Help with wine/graphics...

I installed latest 64bit FreeBSD, I installed 32bit version of wine because executables of game are 32bit.. every time i want to run different games this gives me pain:
libGL error: No matching fbConfigs or visuals found
libGL error: failed to load driver: swrast

GPU: Nvidia 8600 GT with nvidia-driver-340 installed (with linux support)... what can I do?

Thanks in advance, cheers! :D

EDIT: Btw, when I delete /etc/X11/xorg.conf and run startx... screen have glitches but I can actually run game... without error, it seems that this xorg.conf makes some problems.. I run X -configure && mv ~/ /etc/X11/xorg.conf... I don't know what I did wrong.
Generating an xorg.conf is not recommended and has not been recommended for quite a while. Yours is causing you trouble, so why are you still doing that?
