Here's my problem:

 

I have added airport textures (runways, apron, etc) and grass replacement textures that work fine and display well as can be seen in the first shot. I am also using UTX Europe at highest resolution with no problems.

 

However at some airports, e.g. EDDF the airport area looks really ugly, see 2nd shot. These textures also show in mountainous areas.

 

I have installed summer textures by Aimé Leclercq but that didn't solve the problem. My scenery settings are fairly high and detail textures are activated.

 

Does anybody know how to fix this?

 

 

 

 

 

My settings:

 

 

 

 

 

 

This is how FSX 'blend' different ground texture together if I am correct.

Does it mean it can't be fixed?

Since you have an nVidia gpu have you tried nvidiaInspector?

Yes, I've set it up as recommended in the Tips and tricks section. All areas look fine apart from the examples above. What setting in the inspector could affect it?

some discussion here:
