clipping graphics in corners - see through land

No matter how I set up my ini or in game settings, I cannot eliminate the missing polygons that appear in the corners of the screen when I move the mouse around. It is not all the time, and it is most pronounced on hills and mountains, where I can see through them entirely.

Also, hills in the distance at times will be missing until I get reasonably close to them, then the game will pause for a 2-3 seconds and load the missing polygons.

No amount of ini modding has fixed this problem. All other games run flawless.

This shouldn't happen. The graphics should be correct, apart from a couple of minor clipping errors here and there. Especially on such mainstream hardware everything should be fine.

The only thing that come to mind are the 2 standard answers "reinstall the game" and "check for driver updates".

Found the problem.
Installed a different graphics driver but that wasn't it.

It is the DistanceHigh.fFarClippingPlane_High variable in the ge3.ini. I had mine set too high causing the glitch.. mine was at 20,000.
I thought I tried all settings but I must of never lowered this all the way back to stock.

Now I have to ask, is there anyway to increase this variable without the glitch?
The stock setting looks HORRIBLE.
The ground in front of the character is a blurry mess, and a distinct LINE where the textures are improved. It looks bloody awful…. default on high is 10,000 and it's just not far enough away. Thanks

These must be set to the same value in the ini.
Render.PrefetchGridCellSize and
DistanceHigh.fFarClippingPlane_High

Render.PrefetchGridCellSize defaults at 10,000 so anything higher will cause the glitch.

I can now set them to:
Render.PrefetchGridCellSize 25000
DistanceHigh.fFarClippingPlane_High 25000

works amazing!
