I've used 3D for about 6 years.
I had an Emagin Z800 headset which died 6 months ago after 5 years of heavy use. It used the old nvidia drivers, and frame sequential. On that the icons used to sit to the left. And my gunsight was always off (but that was realistic as I have a dominant left eye).
I now have a Vuzix Wrap 1200VR, it uses Side-By-Side (far superior way of doing 3D). It has no issues, except the gunsight which is my eyes.
Oh and skuzzy is a grumpy old fart, ignore him. If he could he'd play AH via CLI.
Here's a youtube video of me in AH (in 3D) :
