I'm with ya!!!!! Bethesda's Customer support involves questions they generated, and answered, as an end-all-be-all solution to customers questions. They seem to have converted to auto-responding to customer questions and no longer communicate directly with customers.

HEY BETHESDA , I WAS RESPECTFUL WITH MY QUESTIONS, AND YOU SPIT IN MY DIGITAL FACE!!!! GET OFF YOUR HIGH HORSE!!!!

You either force SLI on or off in the driver settings. That simply means that the GPU's will each render a frame in an alternating fashion. However, what it doesn't necessarily mean is that you're going to get a performance increase out of the deal. If the next render must wait for the previous render to finish, then you're spending processing overhead managing the SLI, but not getting any benefit. The more work a GPU can do independently when rendering a scene, the better SLI scaling you'll see. When it comes to the profile, that's exactly right -- it's just a "best settings" that automatically change the settings within the SLI system itself depending on what application you're running.

It's not as common as I'd like it to be that games support SLI at launch. Outside of the Unreal Engine, SLI is generally supported, so smaller studios using someone else's engine typically come with good SLI support out of the box; however, in-house engines are another matter, and it's really hit or miss as to which support SLI and which don't. It's interesting, though, because I've run SLI since 3DFX came out with the tech in the late 90's. Back in those days, SLI was able to be ubiquitously used, from what I recall at least. Of course, the graphical fidelity of games in those days were much simpler, so that could be the difference.

Ok cool so at least with have a workaround with Nvidia inspector for now until Bethesda release an SLI patch. I'm sure they will. They supported Skyrim well, even making it LAA.

Watch, Bethesda will come out with a response like Rocksteady just did regarding Arkham Knight. SLI is "not practical".

This "fix" and all the others floating around don't work.

I run the game at a very high resolution: 5760x1200. So I need a lot of GPU power to get good frame rate at that resolution. This "fix" and all the others posted on the internet only gives me 20-30 FPS. I know FOR A FACT that my system is capable of much better frame rate, and I know for a FACT that these SLi "profiles" are not properly utilizing my GPU's!

It's on both Bethesda and nVidia. Am I just yelling at the wind, or is Bethesda actually going to respond? Hello!?

Bethesda will not respond here.

This is a user forum.

Yet the point remains. Bethesda, you need to make SLI work.

I'm wondering if anyone on bethesdas end or nvidias end is actually working on this or if this is going to be another witcher 3.

??? TW3 has a proper Nvidia SLI profile and works just fine for me.

No it doesn't actually. I've been back and forth with nVidia's Customer Care, and they have escalated a top prioitiy bug where if you run nVidia Surround + SLI, there is absolutely zero SLI scaling and performance. They are able to replicate the problem, so this isn't true. Now, if I ran every game on one monitor, then I'd never need to worry about Framerate issues. But I prefer nVidia Surround on ALL my games due to how much infinitely better it is then single monitor gaming.

At any rate, a good samiritan named Helifax on the nVidia forums found a VERY temporary work around:

- SLI compat bit (DX1x): "0x280000F5 (Lord of the Rings Online: Shadow of Angmar, Lost Planet 2, Pollen Demo)"
- GPU count: 4
- SLI Mode on DirectX 10: AFR (NOT AFR2)

This is by far the best "work around" I've seen, since I actually get more than 20-30 FPS. However, the FPS in Fallout 4 is so f*%!ed up, that I actually get better FPS out-doors than in-doors -- makes no sense, that's how bad it is.

Bethesda REALLY needs to patch this game. And nVidia REALLY needs to make a proper SLI profile.

EDIT:

ISSUE SOLVED!

I removed the Fallout4Prefs.ini and "Fallout4.ini out of the My Documents/My Games/Fallout 4" folder. I was originally removing them from the "Steam/SteamApps/Common/Fallout 4" folder.

Didn't release there were these two directors holding the same files. This may actually help out a lot of people! Make sure to make the changes to your INI files in your My Games/Fallout 4 folder and not your Steam folder. The Steam folder one seems to make no difference.

I think the key there is that SLI works like Zanderat says, but specifically not with Nvidia Surround.

I think you are right. I am not using Nvidia Surround.

Shameless bump.

I don't understand at all what the problem is, Oblivion had sli support, fao3, fo nv, skyrim, ESO has it, Bethesda needs to step up their game, this is a common sense out of the box type thing. I would be pretty cheezed if I bought one of the best gpus on the market , that happens to be a dual chip gpu, and only half of it works.

I realize it's Turkey Day, but could Bethesda at least acknowledge the problem!?
