I'm not a great fan of DoF as most often the effect is made too strong to be 'naturalistic', but that's just personal taste - more to the point is the performance hit.

An example can be seen in Enb preset - Vanilla Look For Independent Bokeh DOF Only by MarMScA which attempts to allow the use of a Bokeh type DoF without the other ENB effects. If you check the screenshots and note the FPS counter the hit is quite significant.

@torminater I've started a thread in the ini tweaks section and intend adding your findings and solutions into the first post in that thread - if you would like to write a clear summary of your work and PM it to me I'll edit and include it in there :) If not you'll have to trust that I can understand what you have done and achieved, you get the credit either way, lol. Do you mind if I use your vid link as well as it is both a good visual explanation of what z-fighting IS and a proof of the value of your work?

RL comes first torm :) Best of luck with the Uni stuff and we'll see you when you're done (TheCompiler had the same problem and this was one of the delays to the latest version, so you're in good company).

Well, holy s*** that's a FPS-drop xD 20 FPS? hmm. well. I dropped by at least 25 FPS in extreme game situations by applying ugrids 9 and my own little tweaks if I'm in wide open spaces. So another 20 FPS would set me down to 25-30 FPS. And that's with a clean vanilla-install at Ultra-Settings. No. F-ing. Way. I'll have to check out variations of that set-up. And I need STEP 2.1 to actually look into the performance part. It would be weird if STEP suggests tweaks that make a normal STEP-config unplayable, now wouldn't it? ;-)

I haven't tried it, but I would suspect that using Dynavision for DOF along with RL wouldn't give near as much a performance hit. You can also adjust the amount of DOF that gets applied with Dynavision. Would be curious to hear if anyone has tried that particular setup.

Well atm I only got my little laptop to work with. Since I did all the testing so far on my other computer that testing will have to wait until at least tuesday. I'll look at the whiterun walls flicker issue closer once I got some more time. ugrids is rather drastical. There might be a performance version of that somewhere out in the ini-universes. If I find anything like that, I'll info you guys as soon as I get stable results.

DOF is certainly not for everyone due to the performance hit (like some forms of SSAO), but I like a subtle DOF effect.

Note also that Xfire/SLI significantly mitigate all FPS hits, so folks with those kinds of setups are best suited to applying such enhancements. I would guess that all FPS hits will be cut in nearly half with 2x Xfire/SLI.

So I finished the draft of my z-fighting guide and sent it to Bealdwine for further inspection. If somebody else wants to see it, too, just send me a message!

As added information concerning DOF, I tried Dynavision (without any lighting mods), and adjusted for slightly weaker DOF effect. The good news is that I did not experience any FPS loss whatsoever. But for me, it didn't hide the z-fighting in the distant mountains. Forgot to check wall-ends, so will probably do that soon.

Hmm... what about if you increase the DOF or use this mod?
atm i'm not able to check it myself (working in a lab) but I'll try it out just for the heck of it.

I'll try increasing the DOF tonight and see what happens. I hadn't come across that mod with only Bokeh DOF, but will give that a try as well. Was hoping the lighter application would help as I'm with zMan, I don't like it too strong.

OK, so yesterday I had a very brief look at my laptop considering z-fighting. It is quite strong there, too, but my problem over there is, that I can't run Skyrim on Ultra smoothly. I have between 19 and 27 FPS. That doesn't really give me the option to expand the distant LOD by a whole lot. I'll try some other things, but first of all I need to get above 40 FPS... without skyboost probably in vain... What also disturbs me by a whole lot, is that all the draw distance settings I found could not help about this one problem. Go to Azura's shrine and look north. If you move fast from the left to the right you see the water near the horizon separating into blocks that have different colors. Neither WATER High/Med Res nor standard HD-Pack solved the issue. Maybe it's just my laptop. I'll have to do some more testing (maybe the HD-DLC has to be fixed even more?) and try to recreate the same phenomen on my other computer. Update is probably gonna be in 12 hours or sth like that!

Checked it through. It's a really nice piece of work torm :) so in the end I decided to just use it 'as is' LINK

@s4n - If you want to check it out as well you may have some suggestions for changes or additions.

@zMan - I've not had a great deal to do with the wiki as such, but torm's work may well deserve a place there? I can send you the original post for you to place it if you agree.

Feel free to do it yourself Bealdwine, the wiki editing guide is linked in the citizenship guide and do a search for highslide in the wiki to see some examples of how to use graphics.
