Hello! I have Chimera working wonderfully with sequential stereo under Linux with our Quadro card (a K4200), but am getting terribly frustrated with trying to have it work at all under Win 8.1. The latest non-beta driver is installed. It took me a while to find where the nVidia control panel is located after finding that Chimera didn't recognize any stereo-capable hardware (including some references to togl and pixels). Blah. I started up the "wizard" of 3D, which gave me a nice slide show, but Chimera didn't see anything. Interestingly, rebooting directly into Linux gave the same problem, which had me fuming and frothing all over the place. A shutdown followed by fresh start into Linux reset the card. So the Windows driver touches something inside the card which has to be reset hard. There are multiple things installed when this driver is put on the system. Is it possible that there are things I don't want, which are slyly strengthening my thoughts about Windoze? Some searching of the archives was inconclusive for this system. I have played with the settings in the control panel but have found no combination that gets sequential stereo working. Does anyone know what settings should be changed from the defaults to get this working? Many thanks for any help!
