Let me make some summary here:
1. simple shutter output - done as promised - driver generates LRLR signal, but sync is an issue as we expected - if you think this output is senseless we can remove it
2. marked shutter output - we decided to release it also to potential cooperator who can make any device in between of iZ3D driver and shutter glasses
3. only things we can use for better synchronization is VSync and in some cases it works if fps is higher than refresh rate
4. nothing else we can do atm because of:
a. no API (for both nVidia and ATI) to access this level
b. no way to interrupt rendering thread to insert own sync signal
It does not mean we are not going to continue our search - we'lll continue. Good luck to all of us!
BlackQ, the mere thought of you 'removing' the shutter output doesnt even bare thinking about!? :s Many people have waited months and months for this functionality since you claimed you would be supporting it, so surely this is an extremely important issue (see how many hits this thread has had!). It is not done as promised as it does not generate an LRLRLR signal, it can sometimes be LRLRLRRRLRLLRR etc.
The marked shutter output is also pretty unusable as this would result in significant glasses flicker.
It is not the sync signal that is the issue, it is access to the page-flipping buffers. Sync can be generated via a simple square wave converted from the V-sync output of any card - there are extrenal modules out there which convert a vertical sync output to the standard 3-pin DDC signal required by a lot of shutter glasses.
You need to access the page-flipping capability of the graphics card to guarantee a LRLRLR output - thats your side of things. This is certainly a bug as it renders the feature useless without it.
Personally I've had an 8800 working on a CRT with 8800 Ultra running PRAY, with no problems whatsoever, so I know for a fact eDimensional have page-flipping working with their own driver. Certaintly if they can do it, iz3d can!
With respect, it would really be very,very bad if iz3d gave up on this - there is definatley a solution out there and you are in a very good position to find it. I know you have said you will carry on looking, I just find it surprising as a 3d driver software house you cannot recruit the expertise to be able to do this.
