Fs9 Cruising Horizon

Dear Simmers

I'm having difficulties in having the right mix with REX about the horizon at cruising level.

These pics are taken at FL 380. As you can see it's not very clear and I used to fly in better conditions however after a clean installation of fs and by changing the sky textures in REX it didn't help me, as whatever I chose the sky horizon is always the same.

Also attached you will see my AS Evo visibility settings

Any help?

Thanks

Justin
