Skyrim Crossfire Fix that Actually Works (lolol!)

[thebunnyrules]

Having crammed packed Skyrim full of mods to point of it's virtual seems being ready to burst, I was relying on my second AMD R9 290 to give it some FPS punch. You could immagine my horror when I found that running it in Crossfire created tons of artifact issues, stuttering and had pretty much the same FPS as running a single card. It seems from what I read on some old post that AMD messed up the Skyrim crossfire profile back in 2012 and never bothered to fix it.

Well, I bashed my head on this issue for a whole week and scavenged the forums for a solution. I found alot of posts. Some recommended to rename TESV.exe to Oblivion.exe to enable the Oblvion crossfire profile. Another recommended using an Assassin's Creed profile. Nothing was really working well. Oblivion profile killed my enb's depth of field and was causing tons of CTDs. Using the AC:Bro profile killed the FPS making CF pointless.

In the end I found my own solution:
------------------------------------------

In AMD Radeon Settings, choose Optimize 1x1 under Skyrim's Crossfire Profile. Next, turn off Surface Format Optimization. Turning off SFO made all the stuttering, low FPS and lag go away. The Optimize 1x1 profile doesn't have any flickering.



It's not perfect but it's well worth it:

--------------------------------------

After having used this profile for about a week, I noticed a couple issues:
- the first 5-10 minutes after starting the game, the FPS is lower but after that initial period, the game has pretty solid and constant FPS. It might be unrelated to CF. It could just be my scripts getting loaded at the start of the game...
- There is still the occasional flickering that takes place on as light get reflected off of water. I'm not sure if it's ENB related. It was a rare occurrence when I was on Realvision and much more frequent on K Enb Pure Light.
- I had some issue with ghosting but it turned out to be my ENB. I had turned on temporal AA which is incompatible with multiGPU setups.

Personally, I'm more than happy to live with the few quirks I'm getting from running this Crossfire with this profile as the performance boost is almost double what I was getting with one card.

I am using Crossfired 7970's and this/crossfire does not help performance on my system.
I get better performance with single card than 1x1 optimized.
The game is very mult-threaded now and I max out a single GPU on a FX8350.
In the old game i didnt max out the GPU due to poor single threaded performance.
It would be nice if they created a profile for this game.

I am talking about Skyrim Special Edition.
