Add me to the list of users with high cpu usage on one core due to "system interrupts"
It happened after I had to reinstall windows because windows update was broken for the last two CU's so ofc after a fresh install this issue appeared and after some googling I assumed one of my driver's was broken.
So I reinstalled again paying attention to the cpu usage after each driver and piece of software I installed and bam as soon as I installed the latest icue the issue came back.. great knowing I did an extra reinstall and wasted 3/4 hours extra than I needed to so thanks for that Corsair.
