Today I was conducting a project review of the BIM and I came across something that was having an impact on the performance of the project that I thought I would share.
Several views in the project were set to either 3/32" or 1/16" scale with a detail level set to Fine. The problem with this is that the views in question did contain and information in elements that required a Fine level of detail. Setting the level of detail to Course made an immediate impact on loading those views. So, something you might want to look at.
You might also want to consider looking at the level of detail in your families. That can be a performance killer.
Daniel Hurtubise of RevitIt has also suggested that ou also might wanna consider seting the view to coarse or medium but overwrite the display of CERTAIN elements to be fine through Visibility/Graphics.
