Hello,
Yes, without displaying the mouse and it's very slow (as if you were playing a game with direct rendering to No). But with dri, i have 1200fps and with ati 1900fps for common glxgears, there is a significative difference.
glxgears isn't a benchmark... If you set Option "AGPMode" "4" Option "EnablePageFlip" "1" Option "BackingStore" "1" in your device section of the dri driver, then the performance should be equal to fglrx(~2000 fps). If you install driconf and enable HyperZ, then you should get another boost. Alternatively, you can create a file /etc/drirc with the following content: <driconf> <device screen="0" driver="r200"> <application name="all"> <option name="arb_vertex_program" value="true" /> <option name="texture_level_hack" value="true" /> <option name="hyperz" value="true" /> </application> </device> </driconf>
The first option enables software emulated vertex shaders, but I don't know if they work. The secound option enables a hack which increases the maximum texture size by a factor of 4 (1024x1024 -> 2048x2048) if you have the dxtn decompression libary installed. google for libtxc_dxtn050908.tar.gz, it should be the first entry. Installing this library enables compressed textures too, which can improve the performance drastically in some games which support it. The "hyperz" option enables hyperz, which also increases the performance, especially in glxgears. With all the options enabled, I get about 3670 fps in glxgears(Acer travelmate 803, 1.6 Ghz pentium M, radeon mobility 9000, Xorg 7.0 with the dri driver). But again, glxgears isn't a benchmark. My experience is that the open source driver offers equal performance since Xorg 7.0, quite often it's faster, but only in unreal tournament 2004 it's significantly slower(general > 40fps, but sometimes only 15-20 fps, which makes ut unplayable. Surprisingly, this doesn't depend on the settings, so I think it's a driver bug)
So, i have just reported them the problem and explain that it works with dri, so i hope they will make something to correct it....
Don't expect too much from at :( Just have a look at the linux driver forum at www.rage3d.com
