I don't have any data to support this, but it's my impression that perspective viewport performance has dramatically diminished since ... not sure. Definitely since rhino went gold.
Anybody else experiencing this?
Has anything fundamentally changed in how rhino is handling the display? Having to spend a lot of time toggling layers to keep things moving. It hasn't always been the case, and I'm working on a simpler model than previous... And getting better at keeping things lightweight.

Hi Ryan- set your display mode to defaults and see how that works- things like shadows can slow things down, as well as Skylight, by the way- that would be one thing to check, in the Lights panel. Are the mesh settings (DocumentProperties > Mesh) reasonable (try one of the defaults). I've also found that a lot of Shutlines can slow things down. Feel free to send me the model for a look.
I'm on the default shaded mode with mesh set to jagged & faster. No shutlines.
The biggest problem (related but not what I was originally asking) is when I get 3d models from vendors that are highly detailed... Which I need for rendering and sometimes for other tasks, but not for generally working with in the model. I end up making a low res version of the model on different layer... But it's a nuisance going through the model to toggle all the low detail/high detail models for render time.
This minor annoyance is compounded by the fact that linked reference mode block layers don't retain their visibility status from session to session, so when I open the model in the morning all the high res blocks become visible and I have to rummage through the layer tree switching them off before getting to work. Or, make empty "container" layers to put the block layers in as a workaround.
Ideally I'd just use linked blocks in reference mode (I have no use for active layer mode for these types of items) but reference mode just dumps everything in a pile at the bottom of the layer tree, they're all always visible when opening the file too. So that's basically not an option.
If my wildest dreams came true:
1) you would be able to position linked blocks in reference mode throughout the layer tree and they would retain their visibility status and tree position session to session.
2) you could specify two models for any given block... Use one for rendering and the other in viewports.
3) dogs could talk.
meant to say active mode block layers don't retain their visibility status.
