Topic: NVIDIA GeForce 760m but is it enough ?

[preslavailieva1]

Hi Guys,

I downloaded Lumion free 3.2.1.

I work on a laptop and have a ASUS n56jv with the following 2 graphics cards onboard:-

Intel(R) HD Graphics
NVIDIA GeForce GTX 760M

I have switched the graphics to run Lumion on the Nvidia card but after that i have a error message :Shader model 3 was not detected to work on this graphic card.

I installed this lumion 3.2.1. on my PC without problem.Can you help me?

Thanks guys... and btw great software

Thanks for your interest and feedback on Lumion.  

Check that you have the latest graphics drivers for the GTX 760M.  

Otherwise it should run on the laptop OK as you have correctly assigned the NVIDIA card to run Lumion.  Just to check though, please check that the setting is in the list of applications assigned to use the GTX.

yes i checked but i have the latest update.


i don`t know what to do... look this settings do you think i`m doing right

[peterm]

Those settings look OK and given you have confirmed the latest drivers then there is some issue with the GPU and in it running Shader Model 3.

Run the DirextX diagnosis:  Windows --> Run --DXDiag and post the text file results here.

Try checking the GPU with the GPU test and stress tools mentioned in this post, plus also download the PassMark Performance tool from their web site and see what it reports.

At least one of those should also be reporting Shader Model 3 issues.

this is the result  :

The GPU-Z shows CUDA is not running.  That could be the problem.  Also the ForceWare driver is 311 and current for the 760M is R331, not that an older version driver should make such a difference in running SM3.  Go to the NVIDIA web site and update, just so that we can tick it off as not a driver version issue.  

After updating the driver re-try the GPU-Z report and also the others especially the FurMark as that will use Shader Model 3.

If CUDA Computing is not ticked you may have to check with NVIDIA forums for reasons why no CUDA, or with your supplier support.  

Try also directly via Windows Control Panel removing the NVIDIA drivers and re-installing 331.  The update system is usually good, but sometimes it does tale a complete uninstall/re-install to get things working.

thank you man but when I`m trying to install R311  system answer 2 things :
1.this graphics driver could not compatible graphics hardware or
2. this NVIDIA graphics driver is not wok with this version of windows
 my version is windows 8.1 pro
should i reinstall windows?

[peterm]

I do not see any reason why you should reinstall Windows (at least at this point).

You should try using the drivers using their check system method.  Presume you mean R331 and not R311.

Once the driver is successfully installed, and if that does not resolve things, please do those other tests mentioned earlier to see if they can help identify what the problem is with your GPU.
