Dear all,
thank you for the info.
I have also noticed, that NVIDIA is not supporting 3D Vision activelly.
You cannot even buy the glasses in our local distribution.
I have just learn, that Plastation VR headset should be working without
much trouble both Windows and Linux and has reasonable price.
I will let you know, once I know the results.
Best regards,
Jan
