Massive FPS Lag with CS:GO when Teamspeak3 is open.

Hello all

Ive started to get a issue with both CS:GO & Teamspeak.

The problem is when i open Teamspeak when im playing CS:GO i get massive FPS drops. Ive got my fps capped at 140 & when i open teamspeak3 it drops to 5/10 fps. The game is unplayable. I dont need to be connected to any servers on ts3 just have it open.

Im currently running on windows10 pro 64bit.
Ive got the latest Nvidia driver installed.
Ive got the latest version on ts3
CPU : i7-4790
MEMORY : 16.00 GB
GPU: GTX970 -sli

I tested it last night on windows8 and there were no issues.Ive also posted a help topic on the steam forums if i get a update i will post.

Any ideas on a fix?
