i have found very convenient using wdm drivers because you don't need low latency all the time, i only use low latency when playing soft synths . when recording audio or mixing i usually turn the buffer size all the way to 100 percent and the cpu will handle a huge amount of plug ins and tracks. when i use asio i can't change the buffer size in sonar.
by the way welcome back Phil.----- Original Message ----- From: "Phil Muir" <ddots@xxxxxxxxxxxx>

Hi all!!After a chance discussion with a friend on how good MOTU's WDM drivers are, I felt I should try using my MOTU soundcards WDM drivers, rather than the ASIO ones. 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.
