i'm sure that this issue was addressed with the release of a new set of dll's for IL-2. do a search for dll's, you'll probably find it. there was a d/l floating about here with 5 different sets of dll's in it. if you can find it, try to use those, and see what happens. the more recent ones, i'm sure, did address this issue with some systems.
having a look at your specs, i'm wondering why you don't run it in 1600x1200? - you're doing yourself an injustice running in the lower-res.
one thing you could change in your conf, is the LandGeom=2 setting, in the Render_OpenGL part. Try this with a 3 value, for much improved visibility distances.
Good luck in getting it sorted.

Nah. Sorry to say that, but 4.09DLL,s and 1C DLL,s didn't adress this issue. It's present in coastlines and shorelines, over all at low altitude. You can test the five DLL,s launched, and you will see the effect stays.

The only way I got to eliminate this effect was with supersampling antialiasing through Nhancer (you cannot select this sort of AA through the Nvidia driver control panel, it's only Multisampling). But with SSAA (x16SSAA, for example) the most of rigs fall at their knees.

I live with it.

My rig:

- C2D E8400 @ 4.0Ghz.
- 2*2Gb GSKILL @ 1066Mhz
- Gigabyte X48 DS4
- Nvidia GTX295 @ 675/2100
- Audigy SE
- TX 750 Corsair
