Make sure Vsync for Direct3D is enabled and make sure Poll With Interrupts is
enabled in the Game Controller control panel applet.

Hi,
  I just bought ELSA's 3D REVELATOR glasses (infrared version) and I'm
having problems to make them work. In store they performed ok, but at
home I installed drivers without trouble, tweaked monitor refresh and
tested some soft. The screen seems ok ('double' image), and the glasses
appears to be ok (i did made them flicker with just a tv-remote).
  It seems that there is no infrared signal flow, I suppose it's
related to a V-sync signal or something, I tried to adjust everything I
think about with no success (i used a 'PowerStrip' app to change h&v
polarity, etc).
  I've seen what this babes can show, and I AM DESESPERATE to make them
work!
My system:
PII 300, 64 RAM,
Win98 + DirectX 7
video: Teppro Impact TNT2 (Nvidia's Riva TNT2),
monitor: ViewSonic E771 (17")
Thanks in advance.

I know this is a stupid question, but did you plug the IR passthru cable
into your card, and put the IR transmitters in a place where they can
irradiate your forehead?


Here is what Elsa Tech Support told me by now:
'Dear User
The number one cause is to search in the DDC (display data channel)
handling.
We use the DDC channels in the VGA cable to steer the stereo glasses. We
switch the DDC data line (pin12) to close and open the right/left eye
of the stereo glasses. The 3D Revelator works correctly while the
monitor is using DDC.
The synchronization of your glasses is off, therefore interrupt the
connection of pin 12 and 15 behind the the VGA cable adapter of the
ELSA 3D Revelator.
Regards Elsa Tech Support'
I do begin learning about DDC. I'll post again when my brain dry out.
To Dave: How can I change that Direct3D setting? Poll is ok.
To Glenn: No problem with that! ;)
Thanks.

I'm using Revelators w/ an Elsa card, so this is how it works there (haven't
tried the generic drivers that come with the Revelator.)
Go to the Advanced section of Display Properties, select the "3D settings" tab,
and make sure "without waiting for Vsync" is not checked.

appears to be ok (i did made them flicker with just a tv-remote).
I had a great deal of problems getting them to work. Turns out it was
my monitor wanting to control the ddc lines and not allow elsa to use
them. If yours is doing the same then the glass will most likely
flicker all the time, even when not using them with a 3d app like mine
did. 
Since yours are not flickering except when you use a tv-remote on them
you might want to look elsewhere. 
I ended up having to buy a monitor adaptor plug from an electronics
supply  and cutting the ddc lines inside that adaptor then putting it
between the elsa connector and monitor.
good luck

Ok, I understand. But the generic driver from Elsa take out all the
setting from the Nvidia Detonator one, and keep only a tab for Elsa
glasses settings ;( It removes DirectX, OpenGl, Tv-out settings!!
Thanks anyway.

Yes, I don't have any flicker.
I did put a passthrough cable from an old 3dfx between the elsa
connector and the monitor, with pins 12 and 15 bended but without
success. Is that what you did, just take those pins out?
I did think in your solution but maybe you could give me more info.
I tried also to change monitor setting in Windows (using standard
monitor, removing Plug&Play, removing DDC...)
Thank you.
