I have an ATI as well, and after just starting the game (finally) to take some screen shots of my mod, I noticed that even some things like the Sky would disappear on some re-loads. So that answers one question: What is the color of sky in my world? Answer: I have no sky. The point - there are still a lot of things that need a 'fixin...
The problem you are seeing there is LOD flicker. LOD is short for Level of Detail, which in this game refers to long distance viewing of buildings/objects. Basically they work just fine until you zoom in, at which point they are supposed to stop being LOD textures and become standard textures (as in most other games). LOD textures are much lower quality, and they are probably not being wrapped to a mesh (though I do not know how they are implemented). I will need to test a bit more, but it is possible that they are also in the 'transition phase' from LOD to full sized texture. If that is the case, then what you see in the video is them jumping from LOD to real, and back to LOD again, in an endless loop. Once again, this is an engine problem.
I saw them flicker list night and all my LOD files were 200 - 400% larger than yours (I am testing my HiRes mod). They did this in F3 and it is part of the engine. You can max-out the LOD slider, and when that is not enough, go to TweakGuides.com and learn all about the INI file settings that you can change manually to fix a lot of problems. Most games have about 100 options that they do not give the standard user access to, and they are usually in an INI file (fallout_default.ini in this case). It is definitely not your card, and you should not RMA it. Be warned though, if you crank up the view range of LOD so that full textures are loading this will impact your FPS. If you have no FPS problems right now, then it will not be too bad. If you do, then as the other poster suggested, just try to ignore it.
