When I create a new level and add the lighting actors, my FPS hit 180. However, as soon as I import a landscape from a heightmap, no matter the landscape size, it plummets to 90/100 FPS. It’s getting very frustrating.
Any settings I should fiddle with?
Working with UE 5.2, I don’t know if it’s the same with 5.1.
No landscape
4K heightmap
8K heightmap:
10k heightmap
Actually, with a 10k heightmap, it seems to be a little better 
Hi FatsAndRoses,
You really can’t tell the true FPS impact of your landscape until you package it and check the framerate from there. The editor is rendering a lot of edit features, plus maintaining all the GUI.
Also, with UE5 I’ve noticed that my base projects with just landscape do run slower than older versions, but adding the foliage, roads and assets etc doesn’t take as much of a hit - it’s like some of that time is being used to optimize larger numbers of meshes/nanite etc.
Hi @RecourseDesign,
that’s a fair point. I’ll pack everything (with LODs etc.) and check it out.
Thanks.
