opengl quadbuffer just shifts image -- no double image

I’m trying to use opengl stereo 3D with nvidia 3d Vision in CloudCompare and AgiSoft PhotoScan. I’m using a Quadro K600 on windows 10 insider preview 15058.0 with quadro driver 378.66 (although it’s weird, there seems to be a GTX driver that is also 378.66 – is this the same driver?). The test apps work fine, but when I enable 3D in CloudCompare or PhotoScan, there is no “double image”. Instead, the scene just shifts to one side a little bit. Help!?

I just tried NvStereoUtilityOGL.exe and it only shows the left eye (switches to right eye if I press S).
