Ok I have read throught he boards, and have not found a solution. I am running a 1.33 Ghz AMD Tbird, with Asus Motherboard, and a Nvidia 5900 ultra video card with 128 MB of video memory. and 1.3 gigs of system memory. My problem is this. I have 2 pairs of glasses and they both work fine except it sporattically flickers. Its enough to make you not want to use the goggles at all. What I have noticed is this. when the glasses are flickering the most, is when there is a lot going on in whatever game i am using. If i take the glasses off, and simply observe what is happening on the screen, i notice that my video card is only drawing half the frame. So the top few lines of my screen are flickering at the same rate as the sporatic behaviour of the glasses. yet the rest of the screen looks normal. A friend of mine suggested that I find out how to force my video card to render the frames at the same rate as the frequency of my monitor. I have tried tweeking the speed of my refresh rate. Its almost as if the glasses are getting their timeing from the video card, and the video card frame buffer is causing the problem. I have had these glasses for quite some time, and they always work the same. I have always been an Nvidia fan, so all my past video cards have been Nvidia chipsets. I have gone through 4 different nvidia cards over the years, 3 different operating systems, and 2 different mother boards and the responce to the glasses is always the same. Yet my cousin has a radion graphics card and has no problems. I read elsewhere on these boards that I can pull a certain pin on a video card cable, is this the solution? Or is the solution provided to the other guy wrong and he is experiencing the same thing as I am? | ||

Same problem here. My glasses just flicker uncontrollably, with sometimes splitseconds of 3D Images. But i discovered, the glasses flicker even if no 3D Application is working at all. Lets me think of some Interrupt Problem. In Addition the card worked twice (out of 50 Tries) absolutely correct with the Testscreen, but next time only flickering. Removing Pin 12 and 15 didn't work for me. I tried it with an old Voodoo Cable, so there wasn't any serious Damage done. Now im stuck too and would appreciate suggestions or solutions. Btw. i use a P4 3.6Ghz and a Gforce FX 5950 Ultra 256 MB | ||

Lance McP - yes, of course the glasses are getting their timing from the video card. It is the video card that is displaying either the right eye image or the left eye image on the screen, and, for it to look any good, the between these two images must only happen during the Vsync (i.e. between the end of one screen and the beginning of the next). The glasses are slaved to this and must switch at the same time as the card changes what it is displaying, or one eye will see the wrong thing. It sounds like what you are seeing is what happens when the display changes to the new frame before the graphics engine has had a chance to finish drawing it. You can check this by simplifying some of the realism settings in the game and seeing if it improves. Your system is very imbalanced in that the CPU is very slow relative to the memory and graphics card you have, so that may be playing some part in it too. Perhaps the graphics engine can keep up, but not the CPU? Wolfsreiter - doesn't sound like the same problem to me, the first one sounds like corrupted or incomplete graphics while yours sounds like unsyncronized glasses. Am I wrong in this? |
