Terrain lag

[Alienhead]

I can create a new scene with 2 cubes on it, one cube as a large floor and another cube as a player.  I get about 1100fps.

If I create a new scene with a 512x512 terrain on it, no textures. just a flat terrain and a cube for the player i get about 118fps..

Something aint right !

Can you maybe confirm if FPS only drop if Tesselation and Terrain shadows are enabled?

See also my bug report here:

I have tess turned off plus I dont even have a texture on the terrain.

Have you got a navmesh with debugging turned on? I noticed that gives quite a hit to your performance.

Im starting to wonder if it could be the shafting AMD drivers release... but I doubt it.

I have an NVIDIA 3090 GPU,  So if it's the same, its not about the driver. And I also don't have any navmesh
