Tech Tip for July 2017
by Alissa Oder

For the past few months, we've been waiting for some good news in the continuing saga of the Windows 10 version 1703 "Creators" update disabling OpenGL stereo. Summit Evolution uses OpenGL stereo. There is finally a glimmer of hope.

NVidia beta driver 384.76 from June 29, 2017 is working for OpenGL stereo on Windows 10 version 1703 "Creators" in the following reported cases:

• Desktop with nVidia Quadro M2000
• Desktop with nVidia Quadro M4000
• Desktop with nVidia Quadro K620 (The same computer would not produce stereo with an older Quadro 4000*)
• Desktop with nVidia Quadro P4000

The customer who reported success with the Quadro K620 and beta driver 384.76 first tried an nVidia Fermi-series Quadro 4000 in the same computer with driver 384.76, and it did not work. The 4000 predates the K, M, or P-series cards. The 4000 is the oldest card we would consider trying with Windows 10, and has an older OpenGL version than the later series. The 4000 is listed by nVidia in the supported products for 384.76; I only have this one case to report that it does not work.

If your video card is even older than the Quadro 4000, for example an old Quadro FX 4600 or FX 4800, please purchase a new video card before you use Windows 10. It is futile to try to get an old FX card to display stereo with Windwos 10. The good news is that even the least expensive modern nVidia Quadro cards will far outperform those old FX cards, and you'll be happier with the results.

If you try a beta or release nVidia driver with Windows 10, please let DAT/EM know whether it worked or not, the driver number, your video card model and your Windows version number (you'll see it in Windows System Information). Your feedback helps us to provide well-informed recommendations.
