FSX and FS9 problem

Hi

I bought a new computer

asus p6t 6gb ram
i7 930
nvidia9800gtx
i use win 7 64 bit

i have very good frames, an average in Madrid barajas with all at maximun of 30 frames

the problem that i have is that the scenaries in the distance seems like blurries. i have photorealist scenery installed
in fs9 i have the same problem. i use nhancer but no results.is like if the textures were moving
in the other hand i have a 32 inches monitor. the problem is that when i choose a resolution bigger than 1024 the screen gets like green

what can i do?

1024 res max ... try re-installing the latest graphics drivers http://www.nvidia.com/object/winxp_197.45_whql.html
That should fix that problem.
As for the textures it could be harddrive speed. Give her a defrag. Failing that I'm not too sure with that one.
Also, turn DX10 preview OFF in the menu, not sure which one exactly
