My first flight after SU6 and I noticed that I was getting around ~55 FPS when I normally get ~35 FPS. This flight just happened to be at night. So I fly another flight during (in-game) daytime and it was back to around ~35 FPS same exact settings. I assumed that perhaps night time was easier to render and just forgot about it… until I loaded up a flight around sunset and the FPS was back to ~55. What is weird is sunset/evening render looks closer to daytime than nighttime 
Has anyone else noticed this?
