Dec. 18, 1999:  ELSA Revelator  native OpenGL stereo support - beta released

From the readme:

"Windows 9x driver for ELSA ERAZOR III, ELSA ERAZOR III LT and ELSA ERAZOR
III Pro; first beta driver with OpenGL support for ELSA 3D REVELATOR

This driver based on NVIDIA's reference driver 362. It supports fullscreen
OpenGL games in stereo mode with ELSA 3D REVELATOR. This driver is tested
with Quake II and Quake III in stereo mode.

This driver includes support for the special video functions of ELSA
ERAZOR III-Video and ELSA ERAZOR III Pro-Video.

Current known restrictions:
no ingame control panel visible within the OpenGL stereo mode (but it is
possible to adjust the settings unvisible)
no support for Unreal Tournament in OpenGL stereo mode (Unreal Tournament
may crash in OpenGL mode with enabled stereo while Direct3D works fine)"

Thanks to Ralf for the news update
