It runs perfectly on triple screen but the performance hit is insane. even on low my 7970 can't get a stable 40 fps...
For me I had to disable SSAO in the config file (C:\Users\Name\Documents\my games\Far Cry 3\GamerProfile.xml) to get a stable fps, and it looks nicer now to because I can run all other settings a lot higher now.
I'm actually finding it incredibly hard to get consistent FPS on multi or single monitor play. I believe there are some flaws in the engine that need more optimization. I can get around 40+ fps multi, but throughout play it drops to 15 or so for no apparently reason. I might try disabling the SSAO like you have to see if that is the cause. When I dropped down to single monitor (everything max) it wasn't too bad, 60-70 fps and this is really what the game needs to play out to be smooth. 40 still doesn't cut it, or it might if it didn't dip all the time.
I'm running 2x3gb580's, but I was reading in a Ubisoft thread that the game is very CPU heavy? I'm not sure.
