[tecuma]

hello community,

i try to run world of warcraft within the environment mentioned above. i am using a 64bit environment with multilib with 3.0.6 kernel.

when i start 
wine Wow.exe -OpenGL
i receive the following message at the end

a message box come up which tell me that wow could not start 3d acceleration.

i use the open-source driver as described in the gentoo documentation.
when i check the 3d capabilities all seems to be fine.

celsius ~ # glxinfo | grep rendering
direct rendering: Yes

glxgears is working and showing about 1400.000 fps.

eselect opengl list shows the open source driver
Available OpenGL implementations:
[1] xorg-x11 *

did i miss something to configure for wine?
did i made a mistake or forgot something in the setup for my gpu?

regards
