Ok, i'm opening a new topic, I had another one asking about this issue but now that I found the solution I'm opening a new one... because this is the most tricky solution I've never seen in my life (regarding to computers
i have a HMD (shutter glasses) + nvidia 8800gt, Stereo drivers "StereoE16250" and the latest nvidia drivers 196.34 for Win xp 32.
I've read many posts about the artifacts issue (that black squares moving around the screen) but no solution worked for me (used nhancer with ss 4x4, oblivion hack etc) nothing.
But now this works for me, I hope it could help some people with the same issue, I think it could work with a different setup (3d monitor, another nvidia card etc) so, I tried this:
First, installing latest drivers, then stereo 16250 drivers. Changing ContextUIpolicy and CplGroupUIPolicy to 1 (if you don't know how to do it there are posts about this) and rebooting.
And now install iz3d drivers (full instalation) and i choose dual projectors (i tried another ones and worked too)
-Now displaying windows on my HMD (800x600, 60hz):
1. Right click on desktop, Select device, 3D stereo setup && test
2. This is a little tricky (the ultimate tricky trick will come later) to activate 3D with this setup, i have to enable "always use stereo refresh rate" then launch test application (still not in 3d) exit test, now disbling "always use stereo refresh rate" launch test again... now it's in 3D!! but... full of artifacts!
3. I don't know why, how or what in the hell makes this thing my artifacts dissapear but here i go:
-Install jDownlaoder (it's just a download manager) and keep it minimized on system tray, no need to have anything downloading.
And that's it... XD the artifacts just dissapear magicly.
Now sometimes got a very little artifacts at the top of the screen but if I press ctrl + f4, or ctrl + f5, to adjust the deep just a little, dissapears definetly.
Please, if you have the same problem try this and let me know how it worked for you.
And if anybody can tell me why keeping jdownloader minimized does the trick (i tried with another programs but it only works with this one xD) let me know too, i'm very curious.
Thank you everybody and sorry for my bad english
