   D3DDEVTYPE_REF
  Hi,i've got 2 triangles, the second one as x-coords of his vertices bigger than the first ones of 20px, so it's on the right of it.How can see them correctly if i use D3DDEVTYPE_REF, while if i switch to D3DDEVTYPE_HAL i see the second one in wrong position, with a vertex very near to (0,0) point, while it's not there !!!Does REF/HAL setup influence vertex representation ??? In which way ?Bye   
  The REFerence device is an accurate implementation of the pipeline. HAL isn't. Make sure you set all the states you need before rendering, because drivers might not set them to their defaults correctly.   ;Quote:Original post by CoderThe REFerence device is an accurate implementation of the pipeline.
