I\'m considering reinstalling Windows and disabling ACPI as has been recommended by many, but I\'m wondering, has anyone experienced a real difference in performance? I don\'t need benchmarks or numbers, but if someone said they\'ve tried it both ways, and it works better without it, I\'d believe them.
I would stay away from ACPI. Having 1 IRQ address used for more than one periphereal is not a good thing.
Most of the PCI cards you purchase today are \"IRQ sharing compatible\" so your workstation won\'t lock up because of this.
Professional audio needs, however, cannot risk to have problems (like vicious clicks and pops at random times in the audio stream) or bad performances because of this kind of stuff. You have more than 1 IRQ so it\'s better to use them all in order to let the audio card work on a single one.
There are no risks in using a non-ACPI workstation. The worse you can is that it will be the same as an ACPI one (I don\'t think so, however).
