This thread will never die ;-) Thanks for your input! However the method you use is already known and comes with a great decrease of the visual quality of the distant terrain. But you're right, that's one way to do it. Some rigs can't even run high blockdistance settings, so those guys never get z-fighting at all. As for my chivalrous promise to still keep working on improving my fix, I have to say, that the absolute finetuning is so specific for different rigs, there is nothing I can really tell you guys as guidance how to make it better on your setup. Just use one or multiple of the methods floating around, and tweak them yourself as long as you want. Cheerios Torminater

:Shakes the thread to wake it up:

Hey guys,

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:

[TerrainManager]
fBlockMaximumDistance=70000.0000
fBlockLevel1Distance=70000.0000
fBlockLevel0Distance=35000.0000
fTreeLoadDistance=70000.0000

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
AMD FX-8350
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:

[Display]
bFXAAEnabled=0
iMultiSample=4
iMaxAnisotropy=0

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.

Hey sevencardz glad you found your preferred settings . This thread is never dead or necro, so don't think that it's odd to post here after a while. As you also found out its still not possible to get rid of all the z-fighting without losing too much quality. There might still be hope, when new tools that create better matching lods appear on the net. There are such developments although we don't know how much it will improve upon the flickering issues. Thanks for your input!

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?

You should use the skyrim memory fix in SKSE with 512 MB. There is a rather extensive thread on these boards about this. Sheson is the author of the fix.
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.

 

1: OS
2: Exact Video card model
3: Driver version
4: Video card control panel settings
5: In-game settings
6: ini tweaks
7: mods
8: dxdiag
 
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.
iBlurDeferredShadowMask=10[/size]
fInteriorShadowDistance=3000.0000[/size]
fShadowDistance=3000.0000[/size]
iShadowMapResolutionSecondary=2048[/size]
iShadowMapResolutionPrimary=2048[/size]
iShadowSplitCount=3[/size]
fShadowLODStartFade=200.0000[/size]
iShadowMode=3[/size]
bTreesReceiveShadows=1[/size]
bDrawLandShadows=0[/size]
bShadowMaskZPrepass=1[/size]
iShadowMapResolution=2048[/size]
fShadowBiasScale=0.3500[/size]
iShadowMaskQuarter=4[/size]
iShadowFilter=4[/size]

What is your FOV? Did you alter it any? Also, are you talking about Z-fighting or Shimmering?

If you've tried all the tricks there's nothing much more you can do about it. Check out Gophers video 1 and video 2 about it. I would also highly suggest this mod to help hide it on the mountains.

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.

 

Edit: disregard

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"

 

However that makes the first person weapon clip, no matter what fov chosen.  pinch.gif

 

"fNearDistance=12" does make it disappear to some extent, but not completely.
