[Alf Hanna] “I noticed something odd, that ATI was sponsoring the booth/events. “
AMD has been a sponsor of the VASST NAB events for a long, long time. Since AMD bought ATI that makes ATI a sponsor too. This has no bearing on the fact that Vegas only supports nVidia CUDA for GPU acceleration.
[Alf Hanna] “I’ve been under the impression that Vegas users should be using nVidia cards, as it takes advantage of CUDA architecture. “
That’s correct. Nothing has changed.
[Alf Hanna] “I removed a perfectly fine ATI card from my new Dell and put my older nVidia card in it. Was that not necessary?”
The key word here is “necessary”. I have not seen any significant improvement in rendering times using Vegas with CUDA so from what I have seen, it is not “necessary”. Whether it will get better in the future is anyone’s guess. Since Vegas doesn’t accelerate anything else, ATI cards work just as good. In fact, if you have Boris Continuum Complete 7, that will take advantage of either your ATI or nVidia card because it uses OpenGL which is not tied to any one vendor. In fact, a new ATI card may have better OpenGL performance than an old nVidia card (and visa versa). So I would not say that an nVidia card is “necessary”. It is a good option if you are buying new because other video applications also have CUDA support.
