Proposed Fix to Stretched Resolution (In Full)
Stretched resolution is a controversial topic, since arguments for its use can be both reasonable and unreasonable. On the one hand, a significantly stretched resolution can give enough extra FOV to the point where it may serve as an advantage to the player in some scenarios. On the other hand, stretched resolution can act as an optimizer or FPS booster for the game; making DBD (a pretty poorly optimized game) more playable for those who experience optimization issues.
To be completely clear about my bias here, I am a stretched resolution user (1440x1080) mainly for the above reason, but I understand the counterarguments people have. For this reason, the changes below are, in my opinion, the best way to fix the problem while ensuring both sides feel as satisfied as possible by the outcome:
1) Optimize the game to the point where playing on native 1920x1080 at 60FPS is accessible to ALL players with reasonable hardware - INCLUDING console players who, from what I've heard, have had to suffer through some awfully optimized patches recently. This way, there is no reasonable excuse to use stretched resolution.
2) Fix the FOV issue. The only reason why some people found stretched to be an issue, was because it provided players with an FOV increase. Once this bug in the game engine is fixed, much like it was in Fortnite (another Unreal Engine game), people who oppose stretched resolution will no longer have any reasonable grounds to oppose it. It's also worth mentioning that technically, stretched res can give a disadvantage if you stretch it the other way - this is a problem that players with ultra-wide monitors experience.
3) Add an FOV slider. DBD lacks a lot of basic in-game graphics settings, and although some may disagree here, I believe an FOV slider is quite a basic one. If players want a bit of extra FOV, they can have the option (to an extent). This would include every player on every platform. In my opinion, the maximum FOV would be the equivalent of what a 4:3 or 1440x1080 resolution would give players, but I am of course biased as a user of this resolution, so I am more than open to debate on this one if people feel this is too great of an FOV to offer players.
Will be happy to hear what people think of these steps :)
