There is no issue with opengl in Wine. We directly wrap to native opengl. The issue is the poor 3d performance of the intel drivers. You could try to upgrade to the latest drivers to see if that helps a bit. The drivers are the whole problem. Only on Nvidia the drivers offer similar performance as on Windows, Ati performance is becoming better too but Intel isn't that great (their Windows and Linux drivers are completely different and don't share any code).
