I've been offline since getting the Butt Kicker Gamer 2, it's been a bit of a process getting it working properly. Finally last night I had a breakthrough after watching a YouTube Video by 2Old4Forsa where he details using Sim Hub and his settings.
The biggest single issue, was configuring a second Sound Source NVIDIA HD Audio through my Display Port Cable to my BenQ Monitor. I tried using the supplied splitter supplied with the Butt Kicker Gamer 2, but I was getting feedback in my headset which was awful.
Now my headset is on the Sound Card in the computer and the Shaker is on the NVIDIA HD Audio, fine tuning in progress but it's already a big improvement.
