I know this has probably been asked before, but is there a fix for distant mountains flickering? Looks like this:

this stopped happening for me a while ago, don't know what did it. It could of been when i turned off the shadows or when i changed some settings, maybe it was IMAGINATOR. My specs are in the sig btw.

while i can't tell you how to fix it (short of editing LOD meshes), I can tell you why it happens.

it's called Z-Fighting. As in, imagine having 2 sheets of paper laid on top of each other. Truck it off a few miles and look at them with a pair of binoculars on a clear day. This is basically what the rendering engine is trying to do (except with the mountain side instead of a piece of paper). It can only accurately round numbers down so far using floating point numbers (and still be a good 30-60+ fps engine), that it basically makes those two sheets of paper exist in the same space.

Then when it comes time to render the output, since those two sheets are basically in the same space, it just picks one, maybe the one that when it last rounded numbers out, one was 'closer' than the other. This is what gives you flickering like that.

It doesn't help that the LOD meshes are generally very crude, considerably lower detail than a standard mesh, but within good reason that they're only shown when the object is far off (and swapped in for a better detail mesh when you get closer).


If you really wanted to fix it at it's base issue - you'd need to rewrite Skyrim's rendering engine. Until then the best you can do is console//.ini tweaks, or perhaps some LOD Mesh mod.

Does messing with LOD bias in Nvidia CP help at all?

This may help fix this problem!
