My second 980Ti would be helpful in this game, worked fine in bf3. Bf4 and bf1 ---

So you can have SLI in DX11 with no Ray tracing or have Ray Tracing with DX12 and no SLI. ---

Is ray tracing compatible with multi gpu? BF1 added mGPU support around August 2017. DX12 was a stutter fest so it was hard to use it. ---

Uninstalling the new drivers with the built-in “Clean install” setting and installing 416.34 worked for me. Also had to turn on the future frame rendering thing as well. Getting ~95% on both cards. ---

Getting ~95% on both cards. it never worked for me in the beta with that driver. but i’m gonna try your fix. whats the point of buying a thousand plus dollars in video cards if Dice and Nvidia is just gonna screw us… ---

not even the 2080ti is going to hold 144fps at 1440p, let alone at 4k … Not on all ultra. we do this to have the best and they still crap on us. ---

I know it’s not a question about Sli but i have a small problem when i play grand operations on Twisted Steel i don’t see the rain , all my squad it’s having rain in that map and i don’t have it . And about sli i can’t get it work 80-90% from the video cards. I’m using an i9 procesor and 2x 1080ti and all i get it’s 50-60% from the video cards. Thanks. ---

With the bf1 profile i get around 70% usage on both cards. they never reach 90% or high 80s. The bf1 profile gives 97% sli scaling. Sounds like a cpu or pcie bottleneck on your part.

List your hardware, aswell as all ingame settings. 2 evga 1080s ftw hybrid 7700k at 5.0ghz under 70c temp. 16gb ram running the game at 3440x1440p a mix of high and ultra and AA lowest. Can play at 100fps with sometimes dips in the mid 80s. Changing settings all low or all ultra doesnt really give much improvment. The fps will still dip under 100 no matter the settings.

Hmm, there’s a known issue with SLI and G-Sync. Maybe someone else has an idea. I’m \*\*\* fed up with SLI so yesterday I bought a 2080Ti FTW3 Ultra. I’m going to sell both of my Titan Xp. So long headaches. Now I can actually enjoy gaming.
