In my case, EXA or XAA had more or less exactly the same dragging performance on 3D. My card: 00:01.0 PCI bridge: ATI Technologies Inc PCI Bridge [IGP 340M] (prog-if 00 [Normal decode]) Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr- Stepping- SERR- FastB2B- Status: Cap- 66MHz+ UDF- FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort- >SERR- <PERR- Latency: 99 Bus: primary=00, secondary=01, subordinate=01, sec-latency=68 I/O behind bridge: 00009000-00009fff Memory behind bridge: d4300000-d43fffff Prefetchable memory behind bridge: dc000000-dfffffff Secondary status: 66MHz+ FastB2B- ParErr- DEVSEL=medium >TAbort- <TAbort- <MAbort+ <SERR- <PERR- BridgeCtl: Parity- SERR- NoISA+ VGA+ MAbort- >Reset- FastB2B-
It should be noted that this card was very well supported up untill the Xorg upgrade. -- Sluggish rendering since xorg 7.2 update https://launchpad.net/bugs/88815 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
