Try updating your drivers,
Reinstalling direct X
And maybe Verifying the integrety of the game cache.

My laptop shows "CRenderDeviceDx9::InvokeCreateDevice():
Failed to create D3D9 device, D3D9 is not working on this system." when i open my Dota 2. This is information about my computer :-

My laptop model is Lenovo Ideapad Flex 14.
Windows 8.1 Single Language
Processor: Intel(R) Core(TM) i5-4200U CPU @ 1.60GHz 2.30 GHz
System type: 64-bit Operating System, x64-based processor
Resolution: 1366 x 768
NVIDIA GeForce GT 720M

I tried fixing the problem first by using properties>launch options and entering commands i found online such as -noborder -windowed -w 1920 -h1080 -dxlevel81. I relaunched multiple times and none of it worked.

Then i remembered i hadnt yet tried verifying integrity of game so I did that and then tried all of the console commands from before still with no success. I tried updating my NVIDIA drivers and then tried the console again. Still didn't work.

I hope you guys can help to fix this out. Thank you.

Hi, Had you tried with -w 1366 -h 768? since that's the resolution you're using.. also had you updated directx? try those two.
