigating a perspective view with ambient shadows on (the delay before movement begins). But I also use a Space Navigator now and I don't see the issue with the Space Navigator.
