My specs are Q6600, 6GB DDR2 800mhz, MSI 5850, two 750GB WD Caviar Blacks in RAID 0.
I'm recording using the compressed codec and at 720p 60fps. The captures are perfect looking. Sometimes it'll say I got some dropped frames but the video still looks fine anyway. But in the videos that don't even get dropped frames, random parts will have the audio delayed by about a second and other parts it'll be in sync. Its not like the whole audio track is delayed where I could just move it in Vegas Pro, its random parts and is extremely hard to pick out the origin of each delay.
I really don't know why I am getting these problems. My specs are way more than enough for this card. Its given me all kinds of issues thus far.
