Fatal Error after starting game?

[PowersLFG]

This immediately happens anyone have any suggestions? I have verified files(twice before reinstalling)

Hmm, unfortunately after that last update I'm not able to play the game either.
I don't get any error - I click "play" in Steam, then I just get a black screen. I have waited and waited, nothing happens. I Alt+Tab and Windows tells me it's not responding.
I have 401 hours put into the game, so it has definitely worked previous to this patch!
I've verified the game cache to no avail.
Any help out there?

@Mongoose I am now having black screen issue as well. I didnt get a chance yet to try this Switch away from OpenGL to DirectX. You may also be able to fix by deleting the system_options.xml file in the %appdata%\Natural Selection 2 directory. You can find this directory easily by opening Explorer, typing "%appdata%" (no quotes), and hitting enter... Doing it soon as steam installs all the files I deleted...doing like a check off list of folders deleting and verifying files. lol

try run NS2 as Admin and/or if u ve Adobe Creative Cloud installed, disable it.

Well running this step worked for me. Switch away from OpenGL to DirectX. You may also be able to fix by deleting the system_options.xml file in the %appdata%\Natural Selection 2 directory. You can find this directory easily by opening Explorer, typing "%appdata%" (no quotes), and hitting enter.

@Powers Thank you so much kind sir, that did it! I can go back to feeling sub-standard at a game I've spent 400 hours in - YAY!

As clearly labeled in the graphics options menu, OpenGL and DX11 are both in BETA form.
The only rendering mode officially supported (as shown in the store page) is DX9
If you are experiencing crashes like this with DX9 please visit our official tech support page which is linked in the pinned topics here.
