Hi , I have an Intel board on my laptop 4500MHD , if I enable Vertex shader support and try to fire up anything the system freeze ( I have to hard reboot) withouth vertex shader everything seems to work ... this an output of this freeze : Code: fixme:d3d_caps:IWineD3DImpl_FillGLCaps Received unrecognized GL_VENDOR Tungsten Graphics, Inc.
