I have dual 260's in SLI with 3 monitors connected (so I have surround enabled in Nvidia drivers). Before the patch, I wasn't able to play in a window but in full screen only.

However, the resolution of 1920x1200 still worked. It filled the center monitor and left the other 2 blank.

After the patch, no matter what I do, it wants to fill the entire screen horizontally, spanning across the other two monitors. Even in windowed mode, the window will span across all 3 monitors. I think the vertical resolution is working because if I select a lower res like 800x600, parts of the gui get chopped off the top (like only seeing the bottom half of the circle part of the map in the upper left).

Although it adds to the immersion, it is killing my frame rate.

I have tried different resolutions with different aspect ratios to no avail.

Any ideas?

Go to "\Documents\Witcher 2\Config" and open "user.ini".

Under [ViewPort], check what "Height=" and "Width=" say?.

Hi

Here is what it says:
[Viewport]
Height=1200
Width=1920

And just for kicks, here is my user.ini:
[Engine]

KeyboardLayout=QWERTY

[MouseInput]

Thanks for you help.

It's a pain in the arse, but make sure you have the latest nvidia driver then try backing up your saves and uninstalling then reinstalling the game.

Check it before and after patch v2.0.
