I reinstalled the whole simulator an it got even worse. I tried flying on default scenery and nothing is loading, Not that they take long to load, no they even don't want to load. My sliders are on max and my settings on the AMD Control Center are all on default. I haven't touched my my fsx.CFG file yet. It's not the first time I have reinstalled fsx but this is the first time that this happens..

 

Do you mean once you have been flying or they don't load even from the start

 

Also, try with your sliders not on max. It's a good start

No they even don't load from the start. It's the same thing if I put sliders in the middle or else where
