Another hint: While Risen 2 doesn't suffer from tunnel vision there is always room for improvement so if you have a beefy system then you can change the field of view to a higher value by editing this entry under the 'Render' section in the INI. The default is 75. As you can see I changed it to 90 which works well and does not cause a fish eye effect yet. It's nice and more natural in my opinion to be able to see more of your surroundings…
Code:
<Render
FoV="90.000000"
