| Hi everyone,
I'm sure I'll be back after this question because the right eye of my unit had a blank white screen for 15mins this afternoon (after one day). Bad times.
This question is related to stereoscopic 3d in second life, but most likely applies to other games also. When I'm using second life in stereo3d, then switch to mouselook, the screen shakes. If I keep the camera just behind the head, its not as bad. It ruins the experience some what because the mouselook is more "immersive".
I have tried changing all the settings in my graphics card and in second life. The only time I can get stereo 3d to an almost usable level, is when I reduce the graphics to the lowest quality, then turn off "opengl VBO (vertex buffer objects)" in the hardware options of second life.
The only problem when I remove opengl's VBO is that any movements feel like my eyes are being cut! (Its a weird feeling when its not on)
Has anyone experienced the shaking problem in stereo3d before? Is it simply that my graphics card (MSI NX8500GT), RAM (1gb) and CPU (intel pentium 4 630) is just not up to a stereo experience?
Thank you for your time  |

| I have been doing a bit of playing around with my settings, and I found that reverting back to vsync=off fixed the shake, but returned me to the screen tearing on the top and bottom of the screen (which led me to put vsync=on in the 1st place.)
It's at an acceptable level for me now, but there is still a problem when moving around a scene.
If I *very slowly* move around the scene everything is ok. If I move at any normal speed around the scene, the is a kind of lag to the image which hurts my eyes.
This lag doesn't appear on my monitor, but it does on the vr920. Is this something to do with the refresh rate or maybe a problem with my graphics card not updating the frames fast enough?
Are there any people out there with super fast graphics cards, who use the vr920, yet dont experience these tears when moving around a scene/world?
Thanks |

| I'm experiencing your problem too, I've got an intel core2 duo t7300 and a nvidia 8600m gs 512 mb so no big hardware...
Unchecking the vbo helped a lot, but still some problem in mouselook, the bottom is shaky anyway...
hope vuzix will give some hint... |

| The reason for this is that the SL developers didn't quite design this draft of SL very well.
If it's not getting a consistant high framerate, then it assigns the left eye to both eyes, then the right eye to both eyes.
SL's an incredibly resourse sapping game, despite it's lower level graphics. It's the whole concept, since you can't use meshes, overcomplicated and laggy meshes are neccesary. |

| | I was suspecting something like that. My cpu usage goes up to 80% when i use it. Anyway, the newer things like emerald or meerkat seems to be quite faster and with better graphics. So, once again, why Vuzix, don't you release the sl modifications as opensource so someone can get them and integrate them in this next gen viewers? Sl client is already opensource and the Vuzix SDK is available, so i don't see any secret to be kept here... |
