Do you have any idea why I see those delays when playing a HD-movie? They do not appear when switching to dynpm. I use the latest llvm(3.4svn), libdrm(2.4.45), mesa(9.2.0 devel), xserver(1.14.99.0), xf86-video-ati(deve) - all fetched from git as of 2013-06-26. -- --joshua _______________________________________________ dri-devel mailing list dri-devel@xxxxxxxxxxxxxxxxxxxxx http://lists.freedesktop.org/mailman/listinfo/dri-devel
