The following results were all taken with a stationary camera, deferred rendering and at 1080p resolution. The prefab instancing results are from the included PrefabInstancingDemo scene and detail instancing results are from the DetailInstancingDemo scene. All shadows are calculated with 4 cascade, soft shadows.
To test instance rendering only, the rigidbody components were removed, particle effects were disabled and shadows casting is off. All instances have colliders on them except the 500k (Unity max collider limit is 262143). There are 3 asteroid prefabs with two LODs each. Average LOD0 mesh has 750 tris and average LOD1 mesh is 100 tris. The table shows average FPS values for incremental asteroid instance counts. For testing Without GPUI, the Enable GPU Instancing option is enabled on the materials.

The scene has a total of 552.383 vegetation instances and 23 types of vegetation (4 grass textures and 19 plant prefabs - 2 with LOD groups). The results were taken with the first-person camera while stationary. Without GPUI results are default Unity terrain values.
