Portal 2 Failed to create D3D device stero3d

[ElementBilly]

When I play portal 2 in 2d it opens and plays fine. When I try to play in Nvidia stereoscopic 3d, the game wont open and come up with error, failed to create D3D device.

I went to the support page and tried everything in their FAQ,

I tried Drivers 266.58 and 270.61, also tried updating DirectX

I tried setting the recommended custom launch options

If I click verify integrity of game cash in steam, it says 1 file failed to validate, and it then downloads and update, but this happens every time in verify and never works.

I've also uninstalled and reinstalled the game.

Any suggestions?

Probably need to wait for an nvidia driver update. Have you posted anything in the portal2 forums? Might be worth seeing if anyone else Is having the issue

Aah simple
In the launch options you need to put in your resolution.
-w 1366 -h 768
replace the numbers with whatever your native resolution is.
