Is there any full screen mode without black bars on left and right of the screen?
Yes there is in the settings but it won't work until you set your graphic card settings to fit any resolution to full-screen. Whether it's nvidia or amd or intel it's available in all of em. Just make sure your graphic drivers are latest and the setting is applied and you're good to go. Coincidently I'm playing the game these days and it's one if a kind for sure.
