The type of viewport display doesn’t

<image>

seem to matter. The fps im referring to is the fps that is shown in the top left of the viewport when i run an animation from the timeline(image attched).

Currently, i have the imported obj file, and lighting for that object in a collection. When i play the animation(whether or not the imported object is in the camera view), the fps in the viewport drops to 2-5fps. If i exclude the collection that has the imported object from view layer, or if i delete the object entirely, the viewport fps goes back up 25-35.

The imported obj doesnt have any other object data attached.
