Not sure though what you mean by pretty slick, in my experience it is usually useless due to glacial performance (though I guess maybe it's better thanks to UMA compared to old radeons). -- You are receiving this mail because: You are the assignee for the bug. --1369341197.Cb873.4276 Date: Thu, 23 May 2013 20:33:17 +0000 MIME-Version: 1.0 Content-Type: text/html; charset="UTF-8"
