Having the same problem

I love you guys at CDPR, huge fan of what you have achieved, bought all your games on GoG and will defend you like a rabid fan etc etc but sometimes, you let yourselves down so badly with some basic technical issues :(

How did you manage to mess this up .... brand new content and it's not working.

I play with 16:9 on my 16:10 24" monitor because the FOV is better anyway..and the black borders do not bother me.

Altough of course this is pretty lame oversight.
