500 points to that guy who helps me resolve the following problem: with Creative GF3Ti200, WinXP and Detonator 23.11 with Stereo drivers, the picture flashes on my ELSA Revelator 3D glasses. It seems the picture is not stable and the sync signal used for synchronizing the glasses is somehow corrupted. It began to happen suddenly and neither re-installing nor totally uninstalling, wiping the registry and the installing of the drivers does not help. I really don't want to reinstall the WinXP itself so I am looking for another solution. Before, it sometimes hapened in several game titles, but now it happens even in 3D test application which is part of detonator drivers. Are there any users of Revelator 3D out there to help me?
