Slow viewport during paused IPR

Hello,
why does my c4d viewport fps drops below 1 when IPR has been paused? this makes pause function of IPR useless as it clogs viewport for some reason.

I am on Mac

c4d is totally clogged, I don't even make any changes except of wanting to move around viewport camera.

since you mentioned scene size I found out it does not happen on smaller scene and on my bigger scene I noticed If I delete ASS objects it works smooth, so it is ASSes that must clog the viewport even with IPR paused.

Maybe it is linked to generally bad viewport performance of ASSes we talked about already.

Yes, sounds likely.

that is once again pity as good proxy objects are a key render engine feature, I hope those issues will be addressed soon rather than later as I would hate to start a new project with all geometry baked into the scene file.

The plugin still collects scene changes while the IPR is paused but no actual scene update takes place, so it should not slow down the viewport. I'll take a look if I can reproduce it. How heavy is your scene and what changes do you make which slows down the viewport?
