I have an update. We installed the newest version of the graphics driver 310.44 dated 2013.04.02.
Short reply: The performance was worse.
With this driver, the switch between normal and reverse stereo happens every 1 to 2 seconds and without much input from the user. This type of rapid reversal of correct/incorrect versions of the molecules is a no-go. Now, I remember that this is the reason we did not use the currently latest graphics driver back in Oct. 2012.
More on this problem. When this reversal happens image that is on the screen does not change when this flip happens. But one can’t be sure of that because it change could happen at such a rate that it is not perceptible to the naked eye. The emitter might be sending a signal to the stereo glasses that is out of phase with what is on the screen. In order for the correct stereo to be there all the time, the emitter should signal for “right eye shutter” to close when the “left image” is presented on the screen and vice versa (at least as I understand it). So with the new graphics drive, the emitter is frequently (frequency is 1-2 seconds) changing the phase of the signal to the emitter in relation to what is on the screen.
We have reinstalled version 290.10. All things being the same, with version 290.10, the phase-sync between emitter and glasses does not change once it is initiated. So if one starts out with the correct stereo, until stereo is turned off I can do my work. It is only when stereo is initiated (when going from mono to stereo) half of the times the phase starts out wrong. But it stays unchanged. All graphics software I use provide a software switch (usually buried down a few menu levels) that can “reverse the stereo”. If I use it to set the stereo back to correct image, then until the next time I switch back to mono, I don’t need to worry because the phase-sync is stable. What would be nice is to have a stable phase-sync, coupled with a “function button” that can be a toggle to switch the phase. Then, as soon as I see the reverse stereo, I can press the function button and I will have a stable phase-sync in correct stereo. In earlier devices I have used, (I have been doing this for over 22 years), there was a flip switch on the emitter to correct the phase.
I am hoping there are others who have wrestled with this problem and have found some solutions. (May be there is a setting in some file that needs to be reset). Would appreciate the help.
Nvidia might be able to compare version 310.44 with 290.10 and see what causes the frequent phase change. Then we would be able to use the latest drivers instead of hanging on to an old version that works.
Thanks for any help.
