I still routinely use Nvidia 3D vision to build protein structures into electron density maps. Nvidia hasn't updated the driver in generations, and no new compatible displays or parts have been made in eons, but it's an invaluable tool. My concern is that Wayland is going to kill it entirely. There is definitely a market for this.
I'm using a Dell S2716DG which is a 27" 1440p TN panel at 120 Hz. As far as I'm aware, there were only ever a few 1440p models that got 3D Vision (officially). I've tried running 3D Vision on an OLED ultrawide I have, and it works, but only on the bottom of the screen. I assume something to do with the refresh rate (144 Hz) or pixel response time (which I think isn't great with OLED).
I'm driving it with an A4500, on Linux (openSUSE mainly), 3-pin to the USB emitter, with glasses. The A4500 is somewhat gimped because only the 470.xx driver works. With the newer drivers X11 detects the display and emitter but displays both frames simultaneously. I think it might have something to do with the stereo declaration in the xorg.conf file being different with the newer drivers, but I'm still chasing down that lead.
