Game is running great for me on my laptop @1080p. i7Q, 16GB Ram, and a GTX460M (1.5GB). Textures are at Ultra, everything else at Medium, with 2xMSAA and HBAO on.
Think I may try turning HBAO off and setting either terrain or effects to High.
Still don't know why Battlelog doesn't show me Ping for servers.
