To some extent, slow performance with KMS on some chips is a known issue. Jerome, do you want bug reports from people who have this problem, or would more reports not provide any new information? > btw, mesa-dri-drivers-experimental does not work at all for me (glx apps > segfault) Your card's r700, not r600, so that's kind of expected; the current code isn't expected to work well on r700 (possibly not at all, I'm not 100% clear). r700 and r800 support should follow r600 relatively quickly, though. -- Adam Williamson Fedora QA Community Monkey IRC: adamw | Fedora Talk: adamwill AT fedoraproject DOT org http://www.happyassassin.net -- fedora-devel-list mailing list fedora-devel-list@xxxxxxxxxx https://www.redhat.com/mailman/listinfo/fedora-devel-list
