[Wine] Assassins Creed White window

[Lude]

Hello,
at first, i'm sorry for my bad english.

since 2 days i will play Assassins Creed but if i start the game the window goes white after video.

I use wine 1.4-rc5 on Ubuntu 11.10
if someone need, my machine have a intel core i3-330M processor
with 4 GB Ram and a ATI Radeon HD5650 1GB

yesterday i used PlayonLinux with wine 1.3.5 but the same problem.
i made a regedit entry Direct3D --> "opengl" and OpenGl ---> VideoMemorySize "1024".

thank's for help
