Im working on project with the final Corona 8 release and my IPR maxes out at approx 50% of my Threadripper 3070X. Full render is 100% CPU and new simple test scenes are also 100%, also sometimes a fresh restart will trigger this scene in to 100% IPR usage but it will soon drop back to 50%. Tbh it feels even slower than 50% in use. There are no overrides on threads in the system options they are the default -1. I've not had this before and only noticed it in this first scene I've used with the final v8 version. Anyone else with this?
Plenty of spare RAM and its been happening since there were only a handful of mats in the scene so its not overlaidened.
