Will there be a fix to the nvidia optimus problems and when? I still cannot launch the game...

Release a good update for what?
[/quote]

A release of good update so that Nvidia Optimus users can even play the game (L.A. Noire in this case).
We paid our money for Nvidia graphic card and Nvidia Optimus and we can't even run the game because of it.
Your comment is suddenly making me angry. I have the game ready and I can't even play it.

The game is locked to 30fps. That may explain some of your problems?

I think he meant Nvidia Optimus problem.

I don't think this is the proper forum to ask for help with Optimus problems. I'd call the nVidia support team, or even Rockstar's support. Or at least in the proper forum: [url="http://forums.nvidia.com/index.php?showforum=211"]http://forums.nvidia.com/index.php?showforum=211[/url]

My problems is i cannot launch the game with my grafic card nvidia optimus and i can not play with intel graphic card because it moves like a ****....So what's the problem,why not recognize my video card this game?

Don't worry, you are not alone.
It's the problem with the Nvidia Optimus and we need a new graphic driver in order to play the game.

I don't know what to tell you but convergence is not locked for me. Try holding dow the hotkeys for a longer period of time.

please post a screenshot with high convergence.

Looks like the fixed convergence won't be fixed /shifty.gif' class='bbc_emoticon' alt=':shifty:' />

So I decided to hack the nvapi.dll. That's the place where all the "3D Vision Ready" games set the hard coded convergence value.
My first try was to always fail the nvapi_QueryInterface call and copy the modified DLL to the application directory. But this resulted in no more stereovision: only the left image is then drawn. The correct solution would be to intercept the "NvAPI_Stereo_SetConvergence" call from the NVAPI SDK, but every API call is routed through the nvapi_QueryInterface DLL API with some memory/offset magic. I will now disassemble the code in nvapi.lib to see how the DLL communication is implemented to detect only the SetConvergence call..

Hello, I'm from Russia
I have problems with the launch of a LANoire 540m Nvidia Optimus
After reading forum, found that many people have such problems. When there is a solution to this problem?

Convergence fix: http://www.multiupload.com/1QX0ZM4GV3

1. run regedit.exe
2. go to L.A. Noire profile ( Computer\HKEY_LOCAL_MACHINE\SOFTWARE\Wow6432Node\NVIDIA Corporation\Global\Stereo3D\GameConfigs\LANoire )
3. delete Time (Name: Time, Type: REG_DWORD)
4. set StereoConvergence to 0x408a8cf8 (Name: StereoConvergence, Type: REG_DWORD, Data: 0x408a8cf8)
5. copy the hacked nvapi.dll to the L.A. Noire installation folder.
6. freely change convergence value using your keyboard shortcuts.

I could make some screenshots with awesome convergence, but I don't know how.

btw: my hacked nvapi.dll disables the convergence API, so any game where you put this DLL in can't set a hard coded convergence value anymore. I don't know if NVidia approves this, but I'm happy..

This sounds great, but does it mean that you can't "save" convergence settings with ctrl+f7?

Hi

For any users having trouble with L.A. Noire and Optimus, you can create your own profile for it. Here are the steps.

[list=1]
[*]Open NVIDIA Control Panel
[*]Select “Manage 3D Settings”
[*]Select “Program Settings” tab
[*]Click “Add” button
[*]Browse to and select the game’s executable you wish to create a profile for (LANoire.exe)
[*]Choose the preferred display adapter to use from the drop menu
[/list]

    this was the first thing i did. when we choose Nvidia Gpu the game crashes on launch. when we choose integrated we can start the game but it's very laggy.
