Subject: [ddots-l] MOTU WDM Drivers Are Better Than There ASIO Ones
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.
