Enabling crossfire on my dual radeon 5770s actually DROPS my fps. Is their anyway to fix this? I disable crossfire and get 40-60 fps, but it just pisses me off that I can't use my hardware :shakehead:

Just disable it, and be happy you get a good FPS. A lot of us are stuck with an unplayable game.

Yeah, Crossfire systems tend to have problems like that. There'll probably be a new driver that'll fix the problem.

Check with MSI afterburner or the crossfire logo thing. I just wonders how peoples are using crossfire for this game when no crossfire profile exist for this game.

Enabling/disabling and using crossfire are 2 different things. I can enable and disable it, but it doesn't mean it's working for FNV (Lack of profile as you mention.) just that the cards are set to use crossfire if a game does have a profile.

OP:

I tried both disabled and enable and it was the same FPS in both.
