I am playing this game in 2023. and it is October. And I have the exact same issue. I checked with a friend of mine and he confirmed the same issue. However he has 1920*1080 as his default windows resolution, so he does not get crashes. I have larger monitor and higher defalt resolution. Is this pure incompetence on dev's part? 2+ years and no permanent fix for something as standard as resolution setting?
I read through and it is exactly same issue: C:\Users\Robin\OneDrive\Dokumenter\Mount and Blade II Bannerlord\Configs\engine_config files save and show changes, but game does not respect them and falls back to "Desktop resolution". My issue leads to worse than stutter, cause it makes battles crash. I found a workaround and a possible culprit (in my case). Cause whenever it crashes I get asked if I want to start in safe mode or not. I reply "No" and continue. But I think this sets monitor settings back to default no matter what. Leading to a new crash no matter what I set. So with this in mind my workaround is to set the settings. Restart game to avoid the "Start in safe" mode question. Then I can see that it respects and have the settings as defined in "engine_config" file. But only in the main menu. As soon as I load up a game and check its back to "Desktop resolution"..... sigh..
It is mindblowing to see such an old problem resurface (or was never fixed?) over 2 years later.
Why is this set to "resolved" with no ending comment on the issue? Do not seem like it is solved ... at least not properly!
