Topic: MF/PCI as system audio in W7 64-bit = High latency ASIO
In 32-bit XP and Vista, I used to assign the system audio to my MF/PCI (analog 1+2) and I had no latency issues with ASIO softsynths when running them through alternate channels (analog 7+8). I ran at 256(6 ms).
Now that I'm in Windows 7 64-bit and assigning the same channels to system and ASIO (using the latest 3.082 drivers), I was surprised that when using the same 6 ms setting Kontakt 4 had very noticeable latency (maybe 60-80 ms), while in Kontakt 3.5 it's now unbearable, seemingly close to half a second. If I assign the system to on-board audio, all is well and normal again with ASIO.
I'll have to route the motherboard audio to 2 analog ins of my MF and change the system audio when I want to listen or watch multichannel material. No big deal, but I though you should know of this change. I'm also curious to know if others have experienced this as well.
