And to get this fully on-topic, is there a specific reason why the dri driver is quite a bit slower (up to 50% in some subtests) in SpecViewPerf compared to the cvs version of july?
I wonder if it could be related to recent 2D driver changes, in particular the new bandwidth management code; that was only committed a couple of days ago though.
No, this can't be possible, the bandwidth management code was commited on the 12th or 13th October to dri cvs (unless parts of it were submitted earlier?) but the cvs version used for this article was from the 8th October. For the record, a cvs version from yesterday seems to be just as fast as that from 8th October (in specviewperf light-06), so the bandwidth code doesn't seem to affect performance too much. The performance drop happens really only in the subtests which deal with wireframes.
