And this is all likely to change with Vista, which may have its own driver protycol.

There's no way of predicting which drivers will work best under different circumstances. Sometimes its ASIO and sometimes WDM.Its all to do with how the drivers interact with the host software and the rest of the system. The best thing to do is try both sets of drivers and see which one comes out on top.The one thing this shows is that ASIO is not the best driver format, its just a different one.Dan----- Original Message ----- From: "Omar Binno" <omarbinno@xxxxxxxxx>To: <ddots-l@xxxxxxxxxxxxx> Sent: Friday, January 12, 2007 10:56 AM Subject: [ddots-l] Re: MOTU WDM Drivers Are Better Than There ASIO OnesHi Phil:Is this applicable with any soundcard? If I'm using a delta 44, I should also use the wdm driver rather than the asio one?Thanks.

Guess what, I have found there is 25% les CPU usage when using the WDM drivers, over the ASIO ones. I have also been able to significantly drop the buffers in the MOTU control panel too.Before, I was using the ASIO drivers and running with buffers in the control panel of 256. My CPU usage was around 30% on large projects. I then moved the buffer down to 64 and tested with the ASIO drivers. The CPU usage, jumped to around 76% and some crackling was occuring. So, just for fun, I changed from ASIO to WDM, reprofiled the card, and the CPU usage, jumped back to around 51%. Note: I have also found that every time you change the buffers in your sound cards external control panel that it is necessary to reprofile the cards WDM driver. I previously hadn't done this and because of the strange audio artifacts that I was hearing, had wrongly asumed that I had set the latency too low. In my case, I new this couldn't be right, as I had actually moved the buffers in the control panel from 64 to 128 and higher.Conclusion, use MOTU's WDM drivers, as they are much better written.
