I was interested to see what performance I could get running Minecraft on my IBM T43 (ATI X300 graphics) using Gallium3D rather than the older mesa driver that comes with Debian Squeeze. With Debian Lenny I'd been using the proprietary fglrx driver which had superior 3D acceleration. With Debian Squeeze, which has the open-source radeon driver, with the ATI driver no longer supporting the old graphics card in this machine, fps dropped from usually above 30 fps to under 10 fps.
As a quick way of trying this out, I installed Ubuntu 12.04 LTS on a spare hard drive. However, I still get abysmal fps, so I'm not sure the driver has been set up correctly.
However, 'glxinfo | grep rand' returns:
direct rendering: Yes
OpenGL renderer string: Gallium 0.4 on ATI RV370
so I guess I am running Gallium3D after all. I'll be doing some more investigations, but perhaps someone has some thoughts on this off the top of their head. I don't know if Gallium 0.4 is a relatively recent version, how well the X300 / RV370 card is supported under Gallium etc etc.
