Black Circles, z-fighting and texture shimmering

:Shakes the thread to wake it up:
First off, thanks to everyone who has worked on this and for leading me to the fBlockMaximumDistance solution. Here's what I settled on in SkyrimPrefs.ini:
It does give my distant mountains poorer quality, but it also eliminates 90% or more of the Z-Fighting. Most everything else is set to Ultra and I get no clipping, no performance loss, and no graphical issues. There are still certain small areas in the distance that suffer from Z-Fighting, but they are now small enough and rare enough that I don't notice them unless I'm really looking for them. fSplitDistanceMult and fNearDistance were not changed. My specs:
Windows 7 PRO 64-bit
Gigabyte GTX 660 2GB (soon to be replaced with a 970 once everyone stops buying them all up...)
NVidia Driver 344.11 and all previous versions for the past year or so
Ambient Occlusion = OFF
Anisotropic Filtering = 16x
Supersample Transparency Antialiasing (SSTRAA) = 2x(supersample)
Texture Filtering = High Quality
Vertical Synchronization = ON
And more from SkyrimPrefs.ini:
I use MSAA 4X to balance quality and performance just as STEP recommends. I have Ambient Occlusion turned off because it creates little blotchy shadows and shadow flickering in odd places. SSTRAA 2X to significantly reduce the texture shimmering on plants/grass/pointy things (4x started eating my FPS). Anisotropic Filtering is shut off in SkyrimPrefs.ini so it can all be done directly through the GPU at 16x because it makes water look awesome (especially using the Pure Waters mod).
And last but not least, we now have Fences of Skyrim to fix the nasty aliasing on fences - halleluja. Now I can worry less about Skyrim giving me an epileptic seizure.

Hi, I was looking for a little help on the subject of fighting the z. I've applied Step 1 of the wiki page with the suggested fix, but not beyond the 'warning, only for very good rigs' point. My game now hangs on loading or creating a new game. I have Skyrim installed on an SSD 've waited for five minutes. I could tell from ENB 'white noise' effects on the loading screen that the game didn't crash, it just got stuck loading something indefinitely.
My specs are:
Intel Core i7-4820K, 3.7 Ghz
8 GB of CL9 RAM
200 GB Samsung SSD
Gainward Geforce 770, 2 GB VRAM, driver version 347.25
Asus GSync screen with variable refresh rate.
My overal modlist is large, but not stupendous. I use some mods that increase LOD distand lands and LOD distant object detail and additional LOD distant objects. Is there anything that can be done?

Also there are distant mountain fog textures with some enbs like vividian that help cover the z-fighting very well. The higher ugridstoload should only be used with Stable uGridsToLoad (search nexus for that). It will allow you to test higher ugrids without butchering your saves.
Using higher ugrids is not reserved anymore for top end rigs nowadays. The game is three years old, the fix is old as well. However I feel the majority of modders like to keep their ugrids standard because of save game corruption and stability issues which arise when using a lot of mods that all need to work a lot harder if more game space is forced to load.

Thanks, implementing those fixes now. They seem to help.

I don't have Z-Fighting and it's never really been an issue for me as long as I've had my computer with either graphics card.
2: Exact Video card model
3: Driver version
4: Video card control panel settings
5: In-game settings
6: ini tweaks
1: Windows 7 64bit
2: Old card: 7970ghz from Sapphire 3gb Vapor X. New card: GTX980 4gb MSI.
3: Old card: Whatever the newest driver was... The Omega drivers I was using at the time. On new card, 347.52 (basically the newest version).
4: I really don't think any tweak I made fixed it, I just sorta never had it to begin with. Current settings are from Inspector and are as follows:
Ambient Occlusion compatibility - Skyrim, Enabled, High Quality
AA - Treat Enhance as Override, Enhance, x4 MSAA, x2 SSAA for transparency
[Skyrim Launcher AA set to x2]
AS - User-defined, x16. All optimizations off. Clamp negative lod bias, High Quality.
5: Everything maxed.
6: AA off in ini. Trees receive shadows.

Im really struggling with this issue.
I have tried a variety of fixes and tweaks but none seem to make any difference.
I would be really appreciative if someone could help me out here, its ruining the game for me.
My specs are as follows:
Nvidia GeForce GTX 970
Intel Core I5-4690 @ 3.5 GHz

What is your FOV? Did you alter it any? Also, are you talking about Z-fighting or Shimmering?
Posted 27 April 2015 - 01:37 PM
Yup, the only other thing you can try is altering the tweaks upwards and downwards to see, whether the z-fighting can be improved any more on your system. Mind the fNearDistance tweak though, as it will likely cause worse clipping if your FOV is set higher as normal. See Gopher's videos TechAngel linked to for details.

torminator, have you given up on this?
I've been going crazy doing some testing with ini values all week with not much luck. I can reduce the z-fighting some, but not a whole lot.
Anyways, with the original fix, why did you settle on 4.0 for the fSplitMultDistance tweak? If you happen to remember, I'm curious. I've taken it up much higher than that (12.0) in testing and never noticed a performance issue or any real difference, but that was testing the value alone without tweaking any other settings.
I had z-fighting before, but recently it's become a monster. The fight still continues.
Just tested fSplitMultDistance=12.0 with fNearDistance=18.0... fps starts dropping even on a purely vanilla game.

I'm having a similar issue, but in Fallout 3. Is it also z-fighting? It didn't happen on my 660GTX (I now have a GTX 980 - SLI disabled because FO3 doesn't play nice with it)
Managed to make it disappear totally with "fNearDistance=15"
"fNearDistance=12" does make it disappear to some extent, but not completely.
