This add-on automatically toggles an object’s visibility setting based on its current visibility in the viewport. This helps optimize viewport performance. The main focus is to improve viewport performance in solid view during 3D navigation. This add-on supports Blender 3.0 and above (it may be compatible on older versions but not guaranteed).
This is a spiritual "sequel" of my nView add-on, I’m so excited to release this for free and open source!
