Tried both drivers - same performance on both.

Cards only at 40% usage and cant get over 60FPS

2x1080ti with 5960x @4.4Ghz

Please help if anybody can advise

Turn on future frame rendering in the game

You got vsync enabled by any chance? All the presets enable it by default, you have to use the custom setting to disable it, it'd certainly explain low gpu usage and inability to go over 60fps.

Tried disabling vsync - no change in FPS

Forgot to mention I have a 3440x1440 100Hz screen.

Also tried changing future frames on and off, no frame changes either

To all of those looking to make SLI work on BF:V, It looks like I've got it working.
3440x1440 with 2x 970gtx's and a few tweaks, both GPU's running on 90-100% and the result is 70-100 fps with (except TAA) everything on Ultra! What I did to make it work?
1. Nvidia Driver version: 416.81
2. I actually downloaded a profile from the following link while googling for the solution: and if I remember correctly I had to reassign bfV.exe and the bfVtrial.exe to this profile. Although I haven't compared this custom profile with the BF1 one; I assume it's the BF:V profile with the SLI properties of the BF:1 file overlapping it.
3. Future Frame Rendering has to be turned ON. This basically turned GPU usage on both to 90-100%
4. TAA Low; because most TAA won't work very well with SLI in the way it works. That gave me the fps boost of 50-60 to a minimum of 70-80.

I also turned Vsync of simply because of a G-sync panel.

Hope this combination works for you lads too!

NO Luck

I really dont seem to have luck with SLI lately

Minds haring a screenshot of both settings menus so I could clone them and test from there please?

Freezoide · November 11, 2018 7:05AM

You should be able to clone both BF1 + Inspector when being accurate with the following:

https://i.imgur.com/hGKj2mU.jpg

The GPU-z's both indicating different voltages/GPU Load shows they're firing up in the menu already.
Hopefully it works for you!

P.S. I do remember that Future Frame rendering took effect a couple of seconds after exiting the menu going back ingame, other than that I really don't know why else it works for me.
P.P.S. Turning all on High and TAA High works fine too for fps. Thus TAA isn't that much involved in SLI performance apparantly

reverb_za · November 11, 2018 12:56PM

@Freezoide still no luck. Cannot get passed 60fps

Hmm, very strange indeed, have you tried switching between fullscreen and borderless modes, and also double checking your nvidia control panel settings to make sure sli is actually enabled and also that you're not forcing vsync via the ctrl panel.

Just to reiterate,

- If you're using driver 416.81, you'll need to use nvinspector to change the sli compatibility bits to either the bf1 profile or star wars battlefront 2. Also, in the Nvidia ctrl panel, the game will show it's running in single gpu mode, that's fine, the fact you changed the bits will override that anyway.

- If you're using driver 416.34, sli should work by default, without needing to mess with nvinspector. Just make sure you're running in dx11 and that the Nvidia ctrl panel profile for the game says it's running in "nvidia default: sli" and not "single gpu".

Beyond that, I'm out of ideas...

Turning taa to high or low doesn't make a difference to fps because the temporal filter is being applied regardless, and that is what is giving issues with sli.

TAA has a 10 to 20% performance hit over FXAA when using sli, but Dice in their infinite wisdom has forced TAA on, giving no option to disable it...

Hello, thanks for your help armoredmarmite ,now it's working the sli ,i did uninstall the nvidia driver with DDU and then reinstall it back and it's working.

But now i see the video cards are working only 50 -60 % not 80 or 90 % and i get only 80-100 fps this is verry strange,from what know i need to have at least 100-130 fps.

reverb_za you need to set the Future Frame Randeding to On and the GPU restirction memory to OFF and Vsync to Off ,tray that and see if you can get more fps,butwith that rig you need to have at least 80-100 fps in 4k .

REPERCUSSIONS · November 12, 2018 12:13PM

You shouldn't have to alter config files for sli to work... hopefully nvidia addresses this issue.

reverb_za · November 14, 2018 6:52AM

So back to previous drivers - haven't updated either of the new updates after a full clean install from DDU and we back to normal FPS again. Anybody tried latest latest drivers?

CartierOne · November 14, 2018 5:55PM

Hello,anyone tried the last driver on sli ?

FrontFighterHD · November 15, 2018 11:20AM

Hello!

I also had some struggles with the SLI - I'm running BF5 on Ultra @ 3440x1440 with an 75hz Monitor.

I'm using the 416.34 Driver and SLI didn't seem to work (2. Cards was idling)

#1 Fix was activating "Futur Frame Rendering"

So now both Cards had about 30-40% Load.

#2 I downloaded the Battlefield 5 SLI-Profile, which Freezoide had posted () and assigned bfv.exe to it.

Now im having 50 to 60% Load, and some more fps, nut i think the CPU is now the limiter, cause its at 95% Load. (i7 4770k)

possiblyapanda · November 15, 2018 12:32PM

I think more importantly is where is DX12 multi gpu support? Dice hasn't had a multi gpu implementation for DX12 in any of it's titles. Can frosbite even support it? Is ray tracing compatible with multi gpu?

Nzz1 · November 15, 2018 4:43PM

We need DX 12 sli profile, so we can play with RTX = ON

Running 2x 2080ti Nvlink.

This could be very correct because even my 8700k @5.3ghz all cores is running 60% all the time. That's 12 threads 5.3ghz, basically insane.

Can i ask what cooling hardware youre using? And what are temps while gaming..?

Sry for off topic

You can, make user.cfg in game directory add WorldRender.LightTileCsPathEnable 0 command, and in game put motion blur to 1%
