I just wanted to share a recent experience with an ASIO performance issue.
I was getting a very spikey reading on my ASIO performance monitor within Cubase5 and clicks, pops and slow down on playback of complex projects. I tried a number of things including different ASIO drivers but in the end I found that the problem dissappeared when I plugged my laptop into it’s mains charger.
I’m guessing that even when everything is set to ‘highest performance’, when running on battery this is sometimes not enough! For reference my setup is;
Cubase5 (and Halion Symphonic Orchestra 16bit edition)
Dell Alienware M15x Laptop with Intel Core i7 740QM 1.73 ghz 6mb cache
8gb RAM, onboard Nvidia HD sound chipset.
Hope that helps!
