I have been experiencing an issue where performance drops significantly if I am looking at an actor, close up, with LODs and dithered LOD transition option turned on (in the material). The closer I am to the actor, the more significant performance drop is.
I don’t believe performance drop happens during one LOD transitioning into another, but when base LOD is being rendered and camera is really close to it.
If I turn off that option in the material, I have no performance drop at all.
Any idea if it’s a bug or if I am doing something wrong ?
