nahimic 2 lag spikes issue

hello all;

i need help with my issue, first of all my rig is :

-msi krait z270

-headsets razer tiamat 7.1

-GTX 1080 ti zotac extrem amp edition

-windows 10 pro 1709 edition

-ddr5 3000 MHz 16gb g-skills ram

when i install my sound driver (realtek hd audio driver last version) and the nahimic 2 latest version all my games got fps drops and lag spikes (PUBG, CS go, battlefield 4). during the gameplay i have to close nahimic 2 from running in background to get my games works fine but the sound is so annoying.

i tried to install the previous versions of realtek and nahimic but got the same results. So many lag and fps drops.

Please help

thank you in advance
