Hi,
(Sorry for this a little bit OT post, folks).
The PCIe FAQ document @
http://www.microsoft.com/whdc/system/bus/pci/PCIe_FAQ.mspx
tells that Quality of service (VC/TC and isochronous support)is not supported
on any Windows version. Why has that been decided? How it can be garanteed that
a sound card at PCI bus behind the PCIe-PCI bridge gets the high enough
priority what is needs for low-latency performance? Is the system BIOS only
responsible for that? On almost all current PCIe motherboards the are problems
with audio performance so that they are not recommended for serious audio work.
Without QoS support it's very difficult and expensive to pick up the right
combination of components to make a DAW PC - you never know if the graphics
adapter, motherboard (&CPU, dual core CPU's are another source for problems)
and audio card combination is right for you.
-Mikko
