I am adding a a new computer to my system and will migrate the Nividia 8500GT to this computer from my current editing computer. I will probably make a small step up to a Nividia 8600GT for the dual DVi outputs.
My real question is with preview. I use vegas pro and when previewing full screen to aseconday monitor the play back is studdered. I assume this is a video card processing issue. Please help me to understand this issue so I might resolve it for the upgrade.
I have some similar issues with Nvidia 8400 GS. In this case though it's the advertised h.264 support on the nvidia that is not helping anything. After trying to play h.264 files on my machine and seeing little improvement in the performance and no reduction in cpu use, it seems the h.264 decoding is still being done by the CPU rather than the video card.
This is using files from an Aiptek sd card HD (1280x720p) camera. The dual-core 3.0Ghz cpu machine with the 8400GS only plays 20fps where the actual rate is 30fps. Looking back on the boxtop wording, it says that h.264 blue-ray and hd-dvd is natively supported on the video card. Maybe the Aiptek does not make compatible files for the nVidia hardware????
