I've installed F-12 beta on my new laptop with ati radeon hd 4570 graphic card, I was going to file new bug. With kms enabled, everything is really sloooow, with 'nomodeset' it's much faster. I can't say exactly "how" slow it is, is there anything I can use for measuring?
cairo-perf-trace is, afaik, the best we have: http://cworth.org/intel/performance_measurement/
I'm not sure if bug reports on this are useful. 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?
I think we already have bug open for slowness with KMS, r600/r700 is missing few pieces. We will work on performance latter, likely not in time for F12. We are mostly focusing on fixing bugs which makes GPU unusable first.
Thanks, Jerome. So, Michal H, there's no need to file a bug for this. Thanks for reporting it, though.
