The new driver uses a streaming architecture rather than an interrupt /
DPC architecture. This ensures that VAC transfers the bit-perfect audio
stream between PowerSDR and your third-party sound card based
application more efficiently and doesn't drop audio buffers like
previous versions.

Subject: [Flexradio] VAC 4.11 on WinXP
Just a quick note to say that I have installed VAC 4.11 on WinXP SP3. In
quick testing with fldigi 3.21.33, WSPR 2.21, and PowerSDR 2.3.5 I found no
problems whatsoever when VAC 4.11 was set up according to the instructions
in the PowerSDR release notes and Tim's admonition to uncheck "enable
channel mixing". There are no noticeable additional delays or any other
anomalies that I could detect.
