Are there any plans to address the CPU usage issue when using Webcams from vendors like Creative and Logitech on chat programs such as Skype, Yahoo Messenger etc?
The vendors seem to be blaming MS for the issue. In short, the problem happens when you are using an USB Composite Device (Webcam with an integrated microphone) to capture video on Windows Vista using an application that uses DirectSound to capture audio, the CPU usage goes all the way upto 100% (with a Core 2 Duo 2.33GHz) which did not happen with XP on the same machine.
