Trees using tesselation painted with foliage cause huge performance drops
I'm getting the same issue as described in this post: https://answers.unrealengine.com/questions/190565/472-project-update-huge-performance-drop-and-bugs.html
Basically I'm using some speedtrees that have a tesselated/displaced trunk placed as foliage (With a custom shader I've done). The second I do that, I get a big performance drop. Is there a way to fix or work around this issue, or is displacement just a big no-no when using foliage?
Would adding a non-tesselated/displaced LOD1 change anything?
Not necessarily a good plan unless you have your Base LOD (using the tessellation) change to LOD1 at a very close distance. The only reason you need tessellation and displacement are for viewing a model very close to the camera to give a convincing effect. Utilizing both of these at distances where the player will not notice is a waste of CPU and GPU resources.
