I'm working on a big scene. From one point I noticed a drastic change in the viewport performance. To find out what was draining FPS I tried to exclude every collection from the layer and all the fancy staff from the viewport, ending with still low FPS, and really nothing happening.
Where can I look to solve this problem?
The scenes are linked duplicate, each one with just one render layer. If I try to deactivate ALL the collection from ALL the layer nothing changes. (Also tried to turn off the world shading setting)
What I'm wondering the most is:
Witch is the workflow to debug low FPS situation? Am I correct assuming that the disabled collection shouldn't be evaluated?
