I don't see an option above 1600x1050. Is this a hard limit? I was hoping to run at native 1920x1080. I tried in the registry but it crashed.
Has 1920x1080 support for me so not sure what's happening in your case.
Personally I suggest 1280x960 for a good balance of resolution and correct aspect ratio on 1080p screens as playing them in straight 1080p will make some things stretch which imo is not worth the extra pixels at the side of the screen. Unless your monitor automatically stretches any resolution to fit it of course. (btw this information is targeted generally towards others reading this thread, not specifically you)
