    Anyone had any luck getting Crossfire working with FalloutNV? I've tried forcing Crossfire via RadeonPro, but so far no dice.

    Does Fallout 3 work with CFX?

    If so then since it's the same engine you might be able to use RadeonPro. Create a custom CFX profile for Fallout 3 (using the Fallout3.exe game executable) then use it to force CFX in Fallout: New Vegas.

    Alternatively, if you can wait a bit longer then there may be a profile for this game with the 10.10 WHQL drivers and 10.10 Application Profiles that are supposed to be out today. Or maybe not knowing ATI...

    Using AFR and I've tried multiple crossfire profiles including AFR friendly D3D and Oblivion.

    Try what Darren Hodgson suggested, create a custom profile using Fallout3.exe

    I tried renaming it, too. No luck here either. Using the 10.10 beta drivers.

    This games performance is bull****, when i run it on Win Xp x64 i get 60+ frames almost anywhere.
    When i run it in the same place on Win7 x64 i get about 40-50 frames.

    Okay, looks like we have a fix. Download this d3d9.dll and put it in your falloutNV directory. After doing so I was able to get CFX using RadeonPro.

    How can developers release a game without testing it fully first ?

    Yeh that d3d9.dll works, had to rename the game exe to fallout3.exe to get full cf performance tho.

    If I leave it as FalloutNV.exe I get 30fps with Ultra high settings and 2xaa, 10fps less than without crossfire.

    If I rename the file to Fallout3.exe it jumps to 80fps, but it's not using any more than 76% of the GPU's, and im getting huge slowdowns when going into vats... :bang:

    Well its working with nice FPS for me, but its the most ridiculous game, you cant kill anything even with 100 shots of a rifle and a full few clips of the pistol

    Odd, I didn't have to rename the executable to get Crossfire fully operational. One reason might be that I'm using Radeonpro's ability to detect the falloutNV launcher and implement settings following launch. I have the 'Launcher' toggle set to 'custom' in RP.

    That's with the rig you have in your sig? Single 5870 overclocked to 980 /1300 gives me 60 - 99+ on 10.10 drivers. And that is with everything maxed out.
