Update:
Finally got a response from Sony Tech Support tonight but his reply was unbelievable.
In a nutshell, I was told: “My video does not contain enough effects or graphics to require the GPU to be utilized.” He said I needed to add more effects and increase the bit-rate of the final clip before I would see a difference. What?? There’s a friggin’ switch that says “USE GPU”…but they forgot to add “if it feels like being used”.
The whole purpose of buying a newer, high-end video card was to reduce the rendering time. I now have a video card that takes 3X longer than my old one. Sony doesn’t seem to have a problem with this.
It has been an awful past 3 weeks for me and this pushed me over the edge tonight. I’m tossing up my hands, going with Norm’s comment that “ATI Radeon HD 7xxx series cards don’t work with Vegas”, and returning the card tomorrow. I’ll live with my HD 6950 until I can find a card out there that will work EVERY time I render…and hopefully at 70-90 frames per second.
Is someone out there using an ATI Radeon HD 7xxx card that works every time? Please let me know. Other card recommendations? $200-$250 budget.
