When I try to start wow from wine in opengl mode even the opening menu has REALLY low FPS (1-2).

System specs:

ATI Radeon Mobility 1100
AMDTurion x2 1.6 proc
1.5 gigs ram (128 go to the graphics card)

The game loads up so much smoother with d3d than opengl which everyone says should not be the case.

Any thoughts?
