I'm trying to get the game (Enhanced Edition) to run on my Nvidia Surround setup but it just keeps giving me 1920x1080 on the center screen and blackens out the other 2 screens. In the options menu I can select 5760x1080 but it doesn't change anything. Has anyone actually got Nvidia Surround to work with The Witcher 2 Enhanced Edition? Can't see what I'm doing wrong, works on all my other games.

Game version: Latest from GOG.com (3.0.20054.8512 it says in the witcher2.exe).
Nvidia Drivers: 301.24 (BETA) also tried the stable version.
GPU: GTX 680.
OS: Win7 Ultimate x64.

Best regards.

Doesn't work for me, either - nVidia Surround worked correctly pre-Enhanced Edition, but it's now pillarboxed.

Same issue here. I was really looking forward to trying this in Surround now that I've upgraded my system.

Anyone have a suggestion regarding how to get the game to actually display in the 5760x1080 resolution it lists in the configuration?

Changing the aspect ratio to 12 made a slight adjustment. After playing with it a while I finally found a setting that seems to work correctly for full Surround at 5760x1080 in both 2D and 3D!

In the C:\Users\home\Documents\Witcher 2\Config\User.ini file under Rendering:
Try setting AspectRatio=5

It's also recommended to make some further tweaks for 3D. Taken from the nvidia forums:
Go to where it says viewport and underneath your resolution paste
ConvergenceClose=0
ConvergenceCutscene=1.7
ConvergenceInside=2.7
ConvergenceOutside=2.7

Thank you Natai!

AspectRatio=5 worked like a charm!
