In Game Mic Not Working and Now Game is glitchy

I just got a new PC and the mic works in direct steam convos but inside Killing Floor. Any idea what?



Also yesterday everything was fine gameplay wise but today the mouse is really unresponsive and slow in the game only. Same thing if I use a track pad or anything. In game it'll skip frames almost or something. Not sure how else to explain it. Everything else is fine.



I'm on Windows 8.1 :mad:



Yes I've restarted. No such luck.
