Hi Kester,

maybe this is too technical for me. Could you please elaborate a bit more?

I think it needs some thinking how the interface should be. Because the 
target resolution is not known in most cases we nee the possibility to 
tell the camera/viewport a relative value like 30% of the resolution and 
a aspect ratio instead of pixel values.

For the user side we immediately found some interesting uses for viewports:

The scene is quite complex (34k Verts and approx. 40MB textures) and 
gains form culling very much (depending on the view direction we get 
here 30-60fps). With the additional viewport looking exactly back its 
still 30fps because now nearly everything gets rendered in every frame. 
I am quite happy with the performance.

Regards,
Carsten
