I am experiencing severe viewport lag and navigation difficulty when using the OctaneBlender Addon 30.9.1 with Blender 4.5.3. The issue occurs with heavy scenes that were created in the stable, non-addon Octane 30.7
The lag persists regardless of whether the scene has been properly converted

Yeah. Pretty much unusable in 30.9 but nice and smooth in 30.7 CB. Also scene compilation takes quite a bit longer in the addon.

Just adding that this isn’t only happening with heavy scenes. Even small, simple scenes have the same issue. The UI becomes very unresponsive, selecting objects and moving around the viewport all lag heavily. It basically becomes unusable

Something's definitely off here. On it.
It looks like we have some kind of problem with geometry nodes.
