Thanks for the update, I'll play around with those settings. As for creating a video, you could try Cam Studio, or get an eval of Fraps.

Ok, so I've been making a video but because of unknown reasons I didn't get the black circles as bad as before. maybe I'll have to disable 3d again.- just did that and ... NO CHANGES! What the hell? kind a weird, and I didn't change any drivers. well my girlfriend killed my system by pulling my keyboard out of my tower whilst trying to create a playlist. so i had to hardreset the BIOS and voilĂ  all the problems seem to have decreased (not only relatively):- z-fighting decreased
- water-bug by SLI decreased. only minor abnormalities left
- black-circles close to INEXISTANT
I'm absolutely baffled. Just looked up if there had been some sort of new patch for skyrim but so far... nothing.
No clue but I do like it a lot ;-)
So different setup:
beta-drivers
HD-DLC& BethHiResOptimized(https://skyrim.nexus...ile.php?id=9957)
ultra-settings
Nvidia-settings
SLI active, 3D active
fshadowbiasscale=1.5
fSplitDistanceMult=5.0000
Let's see.
Min FPS=60
z-fighting LOD only: pretty strong
z-fighting mid-distance: very few seconds until new textures popup automatically.
shadows seem to move when moving towards them, they get lighter at midday. I don't know what's causing it but so far that's the only new problem I discovered (might have been there before.)
Wow. Found the sweet spot for testing z-fighting for LOD.
Just around Helgen. Looks awful ;-)
By the way: z-fighting causes longdistance-clouds to blink madly. So this tweak doesn't really help at all. you may decide if you want dark blinking or white blinking xD

I'm going to start testing again by changing one parameter at the time until z-fighting seems to be the least disturbing.

Z-Fighting-Elimination-Crusade

What I will try to do is the following:
Z-fighting became a far greater nuisance with the beta-patch for me. Don't ask me why, but that's the way it is...
This is how I will try to get rid of z-fighting without loss of graphic quality (if possible):

Setting:
- Skyrim 1.5.26.05
- Launcher by SKSE
- near Helgen (Screenshot will be added.)
- daytime: afternoon 2 pm.
- viewing the mountain range behind the lake (strongest z-fighting for me EVER)

Nvidia-Drivers:
- Download the 5 latest drivers for my graphics-card: incl. latest beta, the 4 newest WHQL-certified versions: 280.26, 285.62, 295.73, 296.10, 301.24.
- Check where there is the least z-fighting.
- Not used: 3D, SLI, Nvidia-tweaks, HD-DLC, Mods, ini-tweaks and on Ultra-Settings only.

NVidia-CP:
- SLI activation: +/-?
- 3D activation (hiding effects): +/-
- Not used: Nvidia-tweaks, HD-DLC, Mods, ini-tweaks and on Ultra-Settings only.

Nvidia Inspector:
- try out all different tweaks using if possible the skyrim profiles
- every positive effect will be noted by it self
- all positive effects will be tried out together and adjusted to create the best effect.
- Not used: HD-DLC, Mods, ini-tweaks and on Ultra-Settings only.

Skyrim Graphic Profiles:
- try out, whether Low-, Medium-, High-Setting lets z-fighting vanish or become close to invisible; if not good enough ULTRA will be used to continue
- best profile will be used to continue

HD-DLC & Mods:
- will be implemented to look for any positive effects (using STEP 2.0.1.a and STEP 2.1 mods)
- focus on: LOD-, shadowing-, clouds-, fog-, light-, HD- and terrain-mods and other promising mods (suggestions are welcome)

INI-Tweaks:
- tweaks of which I know that they have/had a positive effect
- implementing tweaks as proposed by various forums
- analysing ini configs by DNA , Kieranh7, people who don't have any z-fighting or got rid of it.

Conclusion:
- summary of all my collected data posted in this forum for reference.


Comment: Everybody who has too much time to get rid of it can join me. Every help is thankfully accepted! :)

Hey, it's me again. Work is doing good so far. I'm going to post an update on the drivers asap. What I'ld like to know is if by any chance it might be possible to get every single Skyrim patch as a separate download. I couldn't find anything like that so far. I'ld like to check, whether z-fighting became a lot worse with new updates as I've figured out for myself and especially which update is responsible for that. Maybe that might help some other people who actually know something about programming to find what's causing some graphic cards trouble and others not. Anybody with some leads?

anyone running windows with full file protection going (the default) will have everything backed up automatically, I just reinstalled windows myself so I've got nothing.

Control Panel, System Security, System, System Protection, System Restore on Windows 8 its the same for win 7 with probably some minor variations in names I forget.



You'll get a listing of every program intall and update ever done on your computer. Just rollback one step at a time and backup each exe. By the way if you have up to 1.3 that's a fine place to start 1.2 was a complete catastrophe.

Thanks a lot!
I'll check it out.
Here's my recent update!

I've made a video comparison of the very same in game situation with 5 different nVidia drivers.
Here's the link:
I would like some feedback: which of the different drivers do YOU think is the best considering z-fighting?

You'll have to get maximum resolution first (bottom right corner). Otherwise you cannot see the difference.
I included lots of detail in the description. Thanks for your help! :)

So, I'm ready for the next step: - Driver 295.73 had the least z-fighting, but Driver 296.10 has similar results. I'll proceed with Driver 295.73 as of tomorrow with my tests. - In the end there isn't a whole lot of difference between the different drivers, so the choice of the driver should be considered wisely. I recommend choosing the driver which presents you with the most performance of all. - The next week will show, whether z-fighting can be reduced a lot or not. Given the time, I might make tweak-tests for the newer drivers, too.

Sounds good Torm :) Luck with the testing and I for one look forward to seeing your results. I'm still waiting for the next nVidia driver release but as I'm still on an old 8800 GT I don't expect to see that '20%' performance boost, lol.

Nice job. :) Figured I'd point out however that there is a newer beta-driver out (very recent), 301.25 (https://downloads.gu...nload-2901.html ). It had no changelog however so not sure if any of the Skyrim-issues are fixed, will look through the discussion-thread over on guru3d.

Edit: Only mentions of Skyrim in the thread was this:


Skyrim285.62 whql - 48.2 fps
295.73 whql - 69.9 fps
301.25 beta - 73.8 fps


Good performance in Skyrim and L.A. Noire and Dirt 3. Constant 60+ fps in Alan Wake


I played Skyrim, Crysis 2 and Battlefield 3 mainly. Crysis 2 and Skyrim are definitely smoother, BF3 looks kind of the same, still few stutters here and there but nothing too harsh. Also I gained +10% on 3dmark stuff.I think you should give them a try

Thanks for the input! I'll check the 301.32 Beta driver 64-bit out, and maybe then I'll go back to 301.25 (It says it's supposed to be for gtx 670 and 680, I got GTX 570 SLI). I'll post some feedback, but probably no videos (unless a miracle happens as I try them out and all of the z-fighting vanished)

Oh 301.32 came out during the night aswell? Great great :) And yes, 301.25 is for 670/680 but if you use the .inf file from .24 or so you can install it fine. I have 560 myself
