21:9 doesnt work in rdr2

[CrisGhost]

So i have a 2560x1080 monitor and on other games it works perfectly.But in rdr2 resolution only goes up to 1920x1080.

I found a fix,in the form of a system.xml file.If i copy paste it and replace it with my current file,it works but the game starts to run in 5 fps.

Here is the "fix"
