Is anyone experiencing problems when processing DWFs or PDFs through Revit 2008? We have no problems when processing drawings that do not have any shade and shadows on, but as soon as we turn shade and shadows on it can take up to an hour to process one sheet. (typically elevations and 3d views) This differs between the size of the job, but typically the file sizes are around 50-80mg. Usually complex multi storey buildings.

We are running dual core processes with 3-4gig of ram, Win XP Pro SP2, and a quadro FX3500 graphics card. We are using the dwf writer that comes with Revit and 'PDF Creator' for our PDFs

We have downloaded the latest Revit build,
We have tried adjusting the clip range on the elevations.

Does anyone have any idea how to fix this problem, because we shouldn't have to wait this long for a single sheet to process.

Any help is greatly appreciated!

Thanks
