    This is just a general G3D question: How much of the performance optimization are shared between drivers? Are half the FPS from how well G3D is optimized and the other half for the specific card driver?

    Nouveau drivers don't use any kind of buffer management that comes with Gallium, which helped us to get a lot of speed. For example pb_bufmgr_* managers are used only in r300g, r600g, and svga. u_upload_mgr is only used in those three plus i965. Maybe they have something in the kernel?

    I second the Radeon vs Nouveau proposal.

    Nouveau 3D is not there yet.

    I run Fedora 13 with latest updates and have been using nouveau. 2D is great. 3D sucks. I have to disable shadows and reflections to play neverball and neverput - both of which will hang the system on occasion. When the system hangs, it won't boot properly unless I unplug the power cord and wait for a while - seems vaguely like a thermal problem. I'm running an NV44A fanless card. When enabling desktop effects, the dialog boxes drag OK vertically or horizontally, but diagonal dragging results in painfully slow repainting. BZflag renders fullscreen garbage.

    So for me it's been a fine 2D driver for some time, but 3D is just not reliable.

    And BTW phoronix. When you say the latest is faster than the older version, please include the old version in the benchmarks for comparison. Also, if you're going to compare multiple cards, please pick one from an older generation, not two NV50 generation cards.

    Whoah! Last time I checked the Nouveau driver was comming in at about (literaly) 3fps at Quake3.

    Very nice improvements!

    I guess the nVidia guys don't have to be pissed at State Trackers now

    BTW this also proves, next to how hard the Nouveau guys work, how great of an investment Gallium3D is!

    You can expect to double the frame rate when Power Management gets released to the public.

    Nexuiz is now playable on my laptop (NVS140M) with a framerate between 30 and 49fps.
