Material reflection : THE FPS killer on big airports?

Hi Guys,

I have a big FPS losses on CDG despite a comfortable configuration (RTX3080 + Ryzen 3900X + 32 GB RAM). It’s quite astonishing but I lose 20 FPS in some places on the ground on the airport:

15 FPS

39 FPS

17 FPS

37 FPS

(Taken in drone mode, with 320Neo, ultra setting and 4K RES)

I have the impression that these FPS drops are mainly from the reflection of glass buildings. Exemple : Terminal 2 are use a lot of glass.

Do you see the same thing?

What is weird is I also get 15 fps above LFPG, and I have a much lower machine than you (GTX 1070 + Intel 4770).

Looks like there is a problem with LFPG, I just tested other heavy airports in big cities like JFK and LAX and i get 30 FPS. Only at CDG i get 17 FPS.

At JFK and LAX I am “limited by mainthread” while at CDG I am “limited by GPU”. I think there is a problem with some buildings.

I have no other problem with the simulator

Yes i did too
