Try this patch, although it might cause other graphic issues it will allow you to use DX9 (I haven't tested it myself) : http://bugs.winehq.org/attachment.cgi?id=21072 - the patch http://bugs.winehq.org/show_bug.cgi?id=12453 - the bug report You can also try this patch, that worked with wine-1.1.15 (and a few releases after).Worked great with Portal and HL2:ep1/2. Doesn't work with newer wine releases, however.
