I don't like using beta drivers, but some times that is the only recourse. You might contact the maker and tell them the beta driver worked to find out when the release version of the driver will come out.
BTW, where did you get the driver, from the GPU maker or the card maker? I ask because I prefer getting drivers from the card maker, and not directly from AMD or NVIDIA. This is because the card makers often tweak the GPU and graphics chipsets so they can advertise this or that "enhancement" over competing card makers using the same GPU and graphics chipset.
