Error: PhysX: Invalid Cuda context! Steam initialized

Hybridx1

Hello,

I had purchased NS2 a while back and played for a long time. I reformatted hard drive a month ago and never reinstalled it. In attempts to show the game off to some friends I tried last night 8/6/2014 to re-downloaded and play NS2. Instead of being able to play the game I was given an error that says "The application has encountered a fatal error"

Log.txt reads the following;

Build 267
Windows 8 64-bit (build 9200)
Error: PhysX: Invalid Cuda context!
Steam initialized

Does anyone know how to fix this issue?

Thanks in advance for any advice.

The physx error shouldnt be the reason of your application crash. Last I heared, the physx error could be ignored.

You may start with being sure ns2 is fully removed before you reinstall, including settings.

I reformatted my whole hard drive. I would think that would clear NS. Either way, I followed your guide - reinstalled NS and have the same issue. How can I ignore the Physx Error?

the physx error isnt related, just... dont look at it.

if you reformatted, please make sure to install directx, then try and launch the game again.

Directx 11 is installed.

Some workaround:

1. Try right click on ns2.exe and run from Administrator. If it not helps, then:

2. Go to: %appdata%/Natural Selection 2/system_options.xml

And change this:
<device>D3D9</device>
to this:
<device>D3D11</device>

Start the game, try compile shaders by connecting to any server, after that bring back D3D9 via ingame options.

Yea that error just means physx isnt being used. This happens for AMD cards or NVidia users who havent installed physx (which is done with every nvidia driver) or its corrupted etc.
You should be running in DX9 mode as metroid suggests.

If this doesnt fix your issue please attach your techsupport.zip file that is made from your techsupport.exe located in your ns2 folder, immediately after crashing.
Something tells me you have a bigger issue than physx or dx11 tho..

Running as Admin does not help. I tried your second option but could not find the system_options.xml -The only thing inside the NS folder was the log.txt.

The issue may be larger, but it's only with this one game. Will look for the techsupport.zip.

Techsupport.exe is located in your ns2 install folder.

attached.

Do you have a pagefile set to a sufficient size?

Hybridx1

Can your further explain what that means?
