    I just upgraded my computer with another R9 270 because it wasn't quite cutting it in Fallout. Tested it with Unigine Valley before and after adding the second card and got about 80% higher score. Play fallout and there's no noticeable improvement, but there are periods of horrible chunky lag like 3-4fps. Most of the info I've found is before the FA4 1.3 update in February and apparently not very useful. All driver's up to date and the game is up to date via Steam.

    So, does anyone have Crossfire working with Fallout4?

    Nope.
    It's not always graphics card(s) issues with newest games. How much ram you running it with.
    super_Chris says thanks for this.

    Could it be an incompatibility between the 2 different cards in crossfire?
    what's the default renderer for the game? I know some games are only optimized for DX10.
    I had horrible framerates, hell, it was unplayable, in Planet Explorers back when it was on the Unity3 engine.
    The 32 bit engine would not utilize more than 2.8 gigs of ram but the game required a shit ton more. I had to play in (steam) offline mode and shut down
    all programs that run in the background. The amount of ram you have doesn't sound like the problem. I was only at 4 gigs but upgraded my mobo and ram to 32 gigs
    when PE rewrote for the Unity5 64 bit engine.
    Does anything get better with lower graphics settings?

    There's a Crossfire profile for Fallout4 but it still seems to run like shit. I'm still screwing around with random settings trying to get it working. With this setup it should be at Ultra everything and playable, but it isn't.

    I'm going to try the Skyrim profile next.

    EDIT: I have radeon settings open on my second monitor and it's showing my second GPU at 0% activity while playing only going above 0 for a second or two at a time. Is this just a game works issue?

    Try the hack? If so, back-up first.

    That's what I run games on and max settings are standard now. ME Andromeda will be awesome this winter.....if it releases as planned.

    My Radeon 7950 3gb was a steal when I got it a couple years ago but it's beginning to show it's teeth. I don't play any new games unless you count UT4.
