Wow awesome. Thanks @noonemusteverknow!

After thinking everything was fixed, I ran into another problem with top of the Anvil Lighthouse... Basically giant squares are floating around it. It seems to be AO and Detailed Shadows.

Also another problem is grainy clouds, which again seem to be caused by ENB...

Is there any fix for any of this?

You can solve this problem by replacing the "problematic" cloudy sky texture by another sky texture. You probably use "Atmospheres Heaven", so you normally have several cloudy sky textures in your sky folder, just replace this one by one of the other which normally works correctly.

Right now I'm happy with performance and memory handling...

However I ran into this landscape texture confict (?) you can see here: http://imgur.com/a/loHSs

It looks like CarlosS4444 had the same issue? http://www.gamesas.com/topic/1524522-can-a-retexture-cause-a-line-on-the-ground

I tried uninstalling QTP3 but that didn't solve problem.

I couldn't find a fix for the landscape seam issue caused by Lougain's Landscape Retexture

After turning off everything but Lougain's mod, it seems the problem was his all along

Going back to good ol' QTP3

have you tried not mixing QTP3 with Loiugian, but only using one or the other?

Yes. The only fix was not using Lougain at all :\

And that is not cool, because Lougian textures are very fine. Same situation here.

have you tried asking Lougian?

Well, I recall I posted a comment about it, but I don't exactly remember, whether he decided to do something about it or not.

You or anyone else also might give him a comment about it, might encourage him, who knows. Just find my posts and reply there.

which SweetFX-Version do you use? Oblivion Reloaded does not work with SweetFX by me, the water isn't correct.

I use SweetFX v2.0, it works fine with Oblivion Reloaded water for me.

Strange, I downloaded "ReShade 1.1.0 with SweetFX 2.0" and with OR the water isn't transparent at the border and underwater I can't see through the water.

Any news on the project?

I didn't see any real project here, the OP author only wanted help with his load order AFAIK. But I agree that the topic name suggest that there is some project of making Oblivion Mod Guide going on...

I've written a little of the guide but unfortunately dealing with some life issues.

Planning on revisiting in a week or two once things calm down. Thanks!

Good to hear about the guide, and good luck with issues!
