ALandscape::ActorLineTraceSingle(…) very very very slow.

params sample:

pLandscape->ActorLineTraceSingle(
	hit, 
	posite + FVector(0.0f, 0.0f, capsule.GetCapsuleHalfHeight()*2.0f), 
	posite, 
	ECollisionChannel::ECC_WorldStatic, 
	FCollisionObjectQueryParams::AllStaticObjects);

And GetWorld()->SweepSingle(…) ignoring Landscapes.

Hey-

Another user posted an issue with ActorLinetraceSingle() here ([4.7.3] Actor::ActorLineTraceSingle doesn't work correctly in the editor - Programming & Scripting - Epic Developer Community Forums) which has already been reported as UE-13362 for investigation.

Cheers
