I tried using the tool you sent me and here are the results:
Current Latency: 666 Absolute Maximum 1971 "This machine should be able to handle real-time streaming of audio and/or video data without drop-outs."
However, I noticed a couple of drop-outs while I was measuring and they did not show any peaks in the graph, so I'm not sure if the results are trustworthy.
Also, would it be possible to contact me by the e-mail address I supplied? The reply button seems to be broken here. Thanks.
