Why do the previous two posts contain links to spam websites? Is this what spammers do now, post an apparently meaningful discussion and add links to the sites where they sell their sh17?

the problem is yours. i'm sorry to say this, and i'm among the ones who would like to see wider support of applications. but vuzix has a very clear list of supported titles and you paied for something that works with that list. anything out of the list is not required to be supported, although some titles works anyway. so whatever is out of the list is actually a bonus, not a requirement not met by vuzix.

Apparently iZ3D said they had support for vr920 and something changed in the the vr920 SDK, that broke the support?

I just feel a bit put off by the whole experience, just feels that I've bought something that's very expensive and half baked.. they should work in principal but they just don't :(

I don't know if I'm just whining about nothing, because maybe I'm naive about the technology, just I have expectations of something that this expensive (not in relation to HMD's as a whole) would have much better support..

VR920 buyers are some of the top end customers, who are therefore more likely to buy the new expensive vr1200's but I'm put off from buying anything more from Vuzix. If the support for vr920s is so bad, why would it be any better for anything else?

As I said, maybe I'm just being naive, but I would be nice if anyone else shared my perspective?

I had working combination of VR920 with iZ3D only once, but I can't figure out why, because iZ3D and VR920 didn't ever worked together on my PC.
I have few suggestions, some of them might be helpful.

1. This is because there is none "VR920 eye-switching" sync signal from iZ3D at this time, it only switch the eye-perspectives, but gives no signal to glasses.
2. Why? Try not to use iWear native drivers during this session, I mean reboot PC and launch something with iZ3D right away, without trying to play with something with iWear support. This can help.

New model of glasses support side-by-side stereoscopy, and it will be work perfectly with this mode in iZ3D,
also some games can output in side-by-side mode natively, like Avatar or Crysis2 (i think it can, not sure).

Has iZ3D ever working out on this issue?
Thy SELL you the driver, which need to support specific VR920 output mode natively, why it's not working?
Ask iZ3D I guess.

I'm also having trouble with the iZ3D driver. It seems it would work fine, except you set the 3D mode on with the OSD the picture just freezes teasing you with a lovely static 3D image.

Am I destined just to play Crysis over and over?!

Has Vuzix ever discussed working on the iZ3D issue?

I've discovered that if I manually force stereo-3D via the OSD, then I get a synced 3D image, but the picture immediately freezes (presumably because he's waiting for the next signal which for some reason never arrives).

I've now assumed that perhaps there's some change with the API in the latest drivers and that things might work with an earlier version, so I went through a couple of older driver versions available from the Vuzix support page, but with no result - well, sometimes everything just crashes instead of showing an unsynced image, but I've yet to get the iZ3D driver to work - does anyone have iZ3D with VR920 up and running and could perhaps tell me what version of the Vuzix driver software you're using?

Interestingly, Stereoscopic Player (latest version 1.6.6) worked just fine with all but the earliest version of the driver, so I'm inclined to doubt that the API has changed significantly; however, the behavior required to get stereo-3D via pageflipping differs from driver version to version - in some, the glasses switch to 3D mode automatically, in other versions, you need to enable it manually, some work in stereo-3D in windowed mode, others just in fullscreen.

I've also tried tricking the drivers by running another app that provides a syncing signal (either Stereoscopic Player or Vuzix 3D Visualizer) and then starting a Direct3D application with the iZ3D driver - in earlier driver versions, this simply doesn't help; in the newer versions, it causes a blue-screen of death with some driver IRQ fault.

I've even tried digging into the SDK provided by Vuzix to try and learn more about the hardware, but even the examples provided by Vuzix either fail to launch at all (vr920_querygpu_dx9-dx10_stereoscopy) or don't provide a correct sync signal (vr920_opengl_stereoscopy), so no wonder other developers can't build anything with this!

Now I realize that the current state of the market is that getting a good 3D experience still takes some tweaking and optimizing, but this is ridiculous - I've spent a couple of hundred dollars on a piece of hardware with drivers and third-party support that seem to be a catastrophe, now I'd even be willing to shell out more money just to get a driver so I can at least use this hardware in a sensible way but that expensive driver won't even work and no one knows why or how to fix it? Why can't Vuzix just provide a stereo-3D driver (like the nVidia driver, which I unfortunately can't use because my system is running an ATI graphics card, or the iZ3D driver?)

I don't even know where the main problem here lies - I'm more inclined to think that this is actually a problem with the iZ3D driver as the Stereoscopic Player (which is also a third-party app) works almost flawlessly with most versions of the Vuzix driver, but I'm finding it hard to believe that iZ3D would sell a driver that just doesn't work on any version of the underlying hardware driver... On the other hand, if the provided SDK examples don't even work, perhaps this is a problem more on the Vuzix side?

Sorry for venting; like I said, I'd be most grateful if someone could give me some pointers on how to get this up and running - has anyone actually seen the iZ3D in action with the VR920? If yes, what versions of the iZ3D driver and the VR920 driver are you using?

Problems with iZ3D driver

Hi guys,

I've already posted this over at the iZ3D forums but I thought perhaps someone here has experienced similar issues and may be able too help:

I'm running my VR920 with the newest Vuzix drivers (VR Manager 3.0.7) and the iZ3D 1.12 (also the latest version) but just can't get the iZ3D driver working with the VR920:

iZ3D works fine in other modes (e.g. side-by-side) and VR920 stereo also works fine (stereoscopy test and the downloadable bonus games as well as Stereoscopic Player deliver stereo 3D just fine), but when I try to run iZ3D in VR920 mode, somehow the sync signal is either messed up, does not get through or is not interpreted and I always get both images either overlaid or flickering (not actually sure I can tell the difference at 60Hz) on both eyes.

The problem is not application specific - in fact it occurs even when I try to run the static or dynamic test from within the iZ3D Control Center, nor is it specific to my PC as I've just reproduced the exact same problem on a different machine with different CPU, GPU and version of Windows (Win 7 Starter x32 vs Win 7 Home Premium x64, so the only thing I can't rule out is this being a Windows 7 problem).

Does anyone else here have similar problems or has someone perhaps even managed to find a fix for this?

Thanks in advance for your support!
