Our project is a 3d isometric game and I have been searching a way to provide player some rendering quality setting, but havent found one. Being an isometric game, the camera doesnt changes distance, and I need to force the engine to switch from high LOD to a lower one. I have tried LOD settings for MeshInstance3d (it seems to have some effect in the editor) and the Viewport LOD too, yet when I run the game, I see no noticeable gain in FPS. PErhaps Im approaching this the wrong way, or maybe Im using the wrong values. Can somebody give me a suggestion about this?
