is anyone else experiencing persistent flickering with Crossfirex enabled? I have dual HD 5500's but if I enable crossfire I get a vertical row of tiny flickering squares towards the right side of my screen, and the game will randomly freeze and lockup, requiring restart.

I have the most updated drivers and profiles available as of this morning.

Anyone having similar experiences and/or a solution? The game is "playable" with one of my cards at 30 - 40 FPS, but I'd really like to take advantage of my second card
