wine users - Aug 2011 - 64 bit graphic card driver and source based games

Hi!

I just installed Natty 64bit and I am using Nvidia drivers(64 bit).
Portal does work but TF2 crashes when I try to start/join a game (basicly it
crashes when it should become 3D).

May this be related to the driver?
How can I figure this out.

Thanks a lot!
