Maybe you don't have to destroy it completly: Rage wrote later on in the quoted thread, that you might be able to bend the pin a little, so it doesn't come in contact - at least not, if you make just a loos conection (half in the plug/jack/connector)
You could also try to use some thin plastic (foil) above it, to isolate it

I only use DVI to VGA adapters. Maybe that could be a information to consider.
I don't want you to destroy anything. It's just a very long guess.

No go on removing pin#7 as display won't work without it. Just a black screen. I would be interested in hearing others experiences, say with one/two projectors since i think they are analog connections. Looks like i am stuck playing the waiting game again for drivers...

PiXeL

Looked at my revelator adapter cable. one pin is missing there:

- O O O O O
-O O O O O
- O O O O X

X: completly missing.

EDIT:

Thats it!

Removed Pin X on my VGA Cable. Driver found an Analog Display, not as before my BelArtist22W. Stereo3D works without adapter nor VR920 on secondary port.

Edit:Updated first post for latest information.

Some great tweaking there

Great work, VadersApp!

I've planned to only buy a 8xxx card when NVidia is able to offer a working 3DStereo driver. But your work changed everything ...

I will go for a 8800GTX now and hope to be able to enjoy the great performance of this card with my racing sims (GTR2, RBR, RACE07, LFS...).

Is there anyone else successfully running these games using this solution found by VadersApp?

Thanks for sharing your findings with us!

Martin

I've done everything like VadersApp described in his first (edited) post.

And yes - it works absolutely stable!

My system:
Asus 8800GTX (@default clock)
Intel DualCore 6850 (@3.5GHz)
Forceware 171.23 (Beta)
Stereo 162.50
Projector BenQ PB6240 (1024*768@86Hz)
Samsung SyncMaster 940B (second display)
eDimensional shutter glasses (wired)
.
.

Games tested (so far):
GTR2
RBR
RACE07
NR2003
LFS

The image quality is a bit disappointing - even with SuperSampling 16*16 antialiasing is not working as well as with my 7800GTX.

The second downside of this solution is the need to activate vertical sync (otherwise you only see a black screen). This option is limiting fps to half the monitor refresh rate (43fps in my case). But its better to have stable 43fps than drops to 25fps in complex situations.

For being absolutely sure to get it running, I've drilled out pin 15 of a DVI/VGA adapter (-> Projector is listed as 'analog display'). But even when I'm using a standard adapter (with all pins connected) and the projector is listed as PB6240, everything still works well (even after a reboot). So I guess the trick with avoiding monitor recognition seems not to be necessary.

One hint: if you get a blue screen when you activate stereo3D by pressing CTRL-T: try to activate stereo3D permanently! I had this issue even with my 7800GTX. I guess it's the same with a 8xxx card.

All in all I think this solution isn't perfect for owners of powerfull 7xxx cards, but it's brilliant for all 8xxx users eagerly waiting for a working Stereo3D solution.

It's already here - you just have to use it !

Thanks again VadersApp for sharing your findings with us!


PS: when stereo3D is enabled on my system, it's not able to playback 'ordinary' 2D video (new behaviour with the 8800gtx). After disabling it, everything works fine again.

It´s good to hear that it works for you, too!

For AA maybe you can try rainbow Six AA compatiblity mode. As i remember the artefacts will be eliminated with turning it on, too.

I am using vista32 now. All games that i wanna play work with the VR920 proxy driver, of course only with the VR920. It also works with postprocessing. If they add the possibility to configure the convergence, it would be nearly perfect.

Amazing Job VaderApp.

/stereo3D community goes wild with applause and starts chanting: VaderApp! VaderApp!

Thank You my friend. Fantastic Work

Will this give you a drop-down list of solutions, or will it only work with LCD shutter glasses?

Regards,
Neil

Seems like a dropdown list but some work and others don't. But most importantly, shutter glasses work!

It didn't work for my Edimensional wired glasses, and I followed the instructions carefully, however I do own an 8800GT so maybe thats it.

Games I tried before giving up - Rfactor (BSOD and automatic reboot), S.T.A.L.K.E.R - very erm black! (eventual auto reboot) SOF II (error before program launch). These games used to work well with my old 7800GTX by the way.

I am surprised about the feedback now. I thought that it was commonly known that 8800 gtx work but with artefacts.

For me it works since first testing after i bought the geforce 8800 gtx nearly one and a half year ago. I found out while playing oblivion that it is possible to eliminate the artefacts ingame with using nhancers aa supersampling and with its profile for for oblivion aa compatibilty mode. So i tried this configuration with other games. Tataa it worked

Feedback wasnt as much as i thought, so i began to think that interest isnt so big because its not what you can tell a stable working solution we all awaited by nvidia. As i learned that nvidias new driver will be zalman only i was motivated to search for an alternative that is working for everybody. Thanks to my wife that she didn´t kill me that long testing weekend, because i left the dark room only to get some food and a beer

In this thread i posted my findings http://mtbs3d.com/phpBB/viewtopic.php?t=360&highlight= It was in May 2007. I searched for a working solution for the Game "Lord of the rings Online". Maybe I should wrote it in bold letters that it was for a Geforce 8800GTX

By the way: It seems that Nvidia took out the code for other than zalman solution with 174.XX drivers. Because i wasn´t able yet to get any of the beta versions to work.

@ RAGEdemon: Thanx for the nice words

@ Neil: Yep, its the old known drop down menu.

@ AlFitz: Have you tried the medical test image? Does it work or do you get blue/blackscreen? Do you forced vsync on in nhancers global options? Be sure that in nhancers Game profiles Rfactor and Stalker have forced vsync on, too.

Edit: Found a way to get the old control panel back in vista32. I also found a way to to choose shutterglasses but when activating S3d its anaglyph. It is possible by tweaking the registry. There is an entry for StereoDisplayID that holds the id of the display. Every entry i made has been overwritten after starting S3D. Would be good to know the id of the Zalman devices.

Maybe one of the proud owners will have a look in the registry and post the id?
It is found in: HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\Stereo3D

To stop the driver to overwrite the Id it is possible to change the rights for HKEY_LOCAL_MACHINE\SOFTWARE\NVIDIA Corporation\Global\Stereo3D. Tried it and was able to see medical test image without anaglyph but also without flickering.

Found information about different viewer types in NvSterCP.dll. All the old ones are there and also some new one. So there is hope

I tried it on 8800 Ultra but unfortunately there's too many artifacts. NHancer didn't help with this. Anyway, well done for getting it working on gtx!

If it works for you without blue/blackscreen it should be no problem to eliminate the artefacts.

Be sure that there is no profile active for you desired Game.
Set aupersampling AA on 4X4!
Be sure that u are using Oblivion AA compatibility mode.
The profiles cant be changed without further tricks. So it may be possible that for your desired game another AA mode is active.

To solve the problem with existing profile make a new one connect it to the exe and delete the path in the original one. After this process you will be able to change the settings, especially for the aa compatiblity mode.

An Ultra should be the same as a gtx as its only overclocked

Yes, it's a strange story about 3DStereo support for the 8xxx cards. When I've read about no working solution for these cards I decided to wait for buying one until NVidia is able to provide a working driver. I've checked here regulary because I thought this would be a remarkable - and therefore well announced event. But nothing - until I 'stumbled' over this thread. I took the risk of buying this card and was rewarded ...

The image quality isn't bad - there are no artefacts left (when applying SuperSampling and using the Oblivion AA compatibility mode). But fine horizontal or vertical lines (or small details) don't appear at all or are displayed too bold. This issue hurts the overall athmospere of the 3D world by some degree.

I think at least this solution should work for every 8800GTX or ULTRA card. If you aren't successful with these cards, maybe we could sort the reasons out together if you post your results:

e.g.

- medicinal test working: Y/N/Crashing?
- NVidia test app working: Y/N/Crashing?
- Game results (BSOD, black screen...)?

One tip again: if your machine crashes when you activate Stereo mode with CTRL-T, you should try to activate Stereo View permanently. This solved the blue screens on my (dual core) machine.

When there are at least two systems working ok, I think there are big chances for having success on other machines too!

Hope there will be more systems soon...

Martin

*yay* it works on my system too!
Followed the guide exactly (some creative modding of a DVI->VGA converter involved ). S3D with EDim wired shutter glasses on a 8800GTS and C2D winXP machine!
Its not perfect, and trying to use NVidia render mode in S3D movie players and immage viewers doesnt work at all. But the Nvidia test program works, medical test works and World of warcraft works perfectly, still have to try a lot of other games though. Will post results of my tests when i have found the time to do some more.

Yeah! Then its proven that it also works for other than 8800 GTX, too

Another Test:

Installed Version 173.68 Beta from http://www.station-drivers.com/page/nvi ... ceware.htm

These ones are working and of cource newer than 171.XX.

Is that gts 512mb or 340? I will try this on my gt tonight. Also can you confirm that the vga pin mod is absolutely necessary?

Although i didnt do the pin mod because i could find my adapter the result was the same as before. Black screens and crashes. This does not work with the 8800gt.

I've tried this driver combo and i unlike before i don't get any crashes while using it. I don't need to do that "pin"-thingy since i for some reason always could use the 162.50-stereo with my projectors anyway. (I have two vga-tv-converters between the graphiccard and the beamers and maybe that's it). However in dual-vga i don't get any sync at all. Only a lot of flicker like left and right is shifted several times a second on both the projectors. What i also can see is that i still have those black blotchy artifacts when running stereo just as before.So far i've only tried Tombraider Anniversary. Just running this game with nvidiastereo/8800GTX before caused a hard crash if i don't remember wrong. Altering the aa-compability in nhancer doesn't seems to do anything specific to this game. Need to do some more tests with more games before i keep this config or go back to my trusty 7900GT.

Ps: Tried it with dual vga and the projector rig. The behavior of the outputs of the card is like shutters are choosed as stereotype. Only a slight guess though.

Oh, by the way: Really great tweaking here Vadersapp! It does give an improvement to what i had before but i still need to get time to test some more. Return later with more results.

cheers

So you have to modify your cable pins in order to get Stereo3D with an 8000 series card? Count me out. I'm not about to start pulling pins and modding hardware just to get 3Dstereo to work. This is not an ideal solution. Untill there is a driver I can install and simply load games in 3D like before, I'm done with 3D.

If you read some of the posts it seems some have had success without the pin mod. I guess you are not very keen to try 3d, i have an 8800gt and this doesnt work so im even considering buying a gts just to try this out.

There are 2 types of gts, the 340/620 and the 512. Could you please specify which one you have?

Doesnt look like it works for the G92 chipset 8000 series for shutter glasses. In response to an earlier posting, I had vsync on in nhancer and the CP and I had a black screen in the test, forcing a manual reboot. I did do the adapter trick as well but to no avail.

Still I do have a bit of hope for nVidia solving the problem.

O.M.G. I’m about to cry. I just played Heros of Might and Magic in S-3D for about an hour. This is the first time I have seen S-3D since November 15th 2006 when I got my 8800gtx. Thank you, thank you, thank you. I can’t believe it’s been so long. This method worked perfect for me without the pin mod. The power of this GPU is so amazing, Might and Magic @ 2048x1536 4x4ssAA 16AF running well over 45FPS. I had almost pulled out of gaming, it’s so hard to have something as great as S-3D and then to have it taken away for so long. It’s like using a 32” monitor and then being told the biggest your allowed to use is 17”, it becomes not even worth it. I guess also thank you Nvidia but mostly and almost completely thank this site and all of it’s members.

ok I tried the medical test the screen turned black then blue. how do I block the pin with the dvi to vga adapter?

Hi, I`m new here. i bought me a pair of shutterglasses and a 8800gtx. i installed alll the driver but don`t get the reg edit right.

could somebody explain me how to edit the reg or post a picture of the reg and how it should look. because the video on station 6 is turned off.

ty

does that help?

yes, ty.
but for me it seems i only get a double image. and the medical test is like the old 3d book by disney.

Is it possible to get this to work with 8800gtx in sli on a samsung dlp tv. I saw at one point there was a registry entry to enable the checkerboard pattern, but that was for the drivers that didnt support the 8 series. Thanks for any help.

I wasn't able to get it to work on my Sammy. 3D requires an HDMI connection, so I tried the pin mod on a converter without any luck. Just a black screen. SLI doesn't work in any form for 3D regardless of the driver type. IZ3D mentioned making SLI capable drivers but enabling the checkerboard pattern in their drivers does not seem like a high priority right now (they are spending more time on HMD and Dual Projector compatibility). This makes sense since there are more people on this board using HMD's and Dual Projectors than HDTV's, but still a shame to have the best Stereo Display on the planet and only be able to play less than a dozen games. Maybe this will change at some point with the recent Samsung/EA discussions going on. Nvidia also showed some promise at CES with their drivers pushing an HDTV display, but alas nothing has been released yet.

Give it a shot and see if you have any luck. I don't have an electrical engineering background and there are definitely folks smarter than me on this board that might be able to help.

Does anyone know what changes in the registry when you set Oblivion HDR AA Compatibility to on in nHancer? I just recently got my 8800GTX and 3d Glasses, and they work fine, except for the artifacts. However, I don't want to install nHancer since I don't install .net apps. If someone could help me get this work with the standard nVidia control panels (either the new or old one) or regedit, I would be very thankful!

i just used the devil tool to unlock the old panel. is easy

OK, so I figured it out that all the profile information is stored in the c:\windows\system\nvapps.xml file. So could someone who has 3d working on their 8800 post their copy of their file? I think I've identified the AA compatibility mode for Oblivion, since there's an aa_feature_bits line in the Oblivion preset profile (and these lines are AA compatibility modes from what I can gather), but I've tried adding that line to other profiles to no success. Is nHancer doing something else that I don't know about besides editing the nvapps.xml file?

OpenGL games all crash for me when I try to open them with 3d mode on. Has anyone else made any OpenGL games work with an 8800?

hi ezzelin! i dont have the answer to your question, but it is much easier that somebody replies to you if you open a new topic..

have a nice day
igor

Borrowed a 9800 GTX and it doesn't work. Tried all drivers that support the 9800. Without pin, same story, it always crashes on the enable stereo test with a blue screen.

Also tried anaglyph with the iz3d driver and it works, but at 1024/768 in rfactor (when there's a lot going on and all details on) I only get 9-10fps compared to 6-7 with a 7900 gtx. 1920/1200 is K.O.

I have a 7800 GTX 256mb and I´m thinking to buy other better, now that seem to work using this procedure. I have crt+shutterglasses and planar too (now I use planar mode, but without opengl because planar type doesn´t work with 1xx.xx combo drivers using TFT monitors. I must test this that you say to see if I can use my actual 7800 gtx with 1xx.xxx stereo drivers.

But thinking about to improve my videocard, what I buy ?:

- 8800 GTX
- 8800 GTS
- 8800 GT
- 8800 Ultra

Are all the same in terms of compatibility with this "tweak"?. Would be a good idea to buy a 9xxx videocard, or it´s totally incompatible?.

it seems only g80 based cards work, 8800 gtx, 8800 gts (the old one with 320 and 640 mb ram), 8800 ultra (not worth, it's $500 if you can find it, gtx overclocked is the same)

Is there a reason removing the detect pin from DVI wouldn't work? I would need to use non-scaled modes and that requires DVI.

Now I need to find an 8800GTS 320mb, or rather, figure out how to pay for one . ($150 wouldn't be trouble, and they are available at that price, but I just spent $200 on a new mobo/cpu hs/fan)

XFX 8800 GT eXtreme 512-GDDR3 (G92, not G80) doesn´t work for this?. There is a man that offer me this videocard, but is not G80 based card.
