While CSN:Z has its roots in a classic era of Counter-Strike gaming, this means its game engine has limitations. The CSN:Z Team will attempt to improve compatibility and diversity of video settings when possible, so please leave feedback on the forums and in Tickets to Nexon Player Support about what you'd like to see added.
The CSN:Z Team cannot fulfill every request, but without your feedback we will not know what resolutions are needed the most.
