My system–a three-year-old dual-Xeon workstation with 8GB of RAM and an Nvidia Quadro FX4800 graphics card–rendered the project to Sony’s. I set up a 15-minute timeline with several high-definition video clips, and then I added a ridiculous number of effects and transitions, but I made sure that they were all GPU-accelerated ones (Vegas groups them in folders, but they are otherwise unlabeled as such). I had to dig around on Nvidia’s site to find an even newer driver and though it wasn’t listed as the recommended driver, it enabled the option for GPU acceleration once I installed it. This requirement led to an odd glitch in my testing: I discovered that my graphics driver, even though it was only a few weeks old, caused Vegas not to offer GPU acceleration. Your system must use a graphics driver that supports it, too. ![]() Your graphics card must support OpenCL (Open Computer Language), but such cards are now pretty common, and you can buy them from either AMD or Nvidia ( Adobe Premiere Pro CS5.5 supports GPU acceleration only with Nvidia cards). ![]()
