FSX-MS What causes this to happen in FSX?

[AS129 - Michael Johnson 9]

I have the Imaginesim KATL scenery for FSX.  Does anyone know why this and most of the other add-on sceneries do this?

I have a pretty good system running with a Nvidia GTX 3070 Ti.

Did you have any other KATL scenery installed before adding the Imaginesim KATL?

I'd suspect you're running into memory (VAS) issues--missing textures, including ground textures, is a classic symptom.

Fresh install of FSX.  Just the default KATL scenery.

Sorry, I should have pointed out that the effect is only momentary.  After a few seconds all the scenery fills in and looks normal.

Could be the CPU is not processing the data fast enough.  Your graphics card is more than enough for FSX, but what CPU is in your computer?

No, don't think it is the CPU.  Unless... hyperthreading can sometimes cause a performance decrease.  Have you disabled hyperthreading?
