Firewire audio interface causing constant 20% cpu usage. Audio Interfaces

Firewire audio interface causing constant 20% cpu usage.

hey guys
i got my impact twin for about 2-3 months and so far i am happy with it
recently i saw my cpu is constantly idle at 10-25% usage with the audio interface connected.
when i shutdown the interface, everything is going back to normal, 1-5% cpu usage.

at first i thought i had some virus but nothing found with kaspersky and combofix.

the "process" causing all of it is 'system interrupts' (can be found at resource monitor).
i also tried to update all my drivers include chips. my firewire chip is integrated in my motherboard and no updated drivers found.

is anyone familiar with something like this? these 20% are important for multitasking etc..


thanks guys.

p.s tc electronic fourm is pretty dead, i've sent them an email but still no answer from their support team.

Have you done all the PC audio optimizations? Is the built in firewire chipset a TI? My Yamaha mixer is finicky about the chipset and I installed a separate PCIx card for that.

nope..no special optimizations was made. maybe i shut down some services of the integrated audio chip and windows defender other then that - i dont really remember.
and yes, it is a built in firewire chip from TI.
maybe a separate firewire card will solve it?

Does TC have any recommendations for chipset? No way to know for sure if separate card will resolve it, but I would be more tempted to do it especially if your MOBO has a non TI chipset. I would for sure do the optimizations too...you just never know..
