In-Game Performance

The first set of tests compare a level made with normal static meshes, the same but using the foliage mode, and with one using instances created with rdInst. Note that the instances created with rdInst are “Managed” so come with a slightly higher setup cost than a simple unmanaged instanced system.

The Foliage in these tests are from the MegaScans library and have all been converted to Nanite. They’re using between 1K and 4K textures and have complex meshes – in line with the next gen requirements.

Empty Scene for Comparison – 114 FPS
Using standard Static Meshes – 72,300 meshes (30 different) – 32 FPS
Using the Foliage Tool – 72,300 instances of 30 different meshes – 106FPS
rdInst generated – 72,300 instances of 30 different meshes – 107FPS
rdInst generated, Unmanaged – 72,300 instances of 30 different meshes – 101FPS
