performance ini A330 Entering MCDU Route Info Causes Low FPS (Longhaul Routes Only!) (w/Video showing the issue)

[VTCHFX]

As you can see in the Youtube video that I have uploaded, I start configuring the plane. 

I show in the video:

Longhaul route info being entered -> frame drops

Shorthaul route info being entered -> little frame impact

Longhaul route info being entered with other destination -> frame drops

I could imagine this is some kind of memory issue. As of now I will make a longhaul flight without entering the arrival runway yet. I will fill the runway info as soon as I reach the Top of Descend and see if the issue still persists.
