KLAX very hard on FPS during landing and takeoff

[swissdani]

Does somebody else have the problem that this scenery has a very big hit on the fps. For me it's the 2nd ini-scenery in msfs2024 after Dubai that has this big hit on fps. London however is just fine. When "parked" on the runway I get solid 27 to 29 fps (locked) but during high speed phases like takeoff or landing the fps drop to 3 to 5, which is unflyable. My system is pretty decent and I do not have these problems at other big airports from other developers, so there must be something with the ini-sceneries that hits the fps very hard.

 

Any ideas?
