    Assetto Corsa does not support crossfire, and is overall better optimized for Nvidia graphics cards

    This may be true. I haven't seen anything official staying it. There may be a way to get it to work though. I remember something about re banning the .exe to something to the effect of AF-FRIENDLY our something like that.

    Short side note, but what happens if you have only 1 card active? Because I seem to have way more FPS with a 280X

    Sometimes that works but often it can cause flickering or a strobing like effect.

    Just for the Hell of it, in the AC graphics menu, what are your shadows set to? There's a well known bug with the shadows using Nvidia SLI, if they aren't set to high, then two cards in SLI drop the framerate to 25-30fps, but as soon as you set shadows to high, both cards work perfectly. I'm just curious if the same bug exists for AMD Crossfire or if the Crossfire profile doesn't work at all.

    Are you using the latest 14.4 drivers and have Crossfire enabled and reboot after you enabled it?

    Where is our Titan guy for his opinion?

    OT: The game is not done, and optimizations for crossfire/sli and video settings overall are usually done in the last builds before a final release.

    Pedro? :D

    Three video cards never scale as well as two. I am using two GTX 780's in SLI and they work just fine in AC other than the shadow bug. If I use the high setting it works fine, but if I use medium, it cripples my framerates.
