If anyone is in doubt about the visual 3D Vision errors produced by patch 1.3, then I have captured 3 screenshots each with patch 1.2 and patch 1.3, so you can compare the difference, and study the nature of the error. I have used the default high setting. The files named "correct" are from patch 1.2. The ones named error is from 1.3. You change the file format to .jps and use NVIDIA's 3D photo viewer.
Here are the last 2 screenshots from the forest.

The introduced issues are pretty clear once you put the 3D Vision glasses on and look at them. Like I posted in other threads, I have a hard time believing that someone at CDProject actually did any testing of the "fix" without putting the 3D Vision glasses on and checking a few in game areas. I suspect they probably just had 3D VIsion enabled and saw that the frame rates were acceptable and called it a day.

This.

From my in-game experience, closing one and eye and the other reveals shadows are not rendered in the left eye of the image - combined, it makes a very distracting experience that i have to resort to playing in 2d.

It is very very very far from 3d vision ready.

It irks me that the original post after the patch was released said the considered it fixed although there is plenty of feedback, and concrete proof with the screenshots, that it isn't rendering properly. I wish one of the developers would finally acknowledge this and contact Nvidia (Andrew Fear, since he is the 3D Vision contact there) to work it out.

Can we at least get an official response from a developer about this? I hope they realize the reason there is such outcry about this is because most 3D Vision users love the game and just want it to be the showcase 3D VIsion game that it can be.

I just signed up to reply to this. I have the same problem with my 3D Vision and the shadows in The Witcher 2. I've submitted a ticket about this to CDPR, but I'd like to keep this thread near the top so we can have awareness on the issue and maybe get a developer response at some point.

I'm just posting here to add my support; if this issue is as obvious and common as it sounds, CDPR definitely needs to confirm it in some way, and get working on a fix as soon as they are able. Make sure you also send this directly to their tech support: tw2support@thewitcher.com and include links to this post and others in order to help out. They're very friendly over there. :)

I know quite a few people have reported it to the tech support page, including me. I have not heard anything back yet.

Am outside of the US - i have this issue on a 3d-vision compatible Viewsonic LCD monitor (120Hz).

you can see these errors on 50cents paper red/cyan glasses too

anyway, CDP and nVidia play the blame game

nVidia + CDP say: "So what was it like working with NVIDIA? How did the company assist you in development? Bartłomiej Wroński: Well, we [got] lots of help from NVIDIA engineers. They helped us, for example, to implement NVIDIA 3D Vision and it looks really nice in our game. They have helped us develop NVIDIA Surround and they provided lots of technical help, for example, for optimization for NVIDIA cards to make the game run very nice on new GeForce cards to make it fully scalable in SLI and also they provided us with cool equipment like 3D monitors and 3D glasses."

CDP says: "But I'm afraid that more on that can be done by other group of bloody morons, responsible for introducing 3D tech to our game."

nVidia says: well it's updated now, but on patch 1.1 it said that the game treated 3D active even when OFF, so one needed to uninstall the 3D driver or stop the servce

CDP says: "3D Vision was tested like every other change and it works without any issue. If you have any problems with it please contact our technical support."

nVidia says: "We are still investigating whether the bug is with the game or our drivers. If it is with our drivers, we will fix it. But unfortunately the new 3D issue isn't addressed with the upcoming driver and is still visible in the upcoming driver."

customers lose all the way :-|

This sounds bloody offending when taken out of context. It wasn't like that in the original text. Actually, it's wrong address. Correct one is tw2support@cdprojektred.com.

Anyway, we see the problem and are working on it.

Thank you for the correction. I received that other address from a different post, somewhere around here, and I used that to get in touch with tech support a while back; but I suppose it was changed at some point. :)

Thanks also for confirming that you're aware of the problem.

Ok. Sounds good as far as your end goes. I am not ready to jump into the 3-D stuff yet as it is too new. My HDTV is 3-D capable and I have up dtaed the Firmware on my PS3 to accomodate 3-D, but haven't purchased glasses nor software yet. I expect my first title ( well, not counting TW2 I guess ) will be Uncharted 3 for the PS3. I see from the posts that there is indeed an issue with it in the game.

Yes and no, yes it sounds more awful taken like this out of context since it was ironic, ( and since i've posted the link everyone can check the whole context ) and no it's not funny since it still said something like "stop harassing CDP since we did not implement 3D but nVidia". But hey, the 3D Vision logo is on the box, the game got sold, the nVidia fanboys took the bait, and now CDP&nVidia is looking for the culprit in slow one per month updates, either drivers or game patches. yay customer support, yay moneyz.
