I saw a bit of flickering in one of the new DLC maps. Nowhere else though.
I'm more concerned with the player tags not showing on friendlies bug being fixed
BTW three of the maps in China Rising are very cool, and 2 of them are fucking awesome. One of them (Guilin peaks) is the best map I've played in a first person shooter in a long time.
I'm very happy with the DLC.
