According to me, I found some information from some sources that this game does not support eyefinity surround monitor. It also came to my notice that it was not even running in the resolutions when manually editing the Config File. So you will be having this one
C:\Users\<user>\AppData\Local\Risen2\Config\ConfigUser.xml
and you need to change your resolution
Code:
<Window
Top="0"
Right="5040"
RefreshRate="60"
Left="0"
Bottom="1050"
AdapterNumber="0"
>
\Steam\SteamApps\common\risen 2\data\ini\ConfigDefault.xml
you will be then having an <GUI> section with common aspect ratios. And you need to add 48x10 aspect ratio:
Code:
<Aspect48x10
VirtalWidth="1728"
VirtalHeight="1080"
EnableDrawScale="True"
>
