Grey lines/patches in mid-air

[MightyCrow]

Can anyone help me with this weird issue? Basically I have grey lines/patches usually in the sky that are quite large. All the rest of the game is fine just the sky is covered by grey patches. Sometimes these grey patches are near the ground as well. I thought it might be missing textures but I'm not sure. The sky is fine it seems to be in between the ground and the sky. It also seems to only appear when viewing from a certain angle, like I can look one way and it's perfectly fine. I have a decent laptop which plays Fallout NV on Ultra: i3 CPU, ATI Mobility Radeon HD 5165, 4GB DDR3 RAM, Win7 64-bit.

 

I followed the instructions carefully and spent the whole day installing mods so would rather not re install. I am quite sure I didn't make any mistakes, also I didn't do the optimization. I did most of the reccommended INI tweaks in the guide and most mods especially the big texture ones I chose the FPS versions. Any ideas?

Can you provide a screenshot of what you are seeing?

I have also noticed that the ground textures are very messy. They look like 2 low res textures combined into one. This leads me to believe it is to do with the textures.

That specific screen looks like it used to do in Oblivion when 2 mods conflicted that added changes to that specific landscape (not changes to the textures that is, but actual changes to the landscape) but with different land-height. Not sure if that's very likely if you usually have it happen up in the sky though...

Actually I thought that at first, but on close inspection it can happen anywhere in the world. Like I can see patches really close to the ground, or high in the sky. It looks like the textures are stretched really far. Here is another pic I uploaded. Yesterday I found a tree where the top of it stretched really far into the sky but I couldn't find it today.

I will say that I have not tried the game on a clean install yet. I got the game yesterday and immediately started installing the mods from the STEP. I will not re install just yet but if I can't solve this that is what I will do.

Ok so I found this thread:

It talks about a possible solution by changing something in the ini related to grass and trees. This has worked for me but at the expense of the former not looking very good. It is to do with my Laptop ATI graphics card so I am going to try and update the drivers and see if that works.

FIXED: I installed new graphics drivers and the issue is completely gone.

I actually had that happen to me once, it was caused by deadly dragons and another mod interacting that I never was able to trace. It begs the questions are you running deadly dragons?
