I have one game (Polda 5 Czech version only) which is unplayable without
vertex blending, with latest wine and my nvidia card it looks better,
but it is still not perfect (I have registry key for software
emulation), If you want, I can send you some debuging output, or
screenshot. So SDK demos are realy useful to get wine work with more apps.
