I'm having issues with Far Cry 3 and my crossfire 7870's. I'm using a 120hz monitor at 1080p. I'm running the game on Ultra and according to FRAPS my frame rate is anywhere from 58-80. But the gameplay is choppy and laggy as hell. There's nothing smooth about it. I know tom's tested Far Cry 3 with 7870's in crossfire and they didn't mention any problems with the game. Is there settings I can adjust to solve this problem? I don't know what half of the video settings mean. I'm using 11.1 drivers and haven't had an issue in BF3 since adding another 7870. Any thoughts?

Figured it out for now. Running the game in DX9 stops the choppyness.
I seemed to have the same problem. Running at 60+ FPS but game seemed very choppy. Why include an option that they clearly haven't optimized yet... Ubisoft sure loves their PC customers....
