Viewport: 160 fps rotating, tumbling and zooming but 2 fps playing a camera movement

[Roodogg]

Hi guys. Really weird problem here...

 

I have a brand new scene with an imported revit model.

 

Manipulating the viewport is silky smooth at 160fps, but creating a camera and playing it's movement is horribly jerky - I can see the timeline jumping rather than moving along.

 

I have no materials / mat editor is closed. edges off etc - although I know viewport performance is fine anyway at 160fps!

 

Any ideas? Thanks in advance.

Find some CLEAR NOTES scripts, like cleaner 8 on scriptspot, and some DWG cleaner.

Did you import via simple import, or via linking?

Also, maybe find some here
