As per title, when is this going to happen?
Simply having the resolution as an option in your graphics menu is not supporting it, that just means the application will stretch/scale etc. to ensure there are no black borders. Correct support means that the Vertical and Horizontal field of views are designed to ensure minimal stretching.
In these scenarios you can lower a game’s field of view setting, to slightly reduce the amount of stretching though even at the lowest in game FOV, things are still extremely warped. Like any game without proper ultra wide support, you effectively get an appropriate looking centered image only. Everything to the sides of that on the horizontal plane is distorted significantly. Imagine you placed a 24" monitor right in front of a 34" 3440x1440 monitor, and had the game running on both. The image on the 24" would display correctly, and at the sides would be the stretched image of the 34" panel.
No screen shots are necessary, anyone whom has ever experienced 21:9 done correctly vs not, will know.
You create lovely looking world and want me to go off and explore the forests and country side, yet expect me to cope with the fact that one moment I am looking at a tree head on and after then turning to the side, the next time I look back at it(and it’s not all the way at the edge in my far peripheral), it suddenly went from a young tree to a really mature one due to the stretching.
It spoils immersion when you barely move and objects grow to four times their normal width. And even worse, when you’re looking at a static image and yet objects are pulled and distorted when still in your 120 degree arc.
Also, this affects horizontal plane to a lesser degree.
I am sorely disappointed that this wasn’t done at launch, let alone in a simple hot fix afterwards.
